Definitive Technology's BP8 is a revolutionary audiophile-engineered, designer-styled loudspeaker intended for musical reproduction and home theater systems of the highest quality. This full-range bipolar (front and rear) radiating system combines the lush spacious soundstaging, lifelike depth-of-field, razor-sharp resolution and pinpoint imaging of the finest dipolar panel loudspeakers with the extended bass response, high-efficiency, wide dynamic range and easy-to-position convenience of the best conventional box systems.

  • newegg Audiophile Performance, Designer Styling, and Unmatched Value The spectacular three-dimensional imaging, awesome deep bass response and silky smooth high definition linearity of the Definitive Technology BP8B are the result of a myriad of technological advancements and breakthroughs (including the latest state-of-the-art components and technology developed for Definitive’s flagship BP7000 Series loudspeakers) which have been combined to create unmatched instruments for the reproduction of music or movies in your home. They truly recreate reality that totally suspends disbelief.
  • newegg The Sonic Superiority of Definitive's Bipolar Loudspeakers Definitive Technology's speakers radiate the full sonic spectrum both forward and rearward in an omni-directional pattern, exactly as sound is produced in real life. This unique technology provides you with a lifelike balance of early-arrival sound information. Bipolar technology assures a superb panorama of lifelike sound for every listener wherever they are in the room. 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. This combination of high resolution, magnificent sound-staging awesome bass and explosive impact literally envelops you in what is absolutely the ultimate listening experience.
  • newegg Monocoque, Non-Resonant, Low-Diffraction Cabinets The design of the BP8B reduces diffraction to an absolute minimum by flush mounting drivers on extremely narrow baffles with radial edges, which are covered by a frameless grille "sock." In addition, the resonant vibration of a loudspeaker's cabinet walls and baffles can also impart unwanted coloration. The Definitives' monocoque cabinets are constructed of high-density medite with 1" thick front and rear baffles, foam dampening pads and internal braces. This virtually eliminates resonant cabinet coloration which could otherwise interfere with the pure sound produced by our high definition drivers. The BP8B also includes an additional divider/brace panel separating the front and rear drivers.
  • newegg Multiple High-Definition Cast-Magnesium Basket Drivers The BP8B utilizes two high definition cast basket bass/midrange drivers (the same as used in Definitive’s flagship BP7000 Series) for significant performance advantages in the areas of bass reproduction, lifelike midrange clarity and dynamic range. These sophisticated bass/midrange drivers incorporate deeply drawn mineral-filled polymer cones, combined with butyl rubber surrounds and dustcaps, 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 bass response. In addition, they are assembled utilizing an aerodynamically designed, magnetically inert, cast-magnesium basket to minimize internal reflections off the back of the cone and preserve structural and magnetic integrity under all conditions.
  • newegg Moving Coil Pure Aluminum Dome Tweeters The moving coil dome tweeters Definitive developed for the top-of-the-line BP7000 Series are used in the BP8B. They utilize a specially annealed pure aluminum 1-inch dome, suspended by a silk surround and acoustically loaded by a precisely configured phase plug/lens, engineered to assure perfectly controlled, absolutely linear movement. This results in velvety smooth extended response (beyond 30 kHz), greatly reduced distortion, improved transient response, wider dispersion and notably higher definition. Magnetic fluid damping is incorporated for ultra high power handling.
  • newegg Phase-Coherent Linkwitz-Riley Crossover Networks The crossover network of a loudspeaker is the real heart of the system, as it is responsible for perfectly blending together the sound of the various drivers into a musically seamless whole. The sophisticated Linkwitz-Riley design used in the BP8B equalizes the drivers for linear phase and frequency response. This preserves the phase coherence, transient response and dynamic integrity of the signal for absolutely lifelike music and home theater reproduction in your home.

5 out of 5 eggsBP8B

Pros: Looking to replace an aging speaker system, came across these on the Egg for 199 each.. So i bought 2. liked them so much i bought 3 Mythos Two's to complete my 5.2 setup. I have never heard music or movies sound so good. The detail is incredible, precise and accurate. Paired with Def Tech. Pro 1000 and acoustech PL-200 subs, Its all real good.

Cons: None what so ever.

Other Thoughts: Better get them while they last, If I could talk my wife into it, I would be the proud owner of 2 more for a 7.2 setup!

5 out of 5 eggsFine-sounding Speakers

Pros: Plenty of detail without harshness
Enough bass for most music (needs a sub for home theater)
Spacious and room-filling, if the room's not too big
Overall smooth, accurate, neutral sound
Fairly efficient, not power-hungry

Cons: Shouldn't be placed near walls; bass extension is more like a good bookshelf speaker than a floorstander

Other Thoughts: At their NewEgg sale price, "bargain" doesn't begin to describe the BP8b. Utilizing two of the same bass/mid drivers and two of the same tweeters as found in Definitive's legendary BP7000 (#19 on Audiophile Review's "Top 25 Audiophile Speakers of All Time" list), this technology may be a few years old but it's still totally competitive. After all, speakers haven't changed all that much.

By themselves, these speakers are like really good bookshelf speakers mounted on stands, with the added dimension of the bipolar design's spacious imaging plus the more robust dynamics afforded by a larger cabinet. Don't expect useful bass below 40Hz, and don't expect to fill very large rooms. But if you're looking to pay under four bills for your mains in an HT system where the seats are within 10-12 feet of the screen, or you are building a music-only stereo system, wait for a sale and grab a pair of these.

2 out of 5 eggsAvoid buying

Pros: Looks nice

Cons: Weak output, a reason why they were discontinued, even sounds bad with a powered subwoofer. So inconvenient to have to plug the speaker wires into the bottom.

Other Thoughts: Just got the speakers today. One worked and the other didn't. One of the reviewers said they had to do some wiring to fix theirs. I was not prepared to do that but I couldn't beat the price. Since one was defective, I was only able to test one of them. From what I heard I was not impressed. These were meant to replace my Polk RT2000Ps. Not even able to compare. I thought the whole bidirectional polar thing was supposed to wow me. Instead, I heard a tiny little speaker trying its best to put sound out. I figure since I had to return the defective one I might as well return the other one and ask for a refund.

5 out of 5 eggsDef Tech BP8B

Pros: Crystal clear highs with adequate lows,5yr warranty and at 199.00 a piece, I had to have a set,They sound Fantastic right out of the box,Def Tech says 20-40 hrs break in and at the 10 hr mark,I could hear a difference,A more enveloping soundfield,These are wonderful speakers.

Cons: None

Other Thoughts: I have these up front,A CS8040HD center,Mythos Gems for rear surrounds and a Yamaha YSW216 sub, wired to a Yamaha RX-V375, Speakers are set to small and crossed over @80, with the sub gain @ 50% in a 14x16x8 ft room and it sounds great for HT,I have heard better for music but not for the money.

4 out of 5 eggsGreat Speakers for the price

Pros: Small footprint, good sensitivity, wide soundstage, good mids & highs. Can handle high power amps in the 200 - 300 watts range with ease. Gives you solid mid-bass for the speaker design.

Cons: Placements of speakers is a concern, lacking in deep low bass.

Other Thoughts: It's a good pair of speakers for Home Theatre & audio use. Must have good placements for these Bi-polar designs.

5 out of 5 eggsAwesome speakers

Pros: These speakers are some of the best speakers I have heard. I questioned the bi-polar aspect of the speakers, but now I am a believer. These have a very balanced sound, slightly on the bright side, but I like it that way. Very clear and open sounding. Bass response is good for a 5.25. Never boomy always accurate. They have their limits, but will go pretty loud without distortion. They are small and good looking, no fake wood vinyl wrap stuff here. They are heavy for such a small speaker(good construction) and being small adds to the placement options. you can have these 6 or 8 inches from a wall and still stick out less than other bulky speakers.

Cons: Nothing too bad, the specs for all Definitive speakers seem to be exaggerated note that they don't give the +/- x db rating with the frequency response. The low range of these is definitely overstated just look at other speakers with 5.25 drivers, cross them over at 70 or 80 and get a good sub. They do a decent job at 2.0 channel, but you miss the extreme low frequency stuff.

The tops will fall off when you tilt them to connect the terminals on the bottom. Not able to bi amp. placement is tricky, but not as bad as some people say.

Other Thoughts: In my opinion these are the best speakers newegg sells. They usually have a great price when they are in stock. I want to buy another set for surrounds as you can place them sideways on the back wall and get good dispersion of sound.

I have these matched with a mythos 3 center, or mis matched rather. Sounds good to me, but I believe the appropriate matching center was too large and out of my price range. I believe they share the same tweeter, but the midrange drivers are a different size which gives them a slightly different tone.

Def Tech is known for their supertowers with built in subs, but I'd rather have these and a separate sub. I wish the egg had the 6.5inch woofer version, but the bottom line is these are very nice speakers.

5 out of 5 eggsAmazing Piano

Pros: Piano sounds amazing. Movies sound amazing. Bass is very good for what you pay for. The mids and highs are very, very clear. A friend with a big surround system was amazed what these did for home theater by themselves. You will hear things you have never heard before on movies you have watched a dozen times. Excellent instrument separation. Placement is important. Well worth the cost.

Cons: No built in subwoofer but what the heck do you want for this price? Not great for heavy metal music. That's because the bipolar technology isn't a 'blast at your head' technology. It's a flowing, more symphonic, more surround-type experience.

5 out of 5 eggsImpressive

Pros: Nice bass,snappy highs

Cons: Non yet.

Other Thoughts: I know it's kind of soon to post,(I just unboxed them)but,I love them already. I am running the Def Tech monitor 350's in the rear. They all sound great. I can't wait to hear what the BP8's sound like once they're broken in. I highly recommend these towers.

Cons: None that I can think of
