SuperCube® Trinity Signature
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'x5'x8'' 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.
