Product Description

Product Description

The Reference Subwoofer for Reference Systems If you are assembling a reference home theater system with a high definition video projector or monitor along with an audio system that exceeds the sound quality and sheer visceral impact of premiere movie theaters, then this is absolutely the subwoofer for you. The Reference incorporates a 14 inch SuperCube® Technology driver pressure coupled to two 14" Ultra Low Bass Radiators. The total piston area of this complement is an astonishing 460 square inches; equivalent to a 24-inch diameter woofer but with far greater speed, musicality and control than a single large diameter woofer could ever deliver. With that much moving driver area, you can fill any domestic living space with loud, visceral, deep and musical bass.Music Lovers RejoiceSubwoofer manufacturers are always talking about how "explosive" their subwoofers are (frankly so do we), but there's more to home entertainment than rocket blasts and explosions-there is music, be it in the movies you watch or the CDs you enjoy. And for music the quality of a subwoofer's performance is way more important than the quantity. The bass should be "tight," precise, and musical. Bass notes should have pitch, not just a dull thud or drone. Definitive Technology was started by and is run by music fanatics and the very first thing we do to evaluate a subwoofer prototype design is to listen to music. If a subwoofer doesn't do an exemplary job with music reproduction, it isn't a Definitive.Mas

From the Manufacturer

SuperCube: Redefining the "Low End", Affordably

The SuperCubes set new performance standards for high-output ultra-compact subwoofers. The Reference incorporates a 14" version of the 10" SuperCube Technology driver that is pressure coupled to two 14" infrasonic radiators. All this is powered by an 1800-watt class D amplifier. The result is astounding high-definition bass performance extending effortlessly down below 11 Hz. Each SuperCube Reference subwoofer has dynamic impact and output capabilities almost equivalent to that of four SuperCube subwoofers combined--plus even more low-frequency response. Slam, pace and rhythm are exemplary as is the ability to actually shake cement slab foundations. A complete complement of inputs and controls, including continuously variable level, high-pass, low-pass and phase controls, speaker and line level in and out, and LFE Direct in, are included on this surprisingly compact and stylish cube.

  • SuperCube Trinity Signature Subwoofer: The new SuperCube Trinity Signature is a very special over-the-top powered subwoofer which was originally developed for the state-of-the-art electronic organ at Trinity Church in New York (which uses a huge multiple array of Definitive bipolar towers - one for each organ pipe). It delivers outstanding low frequency performance which heretofor has not been available in such a compact enclosure. In fact, it was designed to replace 5' x 5' x 8" boxes which had previously been used in organs of this type. Capable of prodigious output (in excess of 128 db at 20 Hz and 116 db at 16 Hz in a normal room) the Signature is also quick and highly detailed. It may be used vertically or positioned on its back when custom installations call for it.

    Can hardly wait to save up more to get at least one more of these monsters!

    The robustness of the bass without overpowering the other sounds is really amazing.

    Need bass? This subwoofer DELIVERS. It's hard to believe such powerful bass comes from such a compact package. I have used it mainly for movies, but performs great for music (though most reviews I have read say it's better for movies). Have no doubt, this thing will send shock waves through the walls and your bones -- effortlessly. And with great precision. The sound is tight, smooth and just a pleasure to listen to -- and feel. Buy one and you'll be totally satisfied; buy two to eliminate all standing waves and get perfect bass throughout your listening area. I have this thing working in tandem with a Velodyne FSR-15 Servo and oh, what team they make! I have reached Bass Nirvana.

    I own four Mythos STS's,2 Mythos Gem XL's and a Mythos Ten. Which all combined puts out very very powerful and forceful amounts of bass and excellent sound quality. But I decided to get 2 of these behemoths and they are like a sleeping giants one minute they are asleep and the next they send a shock wave like a bomblast through me and my house. For music they are pretty good I give them a 7 out of 10 but for movies and video games that is where they really excel for movies and games I give them a 10 out of 10 they are unbelievable especially Blu Rays or HD DVDs. Movies and games really reach subterranean depths they can put out bass so low you can't hear a thing but you feel them shaking the earth and resonating through your body and pressurizing the entire house they truly put out more bass than anything I have felt in theaters. Sometimes the bass feels as if I am in a river stream with fast moving water all around me but it is not uncomfortable. Normally I just have the both of them at 50% gain and that is more than enough. Someone asked me why so much power and bass because with my 4 Mythos STS's and there built in amps along with my 2 Super cubes I have a total of 4,800 watts of subs, but I think it is better to have a gun and not need it than need a gun and not have it lol. But it is not all about just bass and power and volume it is about sound quality and being able to integrate them into you sound system with out overpowering the other speakers. I have had no issues doing just that. If you want to see pics of my HT setup and many many others go to "B l u r a y . c o m" my profile is Alpha Sixx.

    Great sub, but more than that, the folks at Definitive are amazing. My sub did blow the lower amp within a few weeks of heavy use, but made one quick call to Definitive and they shipped me a new lower level amp and viola, back in business. Great company.

    All of the other reviews seem to agree... This is a badasz sub. I have a B&W setup for music and a def tech system for av. This thing will do anything. Way tweaked up, it will absolutely knock all of the knickknacks off of the shelf. Properly integrated, you'll never know there is a 14" killer lying in wait. The music will just sound better. And for HT, it will probably kill your cat unless you plan differently. I'm running one and a 4000 (the ref is expensive) through a 4520 and its easy. And nice. Buy it.

    The subwoofer makes all the difference between a good theater experience and an amazing one. This subwoofer is the best I've ever had. It delivers bass that will shake your insides when it is appropriate, but it never drowns out the other sounds. The robustness of the bass without overpowering the other sounds is really amazing. I've never had home theater that sounded so natural and real.
