| 285-2000
Bass medium drive unit. |
|
 |
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. |
