257 H 257 SWR 39 115 SDX 4L AL 8 ohm - Order ID: 850146 High-end 10" woofer with a 5 layer "Sandwich" cone, extra heavy magnet, extra long 4 layer coil and distortion killer shortcirquit ring in the magnet system. This gives exceptionally good linearity and very deep and clean bass. Also, remark the very smooth response.This CSX 10" woofer is recommended for very versatile use in closed as well as vented boxes. In a reflex box of 100 ltrs. with tunings around 23 Hz it keeps level down to 30 Hz. A remarkable characteristic is the very robust extra thick iron plate basket with a nice structure lackering. |
