285-2000 Haut-parleur large bande 70W / 101dB / 8Ω - Supravox
Description

Product Sheet

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

 

On the basis of 285 GMF, we adopted the same engine as 215-2000. That enables us to obtain a low register even faster.
With weaker Qt and a more important efficiency, it is the low medium ideal in the active multichannel installations. Iit is the ideal driver unit for a low register horn.
