| 400 GMF Bass drive unit. |
|
 |
This low register loudspeaker of high efficiency (96 dB) uses the same moving element as 400-2000. Its difference is the magnet and the field plate ( ferrite of 220 mm instead of Alnico ). These qualities enable him to be directly coupled with our 1 inch horn.
It can be used in a bassreflex or jensen, crossed with 500Hz, the response curve will be linear with ± 2 dB from 40 Hz until the final frequency of 1 inch driver. It can be used perfectly for low register (symmetrical load). |
