Definitive Technology SuperCube Trinity Signature Dual 14" black 2000W powered subwoofer

Soul-shaking bass

The 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, including 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.

Super sound from SuperCube®

Definitive's SuperCubes are a new breed of powered subwoofers which utilize unique technology and components in order to achieve state-of-the-art performance from remarkably small boxes. Remember, it is important to understand when you are evaluating the SuperCubes that you can not simply compare them to conventional subwoofers based on driver size. Because of their unique technology, the SuperCubes deliver far superior performance to conventional subwoofers which utilize drivers of 50% - 80% larger diameter.

Pure low distortion response

The cabinet of a loudspeaker plays a large part in its sonic performance. Resonance and vibration can add unwanted distortion as well as drain away important energy from the system. Definitive's subwoofers utilize monocoque cabinets, which have been specifically engineered to be totally inert and vibration free, to ensure you of absolutely pure sonic reproduction. Monocoque means that the cabinet is of a unitized construction where all panels are permanently joined together into one solid structure. The cabinet walls themselves are high-density medite fused together by space-age polymer adhesives. The front and rear baffles are extra thick and the cabinets each incorporate multiple internal braces to ensure total solidity.

Completely adjustable electronic crossovers

The sophisticated low distortion electronic crossovers incorporated in all Definitive powered subwoofers are a masterpiece of design and execution. They contain a complete range of hookups, circuitry and features which allow the subwoofers to be connected and perfectly blended with any system as well as adjusted for optimum performance in any room. All Definitive powered subwoofers have continuously adjustable low pass filter controls which allow you to choose a roll-off of from 40 to 150 Hz for the high end of the subwoofer. This unique "dual stage" roll-off is extremely quick which ensures perfect blending with your main speakers as well as no unwanted upper bass or midrange radiation from the subwoofer. This is especially important because it gives you much greater flexibility in placing your subwoofer in your room without being able to hear where it is specifically located. SuperCube® powered subwoofers also have a separate low-level direct LFE input for Dolby Digital which bypasses the crossover network. All models have a built-in speaker level high-pass crossover preset at 80 Hz (except ProSub 60 preset at 100Hz) and, of course, a precision level control allows you to perfectly adjust the volume of the subwoofer to match your system and room as well as to fulfill your own personal sonic preferences.

Full range of inputs and outputs

All Definitive powered subwoofers have a complete range of inputs, outputs and features to allow easy and effective hookup to any system either singly or in a stereo pair. Both (high) speaker level and low-level inputs are provided in case you don't have a subwoofer output. In addition, all models have a separate direct-in LFE low-level input (which bypasses the crossover network) which may be used by itself or in combination with left and right channel high- or low-level inputs for the ultimate in subwoofer flexibility and performance. With a single subwoofer, the subwoofer signal, Dolby Digital LFE signal and/or both left and right signals are sent to the subwoofer and combined via the electronic crossover into one composite signal. With stereo (two) subwoofers, the left and right signals are reproduced by their own respective subwoofer (and the LFE signal is reproduced by both). Very advanced systems may also use a separate subwoofer hooked up to the rear/side surround channels as well as one to the center channel.
