Audison Thesis THX 3
Call for Price
THX 3 is a crossover designed for a full range three-way system with TH 1.5 violino, TH 3.0 voce and TH 6.5 sax. Constructed in a mirrored stereo configuration, it reduces overall dimensions, while making adjustments easier to perform. The most original characteristic is the "Open Design": the possibility to modify the electrical circuits, to change all of the settings that affect the acoustic results, adapting it to personal taste.
The THX crossover mother board is designed for absolute customization. As a continued open project, the user can: select the power connection mode for Bi-Wiring when used as a passive multi-amplified system; adjust the output level as well as the cut-off frequency of every single speaker in the system; define the filter cut-off slope as well as the Q (quality factor) at the crossover frequency; add notch filters to match the system to the vehicles acoustics.
Supplied with the product is a Tuning Kit: it contains all of the additional components required for the customization.
A Thesis system is an exclusive system; if used with a THX crossover, it can achieve a unique sound, everywhere, for everyone.
