135 LB
Full range driver unit
The 135 LB is a real full range functioning without bicone. Resulting from the control of the treatment of membrane of the Supravox laboratory the response curve of this membrane extends until 18kHz. optimization from the couple membrane/bobine made it possible to gain in speed of membrane and of sensitivity while pushing back until the limit of audible the high cut of the transducer. These parameters make of it a high speaker bafflable in volumes even more reduced than its precedent. In the Supravox column dedicated to 13 cm its answer is stable with +/- 3 dB of 60Hz with 18 Khz. 13 cm has to privilege for the ones in love with a clear and precise medium.
