EXC Bass drive unit. |
|
 |
A high low register speaker of audiophile quality: the 400-2000 EXC offers very high quality of answer (speed and broad band) because it is built goshawks of the same membrane as 400-2000. Its advantage remains open the possibility of adjustment of these parameters thanks to a powerful engine electromagnetic. Adaptable of this fact to many enclosures, it requires an external power (ideal of 10 with 14V for 5A).
