## Description

Product Description          Floor-standing bipolar SuperTower loudspeaker with built-in powered subwoofer             From the Manufacturer          Movies and music are reproduced with unequaled purity, transparency and lifelike realism. The elegant, slender BP-8040ST SuperTowers from Definitive Technology offer a huge natural soundstage with a three-dimensional arc that recreates the illusion of live music or cinematic action being performed live in your room. This combination of high resolution, magnificent sound-staging awesome bass and explosive impact envelops you in the ultimate listening experience. Bipolar technology creates a huge, 3D soundstage for every listener View largerA Legend RebornDefinitive Technology pioneered the concept of "powered towers" by incorporating powered subwoofers into Bipolar floor-standing speakers, dubbing them "SuperTowers." The BP-8040ST is a third generation BP SuperTower and makes use of a new patent-pending approach to bipolar speaker design called Forward Focused Bipolar Array. The BP-8040ST SuperTower is the crowning achievement of over 20 years of research and development to create the perfect balance of style, convenience, and performance in a floor-standing loudspeaker. Achieve lightning-fast, earthshaking bass with built-in SuperCube technology The built-in digital amplifier with Digital Signal Processing achieves distortion free bass. View largerThe Most Advanced Technologies for the Most Advanced PerformanceThe BP-8040ST delivers a combination of Forward Focused Bipolar Array technology for rich life-like, room-filling, three-dimensional sound, built-in SuperCube technology powered subwoofers for lightning-fast, earthshaking bass, and the latest generation of patented Balanced Double Surround System (BDSS) midrange drivers--all housed in a rock-solid, attractive enclosure.Bipolar Technology Brings Performances to Life in Your HomeWith bipolar speaker technology, each speaker incorporates two sets of drivers--one facing forward and the other facing to the rear--so that the speakers radiate sound both forward and rearward, just as sound is produced in real life. Forward Focused Bipolar Array technology is Definitive's patent-pending improvement to the original Bipolar design. It's a new ground-breaking technology that provides you with a lifelike balance of early-arrival sound from the front facing drivers and reflected delayed sound from the rear drivers for a lush, three-dimensional soundstage. This combination creates a huge soundfield which is rich, warm, ultra clear and vibrantly alive for every listener in your room. The BP-8040's built-in subs will rock your world The BP-8040's driver array creates rich, warm, and ultra-clear sound for every listener Solidly built enclosure reduced unwanted vibration (dampening material omitted from illustrations for clarity) The Subwoofer System Will Rock Your WorldThe dual built-in 8" powered subwoofers achieve dramatically better blending, integration and timbre accuracy than could ever be achieved with separate subs. The brawny 300-watt Class D amplifier features an integrated Digital Signal Processor (DSP) that equalizes the woofer system to extend and smooth the bass response for seamless high performance. The bottom line is the BP-8040ST's bass will rock your world like no other speaker anywhere near its price and size.Why Built-In Powered Subwoofers Are Better Than Separate SubsBesides eliminating the need for a floor space-hogging separate subwoofer, integrated subs offer dramatic performance benefits. Besides having simply more bass output, two subwoofers in the room reduce "standing wave" room resonances that create bass "dead zones" in the room. With two ST-8040STs you'll enjoy high impact bass throughout the room.Patented Technology Delivers High Definition Mids and Highs Each BP-8040ST features a D'Appolito front array consisting of two cast-basket 3-1/2" second generation BDSS midrange drivers surrounding a 1" pure aluminum dome tweeter housed in an acoustically isolated sealed enclosure. The drivers feature Definitive's patented Balanced Double Surround System (BDSS) technology that supports the speaker cone at both the inner and outer edges allowing longer, more linear excursion for greater clarity and finely textured inner detail.A new patent pending Linear Response Waveguide smoothes off-axis frequency response and disperses sound over a wider area for crystal clear intelligibility for every listener in the room. The tweeter is a pure aluminum dome, which has been heat-treated to relax the crystal structure and then coated with a ceramic to produce extended highs that reveal nuance and shimmer without a trace of edginess. The rear array uses a single identical BDSS driver and the same 1" aluminum dome tweeter as used in the front array. Like the front array, the rear array is housed in a separate sealed MDF enclosure to isolate the midrange drivers from the woofers' influence.Solidly Built, Resonance-Free EnclosureThe tapered front of the enclosure serves to make it appear slimmer while also enhancing sound quality by minimizing cabinet diffraction distortion. The decorative high gloss end cap and bottom panel add elegance to the matte black tower the way satin piping adds dash to a tuxedo. Each BP-8040ST occupies a mere 1 square feet of floor-space (including stabilizer feet), leaving plenty of room for furnishings.But the enclosure's most important job is to be totally inert and resonance free so as not to color the sound. A second layer of heavy MDF inside the cabinet prevents the drivers from imparting vibration to the rest of the enclosure. The sealed midrange enclosures also serve to provide bracing for the side walls while MDF cross braces near the woofer further stiffen the system.Technical SpecificationsDimensions (cabinet only, no stablizer feet): 39" H x 5-5/8" W x 11-5/8" D (9.1cm H x 14.2cm W x 29.4cm D)Dimensions (with stabilizer feet): 39" H x 10-3/4" W x 11-5/8" D (99.1cm H x 27.2cm W x 29.4cm D)Driver complement: 3 each 3-1/2" (9cm) BDSS midrange drivers, 2 each 1" (25mm) aluminum dome tweeters, 1 each 8" (20cm) active subwoofer driver pressure coupled to 2 each 8" (20cm) Low-bass radiatorsFrequency response: 25Hz - 30kHzSensitivity: 92dBNominal Impedance: 8 OhmsA/V Receiver Crossover Setting: Large, full bandwidthInternal amplifier power: 300 WattsAuto On / Off: Signal SensingPower Requirements: 110 volts A/C (product not available outside of USA, Canada and Latin America)Inputs: One pair of 5 way binding posts; One LFE input (optional)Accessories: Stabilizer feet; carpet spikes, hard floor glidesProduct weight: 40 lbs.

## Questions & Answers

**Q: Would these be good as surround speakers?  I have the 7001 for the fronts**
A: yes they would . expnisive . but good . I use the 8040 surrounds as they throw sound signels around more . you could and can use the as surround and side surround channels .

**Q: can the atmos speakers be added to these?**
A: Well, i was wrong, if you look.up the A90 speaker it sayes it qorks on the 8040.

**Q: Is an av receiver that has 165 max watts per channel sufficient for these speakers? or should i be getting a receiver that can do 300 watts?**
A: 165 watts per channel is more than enough.  These speakers are Powered Towers.  Meaning, the woofers are driven by the speakers own internal amp.  Your receiver will only be powering the midrange and high frequency drivers and those drivers do not consume much power at all.

**Q: I have a x2300 receiver which has 95 watts per channel .is that sufficient power ? Also I am using lfe connection for subs**
A: 95 WPC is more than sufficient.  These are Powered Towers.  Your receiver will only be driving the mids and tweeters.  The woofers have their own built-in 300 watt amps.  If you have separate subs set your receiver LFE crossover to 50hz and let your subs handle the lowest bass freqs. and let the towers handle the upper bass freqs.

    Great sound!  Great speakers!
  

*by L***R on Reviewed in the United States on February 20, 2011*

I purchased these recently to replace a pair of Polk TSI series speakers and a Klipsch SW-450 subwoofer. While this setup was pretty darn good, I didn't like the size of the subwoofer taking up so much floor space and although the sub was very powerful, I thought the sound quality was muddy when playing music. Being a Bass player, I love low frequencies and wall shaking bass, but when listening to music, I like to hear note definitions of the Bass guitars and this sub didn't produce a clear tone, just a powerful low end blur. Taking a chance with the Definitive Tech 8040's right away I noticed the Bass tones on music playback was more defined. Plus the 8040's give you 2 subs without taking up extra floor space! Even better is the fact you don't have to worry about phase problems and cross-over settings, these are factory calibrated and matched precisely for these speakers, just turn up the amp on the rear of the speaker for as much bass response as you desire. I only turn them up to 1:00 and that's plenty.You have your choice of hooking these up to your receivers LFE jack so you can set up the some of the crossover amounts within your receiver yourself or I prefer to just run speaker wires to them and use the speakers internal crossover. As for watching movies, these sound great with plenty of low end rumble and realism due to the bi-polar design of the mid-woofers and tweeters. Just be sure to leave some room between the rear wall and the speakers to let them breathe. I keep mine about 2 feet away. About the only thing I would change in the design would be to make separate right and left speaker cabs with the subwoofer on corresponding sides. As it is, Both subwoofers are on the same side only. Bass frequencies tend to be somewhat omni-directional but with these, one subwoofer is facing directly at my large TV stand while the other faces outward in my living room. So in essence with the sub facing my TV stand, some of the the sound waves are being blocked or diverted because of this. I have recently spread the speakers further apart to compensate best I can in my limited living room. All in all my search for the perfect floor speakers are done! I also did away with my cheap little rear surrounds and now I'm using my former main floor Polk TSI series speakers for my rear surrounds and sold the Klipsch SW-450! While these speakers are pricey, consider the cost of buying 2 High quality tower speakers and 2 subwoofers, and you still wouldn't have the realism the bi-polar design offers not to mention a lot of floor space used up for all those speakers if you have a small to medium sized living room.  Next consideration would be the Definitive Tech's powered center channel speaker...hmm

    BP8040ST - well-rounded performers!
  

*by R***M on Reviewed in the United States on May 9, 2016*

I shopped many brands and was able to audition only a couple of other similarly priced towers.  Unfortunately, I was not able to audition the Definitive products, but on a whim (and after reading several great reviews), I purchased these.My first impression was good.  It was not until the family left the house and I was able to play around with different types of music at variable volume levels and bass levels that I became VERY impressed.My Marantz home AV receiver does not push a tremendous amount of power, and my previous speakers (B&W iSeries Towers) never really sounded all that good on this AV setup.  They just needed more power.  Enter the Def Tech BP SuperTowers.  Having the on-board 300w amps with integrated 8" subs is perfect for anyone running a receiver rather than a high-power 2-channel system.  The bass response is outstanding - especially at lower volume levels.  You still hear full-spectrum sound without in-your-face volume.  Having said that, when you want some in-your-face type of volume, the bass balance and imaging from the bi-polar design is appreciably different and superior to others I shopped or to what I was ever able to get out of my B&Ws.  I was not sure what to expect with the Bi-Polar design, but the highs are somehow a bit softer seeming and overall, rich/smooth.I think there may be better options if you are looking for 2-Channel listening and you already have a high-power amp, but I highly recommend these for anyone looking to improve on an AV setup...  Amazing bass without having to add a sub and great sound/efficiency - all in a very attractive package!

    Big sound
  

*by A***M on Reviewed in the United States on March 6, 2012*

After relinquishing a pair of large Synergistics speakers from college days after getting married, I switched to Cambridge Soundworks Ensemble II with passive subwoofer. While they were adequate for a small room with hardwood floors, I found the lack of bass noticable in a carpeted room with vaulted ceilings. After reading a number of reviews of various speakers and considering Cerwin Vega, JBL, Klipsch, Paradigm, and Polk, I stumbled accross these. I was initially concerned that they might not produce enough sound but did not want to pay the additional expense of the 8060s. I was able to get these at 600 each instead of 800 through an Amazon seller. They are more than adequate for a large room. Some reviewers complained that they do not come as a left and right. But this actually does not seem to matter. The single most striking thing I found was that I no longer notice a right and left channel. The sound is dispersed over a wide area but with such accuracy that I can understand the words of songs that sounded mumbled on other speakers. I listen with the sub at midway where manufacturer recommends you start and even that can be a bit too much at higher volumes if you live in an apartment. Given the clarity, I will probably replace my center channel with the CS 8040 when budget allows.
