Definitive's Extraordinary Bipolar SuperTowers with Built-In State-of-the-Art SuperCubeTechnology Powered Subwoofers
If you love great sound you must experience the magic of Definitive's BP7000SC Bipolar SuperTowers. Their patented combination of bipolar technology (for rich life-like, room-filling, three-dimensional sound) and built-in SuperCube technology subs (for lightning-fast, earthshaking bass) delivers absolutely unsurpassed sonic performance. Combine them with perfectly matched Definitive centers and surrounds for an extraordinary home theater system which is, to quote HDTV Insider, "a mind-boggling sonic achievement."
Each BP7000SC combines a built-in 14" SuperCube® subwoofer driven by an 1800-Watt class D amplifier and two pressure-coupled 14" Low Bass
radiators for an astounding 461.6 square inches of bass radiating area per speaker! That's 10% more area than a single 24-inch woofer but with better control, speed and detail than a single big woofer could ever deliver. The low-frequency performance sets new standards for speakers priced under $50,000 a pair, with bass extension to 11 Hz, extremely low distortion and tight transient response. A pair of BP7000SCs goes lower than and has the bass impact and output level capability of seven SuperCube® I subwoofers combined. The dual built-in powered subwoofers achieve dramatically better blending, integration and timbre accuracy than could ever be achieved with separate subs.
Each BP7000SC features bipolar D'Appolito front and rear mounted driver arrays each consisting of two high-definition cast-basket 6-1/2" bass/midrange drivers surrounding a 1" annealed Pure Aluminum dome tweeter. Linkwitz-Riley crossover networks do a superlative job of seamlessly blending the drivers for totally homogeneous sonic output as if radiating from a full-range pulsating sphere.
This extraordinary speaker sets a new reference standard for ultra-dynamic high-accuracy loudspeakers and achieves equally superb performance with both music and movies. They will reproduce a silky smooth, incredibly detailed wall-to-wall, floor-to-ceiling sonic image with superb dimensionality at lifelike volume levels with a sense of ease which is truly remarkable. As with all Definitive's bipolar speakers, they have an almost magical ability to recreate a stunningly realistic holographic sound field. The elegant styling features beautiful sculptural refinements to Definitive's signature look with a classic piano-gloss black finish.
Bipolar Technology Brings Performances to Life in Your Home
Many experts and in-the-know listeners agree that bipolar speakers are absolutely superior for both music and home theater. What is responsible for the unequaled sonic performance of our bipolar
speakers? Each speaker incorporates two complete sets of drivers, one facing forward and the other facing to the rear. Thus, our bipolar speakers radiate the full sonic spectrum both forward and rearward in an omni-directional pattern, exactly as sound is produced in real life.
The sonic benefits you hear are dramatic! This unique technology provides you with a lifelike balance of early-arrival sound information, which provides focus, clarity and location data, and properly delayed late-arrival information, which conveys the lush three-dimensional soundstage of a live music or cinematic performance. This combination creates a huge soundfield which is rich, warm, ultra clear and vibrantly alive. Bipolar technology assures a superb panorama of lifelike sound for every listener in your room wherever they sit or stand. Most importantly, however, Definitive's bipolar speakers make the walls of your room seem to disappear and, in effect, expand the size of your room into the sound space of the recoded event your system is reproducing. They will literally bring your music and movies to life in your home. One listen and you can never go back to conventional speakers again!
Movies and music are reproduced with unequaled purity, transparency and lifelike realism. These elegant, slender towers seem to disappear in a huge natural soundstage which extends in a three-dimensional arc beyond the speakers with front to back depth which can be almost magical in its ability to recreate the illusion of live music or cinematic action actually being performed in your room. This combination of high resolution, magnificent soundstaging, awesome bass and explosive impact literally envelops you in what is absolutely the ultimate listening experience.
Why High-Definition Built-In Powered Subwoofers Are Better Than Separate Subs
Besides eliminating the need for a floor space-hogging separate subwoofer, integrated subs offer dramatic performance benefits. First is the obvious benefit that you'll have two subwoofers in the room instead of just one for simply more bass output. Most importantly the subwoofers are perfectly integrated with the mid/high section. Audiophiles often spend dozens of hours moving and adjusting their subwoofers' crossover and phasing controls in pursuit of perfect subwoofer to main speaker "blending." With the BP7000SC you won't have to go through that kind of hassle to get audio perfection. Definitive's engineers have perfectly adjusted the crossover and phase between the subwoofer and main speaker sections to achieve seamless blending and life-like sound. All you have to do is set the bass volume to match your room and taste then sit back and enjoy audio perfection.
Home Theater Magazine agrees, "... it's a concept we heartily endorse ... integrated subwoofers are actually better than a separate subwoofer. First of all, you always have two of them and using two subwoofers helps minimize the detrimental effects of room modes, so you typically get smoother response than you would get with a single separate sub... Second, there is really no downside to using the speaker cabinet for the subwoofer ... Third, and most important, the interface between the subwoofer and the rest of the speaker is designed by the manufacturer and optimized for the drivers and cabinet used in the speaker [for] a nearly perfect blend between the subwoofer and the rest of the speaker." The result is a combination of delicate musicality plus thunderous power which allows you to experience truly awe-inspiring deep rich bass response effortlessly extending down into the range of purely physical subsonic energy that shakes the body and stirs the soul.
Narrow Monocoque, Non-Resonant, Low-Diffraction Cabinets Maintain Sonic Purity
The cabinet of a loudspeaker plays a large part in its sonic performance. We are often asked if our attractive, slim cabinets are designed that way for styling or for performance reasons-and the answer is, "Yes, both." Narrow cabinets dramatically improve three-dimensional imaging. In addition, diffraction, or the secondary radiation of sound caused by cabinet edges, grille frames and other protrusions, can color the sound of a loudspeaker and impart a "boxy" coloration. The design of our bipolar SuperTowers reduces diffraction to an absolute minimum by flush mounting drivers on extremely narrow baffles with radial edges covered by a frameless grille "sock."
The resonant vibration of a loudspeaker's cabinet walls and baffles can also impart coloration. The tri-chambered monocoque cabinets of all Definitive SuperTowers are constructed of extremely thick, dense medite with foam damping pads and extensive internal bracing. This virtually eliminates cabinet vibrations and resonance which would otherwise interfere with the pure sound produced by Definitive's high-definition drivers.
Definitive's High-Definition Die-Cast Basket Drivers are an Engineering Marvel
All the bipolar SuperTowers utilize multiple arrays of Definitive-developed magnetically shielded high-definition cast-basket bass/midrange drivers for significant performance advantages in the areas of upper bass reproduction, lifelike midrange clarity and dynamic range. These sophisticated drivers are engineering marvels which incorporate deeply drawn mineral-filled polymer cones, combined with butyl rubber dust caps and surrounds, high temperature vented voice coils and massive magnet structures. This combination of features assures high definition, superb transient response, high efficiency, high power handling and extended linear response. In addition, the aerodynamically designed, non-resonant, cast-magnesium baskets minimize reflections of the sound radiating from the back of the cones and preserve structural and magnetic integrity.
Definitive's Moving-Coil Pure Aluminum Dome Tweeters
The accuracy of high frequency reproduction really sets apart a great loudspeaker. The magnetic fluid-cooled moving-coil pure aluminum dome tweeters Definitive developed for the bipolar SuperTowers are of a unique design that synergistically brings together the performance advantages of metal domes (greater clarity) and soft domes (smoother sound and better dampening) in one state-of-the-art tweeter design.
The pure aluminum dome is specially annealed (to "relax" the crystal structure) and acoustically loaded by a precisely configured acoustic phase plug/lens (to assure perfectly controlled, absolutely linear movement). The tweeter's voice coil sits in ferro-magnetic colloidal fluid which serves to cool the voice coil for exceptional power handling and also damps the system for smoother response and sonic accuracy. In addition, the unique silk surround provides better dampening and wave termination. The audible benefits of all this highly advanced engineering include velvety smooth extended high frequency response (beyond 30 kHz), greatly reduced distortion, improved transient response, notably higher definition and crystal clear life-like clarity.
Symmetrically Concentric D'Appolito Focused Field Driver Arrays for Improved Wave Propagation
The BP7000SC incorporates four upper bass/midrange drivers which are arrayed on the front and rear baffles in two concentric pairs, each pair surrounding a tweeter. The tweeter acts as though it were mounted, in effect, right in the center of one large driver. This symmetrically concentric (or D'Appolito) point source mounting results in more coherent wave propagation with further improvements in the areas of driver blending, depth retrieval, lateral imaging and dispersion. In addition, the early arrival soundfield is focused away from the floor and ceiling and directly at the listener for even greater clarity.
Phase-Coherent Crossovers for Perfect Driver Blending
The crossover network of a loudspeaker is the real heart of the system. It is like the conductor of an orchestra, telling each driver exactly when to come in and precisely how loudly to play. Here Definitive's talented engineers really work their magic, perfectly blending the sound of the various drivers into a sonically seamless, musically and cinematically coherent whole. Our complex and sophisticated Linkwitz-Riley designs, which utilize the finest components, are masterpieces of electrical engineering. They are differential crossovers which equalize the front and rear drivers separately for both linear frequency and phase response of their summed output. Also included are advanced technology Zobel Networks which provide a more stable load for your amplifier. This makes the speaker easier to drive, which results in smooth, more natural sound. In addition, the electronic crossovers in the subwoofer modules work together with the Linkwitz-Riley networks to perfectly blend the subwoofers with the bipolar arrays. The result is a symphony of sonic perfection that completely preserves the phase coherence, transient response and dynamic integrity of the original signal.
User-Friendly Bipolar SuperTowers Will Sound Perfect in Your Home
Definitive SuperTowers are easy to hook up to your system, simple to place and flexible in terms of room positioning. They are engineered to be located as close as 4" or as far from the wall as you would like. The mirror-imaged side-mounted subwoofers can face either toward or away from each other for even greater flexibility and room tuning ability. The bipolar SuperTowers are very efficient which allows them to be used with virtually any receiver or amplifier and are of such high quality that they allow you to appreciate all the subtle excellence of the world's finest electronics. Since the subwoofers are powered, the speakers are that much easier amplifiers to drive so you are not forced to spend a huge amount for ultra high power electronics to get superb, high output, high definition sound.
You can hook them up and achieve exceptional performance as simply as running one set of speaker wires from your amplifier or receiver. And for ultimate performance, you can bi-wire the mid- and high-frequency section of BP7000SC. Finally, you can separately adjust the powered subwoofers to compensate for room acoustics and speaker placement as well as to achieve your personal sonic preferences.

"Right out of the box and with the first few notes and no extended hours of room positioning I have been impressed with greatness."
I have been an audiophile since 1968 (38 years). During that time I have owned 26 pairs of loudspeakers, here are but a few: Ohm F's, Avalon Ascent MkII's, Koss Model One Electrostatics, Carver Amazing Loudspeaker(original with gold ribbon), AR LST's(Acoustic Research), Magneplanar Tympani IIIA's, "4" Advent Loudspeakers(original Advents), "4" Bose 901 Series VI, other brands include Canton, Definitive Technology (18" powered sub), Velodyne 18" powered sub, plus 17 other highly regarded speaker systems.
The first five loudspeakers on this list are my personal favorites of all time. I will now have to add the BP7000sc's to this list, there are now six on that list. Right out of the box and with the first few notes and no extended hours of room positioning I have been impressed with greatness. I am convinced you have created a classic, thank you for designing such a wonderful product!!!
"Thank you Def Tech!"
I just bought a set of 7000SCs, a CLR3000 and 2 BPVXs. WOW I can't even belief these things. It has took me a process of four and a half years to buy my speakers. I have looked at everything on the market in the price from $2000 to $30,000 a set. Even at $30,000 these Def Techs would be worth it. You guys have done your home work. With just my Denon 3806 AVR pushing this set the sound is unreal. Then I hooked up my Parasound at 250 watts a channel and I can say for sure that here in the foot hills where I live the hills are alive with the sound of music and movies. Anyone who is looking for music or movie speaker should stop and take a real hard look Definitives, then go no further and buy right then! Music is awesome, home theater is moving, the lows are clean and low, the mids and highs are unreal with clarity. Once again all I can say is THANK YOU!!!
"Love the things"
[I] decided to buy BP7000SC on reading reviews, none [were] available to listen to, [I've] never done this before. Hooked them up to my pre amp and Krell fpb350 monoblocks. Wife and I are happy. So I ordered a set of 7004, 2300 and surrounds (don't recall number), hooked them to Rotel 1066 and 1095 amps, happy again. Love the things. By the way I'm 63 and it's taken a long time to be this impressed with sound.
"Wow! ... awesome ... beyond words"
I owned an NHT speaker system (5 NHT SuperZero + 1 SW2P Subwoofer) for the last 10 years. It was my first step into the audiophile world, and I thought they sounded great
I purchased my Definitives in February of 2005. At the heart of the system are the BP7000SCs, complemented by the CLR3000, 4 BPVX's, and the ProSub 200TL. For equipment I have a McIntosh MC352 2 channel amp, a Anthem MCA 5 channel surround amp, a Anthem AVM 30 processor, a Musical Fidelity A308 CD player, and a Denon DVD3910 DVD player. After 2 plus years of listening my system sounds better than it did out of the box. When either critically listening in stereo or watching a movie the system is simply breathtaking. The soundstage can be compared to the Wilsons at a fraction of the price. The weak link is the ProSub 200TL. After speaking with Chet today I will be upgrading to the SuperCube Reference to compliment the BP7000SC's. I am still very excited and enthusiastic about my system. I would purchase it again in a heartbeat!!!
"In my 39 years as an audiophile I can not remember a loudspeaker so competent in every area of performance..."
I have written to Definitive before, about a year ago soon after purchasing my new BP7000SCs and it seems that I can't hold back spreading the word about Definitive! I had mentioned a year ago that the BP7000SC was one of my top six favorite transducers of all time; I will now have to modify that list to include only a list of "ONE", the BP7000SC!! In my 39 years as an audiophile I can not remember a loudspeaker so competent in every area of performance particularly germane to the critical listener.
The BP7000SC will deliver what is needed when it is needed and in great quantity when great quantity is called for. I have been impressed by the sound quality of many loudspeakers over the years, but with the BP7000SC I have ceased to be enamored with the capabilities and qualities of the speaker and simply enjoy the musical presentation. I feel somewhat guilty that I paid only $5,000.00 for this high-end product.
I would suggest to others who may not have auditioned the Definitive line of fantastic transducers to do themselves a favor and do so!! Do not be afraid to compare them the most highly regarded products on the market, trust me I have!
"The powered subs create a presence that brings the soul of the artist right into the room"
Whether it's classical, rock, jazz or anything in between, the BP7000SCs reproduce sound the way a speaker should. The crossover frequencies seem to generate the maximum fidelity from each individual speaker inside the cabinet. The powered subs create a presence that brings the soul of the artist right into the room. Invite your friends over and ask them to bring their favorite CD. Watch how they react when, for the first time, they hear subtle sounds they never knew existed before. Go shop ... but don't buy until you listen to the BP7000SCs.
"These speakers, in my opinion, have one very strong point which makes them unique ... the crossover point between the subwoofer and the rest of the lower end of the sound spectrum. It is perfect!"
I have just taken delivery of a pair of Def Tech BP7000SC speakers and have integrated them into my Home Theater system (Marantz DV 8300 CD/DVD/SACD/DVD Audio player, Adcom GTP 830 Pre/pro. feeding a Cinepro 3K6 power amp; this is a six channel power amp, but I have it configured to run in the "bridged" mode giving the front three channels 700 Watts per channel! The rear [surround] speakers are driven by a Yamaha MX-1000U power amp, 250 Watts per channel; my center channel speaker is a Def Tech C/L/R/3000; my surrounds are now Def Tech 2006s, which used to be my left/right/front speakers until the arrival of the BP7000SC speakers; my subwoofer was a Bag-End ELF 1800... My display is a Toshiba 65HX93 HD). I listen mainly to classical music and action movies, and I like it loud.
The BP7000SC reproduces EVERYTHING as near to perfect as I could hope for. The strings sound like strings, flutes sound like flutes, bass drums sound like bass drums, organs sound like organs, etc. These speakers, in my opinion, have one very strong point which makes them unique to any other speaker or subwoofer I have heard (and I have heard a lot) and that is the crossover point between the subwoofer and the rest of the lower end of the sound spectrum: it is perfect!
ALL other subwoofers that I have heard or owned have had the flaw of producing "noise" when they weren't supposed to. This is most often and very irritatingly heard in the double-bass strings of a symphony orchestra. It makes them sound "muddy." Not so with the BP7000SC. My favorite "showpiece" is the cannon shots in GODS AND GENERALS, during the battle at Manassas Junction sequence. WOW!
I think these speakers are well worth the money. I can't imagine anyone not liking them.
"Everyone loves the sound of the Def Techs"
I originally bought a pair of BP7002 bi-polars coupled to an old 200 watt yamaha tube power amp and natural sound preamp. The sound was unbelievable, in fact when I sold my house in 2006 the new owner insisted the system stayed ( for 5K he got it). Little did I know what the BP7000SC's were capable of. In June of 2007 I purchased a pair along with 2 JC1 parasound Halo power amps (mono'ed) and a J2 preamp. Up until 3 weeks ago I had MP3 music going through the system. I have recently added an Olive 4hd and loaded in over 500 CD's. Last weekend I had a few friends over and one of them requested The Who (Who are You). I think we got a little carried away. We had 32 14" tiles literally ripped off the floor. What a trip. Everyone loves the sound of the Def Techs, even my best friend who is now selling his Wilson's.
"Great job Def Tech. I am a customer for life!"
I got the BP7000Sc and initially was troubled with the sound. This was because I own several Definitive Technology speakers (BP7002's, BP10B's, BP8B's, Mythos ST's, Mythos 1's, Super Cube Reference and CLR 2300's. The BP7000SC did not sound as exciting and 'sweet' like my other floor standing speakers. So, knowing Def Tech's great reputation, I said let me play around with this speaker and see. First of all the hook up is very important. Because of the bi-wiring connection you have to plug the cable in the bottom jack if you are not using bi-wire set-up. This sounded better but was still not sounding sweet. So I got some high end speaker cables and wow! The speaker now was superior to my other Def Techs. The separation of treble , mids and bass was clear and I could now clearly hear details I never heard before. This speaker reproduces the sound as it receives it without any colorations. It accurately reproduces the sound so you get it like it was produced. Some speakers sound the same no matter the source. Not so with the BP7000's. Another thing is that the Bass is very tight. No boomy stuff from these 14's. But, you can feel the heavy hiiting, it's like you are at the disco. You can actually throw parties with these mammoths. I also positioned the speakers about 18 inches from the back walls angled in to the listener. I did not develop any listener fatigue. I found that I was listening to entire CD's which prior to I was only listening to my favourites. Every song sounded good and each had its own sound. The trebles, timbrals or high pitch stuff comes in when called upon and the voices are clear and audible. I am now thinking of getting the CLR3000 to timber match the Towers. Also I changed my black end caps to cherry and the speakers look really attractive to boot! Great job Def Tech. I am a customer for life!
These are truely amaizing. I have them hooked up with two amps on each chanel (as my amps only put out 150 watts each) with CS-8040HD and if I close my eyes I can't tell where the speakers are, they blend seamlessly. The Bass is almost overwhelming (glad they have independant subwoofer volume controls).
