CSX 217 H
217 WR 33 102 SD 4L AL 8 ohm    -    Order ID: 850136

High-end woofer with a large four layer voice coil and heavy magnet. Well suited for reflex constructions where the driver due to a low resonance frequency will produce a deep and dry bass. Excellent midrange response makes this unit very easy to filter. In fact, the driver can be used in a 2-way system (with a cross-over frequency at 3 KHz).
