Product Sheet

2000 Series
Driver units SUPRAVOX series 2000 are been driven by engine alnico.


This low register driver unit of high efficiency (97 dB) offers a low register quick, deep and very pleasant to listening. Its exponential cone ensures you a broad bandwidth with a natural cut at 4000 Hz without accidents in run-out.

Its engine made up of a ring of 3.5 kg of Alnico makes it possible to obtain the field necessary to reach a such efficiency.

These qualities enable him to be directly coupled with an 1 inch horn. In a bassreflex box or jensen, crossed with 500Hz, the response curve will be right with ± 2 dB from 40 Hz until the final frequency of engine 1 inch.

Frequency response 200 Hz to 20 kHz in the axis


Frequency response 200 Hz to 20 kHz at 30°


Frequency response 200 Hz to 20 kHz at 60°


Nearfield frequency response.
