Advanced bipolar speaker technology immerses you in detailed sound

sound waves

Front and rear speaker arrays work together to create enveloping sound.

Here's how it works: direct sound from the front two midrange drivers and tweeter arrives at your ears first, to provide clear, focused imaging. That's followed by sound from the rear mid and tweeter, which is slightly delayed, to enhance spaciousness. The combination creates a lush, seamless soundstage that's more like the way we hear sounds in real life. And thanks to Definitive's Balanced Double Surround System (BDSS) drivers, your music and surround effects will sound incredibly clear, allowing you to pinpoint the soloist in a band or the direction of a jaguar's call in the jungle.

Powerful bass built right into the cabinet

At the base of the speaker is a 10" side-firing subwoofer coupled to two passive radiators. This trio creates a total surface area greater than that of a traditional 15" woofer, but with better bass control, speed, and detail than a single huge woofer could achieve. A built-in 300-watt amplifier powers the subwoofer, delivering hard-hitting bass that eliminates the need for an external sub. And because a subwoofer is built into the cabinet, bass output is already perfectly blended with the mids and the highs. All you have to do is set the bass volume to match your room and taste, then sit back and enjoy your music and movie soundtracks.

Build a complete Definitive Bipolar home theater system using perfectly matched centers (see the CS-8040HD, CS-8060HD, and CS-8080HD) and bipolar surrounds (see the SR-8040BP and SR-8080BP).

Did you know?
Your new speakers will probably sound better after several weeks of use than they do right out of the box. That's because the material surrounding the woofers will loosen up, allowing the drivers to move more fully. Definitive Technology estimates a break-in period of 24 to 48 hours of playback before the speakers will deliver optimum sound quality. For more information and helpful tips, check out this article from Definitive's website about conditioning your speakers.

Speaker Features

Speaker Features

Bipolar Design: The Definitive Technology BP-8060ST is a 3rd generation "SuperTower." This bipolar speaker contains drivers on the front and rear of the cabinet. The BP-8060ST uses a new patent-pending design called Forward Focused Bipolar Array. By radiating sound both forward and rearward, the speaker produces sound as it is in real life, with improved pinpoint localization of soloists, greater placement flexibility, and superior intelligibility.

Non-Resonant Tapered Cabinet: The BP-8060ST features a highly-engineered inert and resonance-free heavy MDF (medium-density fiberboard) cabinet to prevent coloring the sound. The front of the enclosure is tapered to make it appear slimmer. Wherever a driver is attached to the cabinet, a second layer of MDF is attached to prevent the drivers from causing vibration to the rest of the enclosure. The sealed midrange enclosures serve as braces for the side walls, while MDF cross braces near the woofer further stiffen the cabinet. The entire enclosure is wrapped in a cloth "grille sock", while the high-gloss polymer composite end-cap and bottom panel add a touch of elegance.

High-Definition Drivers: The BP-8060ST utilizes two cast-basket 4-1/2" high-definition polymer composite midrange drivers surrounding a 1" annealed Pure Aluminum dome tweeter in a D'Appolito front array. On the rear, there is a single identical 4-1/2" driver and the same 1" aluminum dome tweeter as used in the front array. The front and rear arrays are housed in separately sealed MDF enclosures to isolate the midranges from the influence of the subwoofer. The drivers feature Definitive Technology's patented 2nd-generation Balanced Double Surround System (BDSS) that supports the speaker cone at both the inner and outer edges, allowing longer, more linear excursion over a wider area. A new patent-pending Linear Response Waveguide smoothes off-axis frequency response and disperses sound over a wider area.

Built-in Powered Subwoofer: The BP-8060ST is equipped with a long-excursion, side-firing 10" subwoofer, driven by a 300-watt Class D amplifier with an integrated Digital Signal Processor. The subwoofer is pressure-coupled with two 10" Low Bass Radiators. The combination of the active subwoofer and two bass radiators gives you 29% more surface area than a single 15" woofer, but with better control, speed, and detail. The benefits of a built-in subwoofer include:

  • Eliminates the need for a separate subwoofer that takes up additional floor space.
  • More bass output from two subwoofers, compared to one.
  • Two subwoofers reduce standing wave room resonances and dead zones for more evenly distributed bass.
  • The subwoofers are perfectly integrated and blended with the mids and highs, eliminating the crossover and phase controls of a separate subwoofer.

Subwoofer Volume: The level of the subwoofer (relative to the other drivers) can be adjusted using the rotary dial on the back panel of the speaker. Once the bass level is set, the overall volume of the speaker system can be controlled by the receiver/amplifier.

Auto Power: The BP-8060ST has a special circuit that automatically turns on the amplifier when a signal is fed to the speaker. The LED on the back panel will glow when a signal is sensed and the amplifier turns on. After the signal ceases, it may take up to an hour for the amplifier to turn off. When first powering up after being unplugged, the LED will flash for about 30 seconds while the firmware is loading.

Stabilizer Feet: The speaker comes with four stabilizer feet which attach to the bottom of the cabinet, two per side, with the supplied self-tapping screws. Each foot has a threaded insert to allow you to screw in the supplied carpet spikes or smooth floor glides, depending upon the type of floor they're being placed upon. Four additional threaded inserts are provided on the bottom panel (along with 4 additional carpet spikes and floor glides) in case you decide not to use the stabilizer feet. The spikes and glides add approximately 1" to the overall height of the speaker.

Placement: The BP-8060ST Bipolar speakers have a lot of flexibility when it comes to placement and positioning. It is recommended that the speakers be placed at least 4" from a back wall, and at least 6" from a side wall. When used as left and right main speakers, you should set up the speakers and the listening position in an equilateral triangle, with the speaker cabinets turned slightly inward.


Binding Posts: The BP-8060ST is equipped with a pair of gold-plated, 5-way binding posts on the back of the cabinet to attach your receiver's speaker wire. The terminals will accept bare wire, pin connectors, spade lugs, single and dual banana plugs. Recommended amplifier power: 20 to 300 watts RMS.

LFE Input: For the powered subwoofer, the BP-8060ST has a single RCA LFE (low-frequency effects) input. Since you'll be using two speakers, you will need a Y-adapter to split the LFE output from your receiver to each subwoofer.

Wiring Options/Speaker Setup: You can connect the BP-8060ST in one of two ways, with or without the LFE connection. If you use only speaker wire, you should set the speaker setup on the receiver to "Large" and Sub to "No." If you connect the speaker with speaker wire and the LFE, the speaker setup should be "Large" and "Yes."

Note: It is recommended that you do not use the receiver's auto setup function, as it is often ineffective in setting up and adjusting speakers with built-in subwoofers.

AC Power: The speaker has an AC power input (IEC 2-prong type) on the back panel for plugging in the powered subwoofer. A 7' AC power cord is included.

I presently have def tech pro cinema 600 system and am considering get the def tech bp8060st and top firing speaker add ons to replace two of the front pro 600 to get more punch , is this advisable and should Ieliminate my sub or leave it. I also upgraded from denon ave 1615 to a new Onkyo NR -737 will make huge difference , basically saying does everything have to match by being a bipolar system ? Thanks for your help and suggestions .

You can definitely use the BP-8060ST as the front left & right speakers in your system. They will voice match well with the center and surrounds you have now. You can continue to use the subwoofer as you can always turn it down if you find you've got too much bass with the new speakers. I hope that helps!
ryan  Jan 01, 2016 (Staff)
Can I use a pair of these towers as back speakers?
joe  Dec 02, 2015

Technically I guess you could, but it would be over kill as most of the sound track is through the fronts. I paired these with the SR8040 bi polar surround speakers and the system sounds awesome.
michael  Jan 07, 2016
I am sure you can, but I would highly recommend not. Each need a power source, and sub wire. So if you use them as back speakers, then you would need (4) sub wires, as I assume you would certainly need two for the front ones. I do not think most receivers offer that many. Good luck, these are amazing front speakers! Don't forget their center speaker... probably the most important!
ruben  Dec 03, 2015
I own these, it most certainly can be used for the rear or back channel. However, this is high-powered tower with bipolar firing speakers and built in powered subs -- Which could cause a distraction with too much sound from that channel. There is a mates set of bipolar surround speakers to this serious, which are smaller but still powerful. You may consider that instead -- that's what my set up is and I'm very pleased with it.
rick  Dec 03, 2015
is it necessary to use in pair or will it be alright to use only 1pc of this tower speaker?
ronnie  Oct 20, 2014

I guess it would all depend on how you want to use it. If you are playing a stereo album or watching a movie then two towers is a must. If you like to listen to mono radio or albums then a single tower might be fine.
charles  Oct 20, 2014
I am curious why someone would ever want only one of any speaker. Speakers most of the time are sonically matched, at least for main speakers, I would want them to be the same. I am OCD enough where I want all speakers in my system to be sonically matched. But that is just me. To answer your question, of course it will work, it's just an analog signal being converted to sound, but it is far from an ideal situation.
ian  Oct 20, 2014
Ronnie it all depends on what your goal is. Anything less than stereo, with one tower youre fine.
cornell  Oct 20, 2014
These speakers are truly amazing!! One alone can likely blow you away, but for a true stereo sound, two would absolutely be needed.
ron  Oct 20, 2014
You may use it in mono with full signal played. However, if you want stereo sound you would need two, one for left and one for right channel. As an added bonus it has a built in powered sub whic can receive and filter to play the .1 channel in 2.1, 5.1, etc.
thomas  Oct 20, 2014
You can use only one at a time if need be, (which I have done) but they sound much better as a set, I suppose it would matter what you have in mind as far as your intended use, but using them as a pair gives you much fuller sound, this has been my experience. I have had mine for a year now, hooked up to a Yamaha receiver, hope this helps.
