SUB T-40

Characteristics and sound properties

The SUB T-40 subwoofer is a completely uncompromisingly good vented system for use in an active installation and complements the bass range of multi-channel systems. The cube-like cabinet with an outer edge of 63 cm and sophisticated inner reinforcements has a total volume of no less than 200 litres!!! The short sides and damping of the cabinet combine to eliminate standing waves within the scope of application of the speaker. If required, the T-40 can also be supplemented with an active subwoofermodule. The driver used is the TIW 400 8 Ohm, for which a compensating magnet is available to shield off unwanted magnetic interference. The 15" speakers mounted in this special cabinet construction with its extremely large bass tunnel enable the lowest frequency bass to be reproduced without any distortion and attains unbelievably low frequency extremes of 25 Hz. Between 30 Hz and 200 Hz, this subwoofer produces a perfectly linear frequency response, which, in conjunction with the Butterworth characteristics attained and a realistically distortion-free sound pressureof over 105 dB at 30 Hz, fulfils the THX® requirements. Combined with an active filter, the required cut-off frequency and filter characteristics can be exactly pre-set. The maximum sound pressure of the SUB T-40 is 114 dB. If set up in the corners of the room, an additional 9 dB can be added to the rated maximum.

The SUB T-40 will enable you to reproduce the lowest bass frequencies at high output levels and with no loss. The extreme cabinet stiffeners guarantee reduced resonance operation with clear-cut, powerful bass that you not only hear but feel as well. This subwoofer is the perfect choice if you want to feel the acoustic effects realistically - as if you were there!
