Product information "SB Acoustics SB34SWNRX-S75-6"
The SB Acoustics SB34WNRX-S75-6 12" woofer uses a large 3" voice coil on a cast aluminium chassis. Hard Paper proprietary cone materials made in-house for consistency. Low damping SBR rubber surround with high exertion and resilience. Open structure cast frame for reduced reflections and compression. Aluminium alloy for light weight, non-magnetic and extra rigidity.
Features:
Hard paper cone for improved piston operation (made in-house)
Vented pole piece for minimum compression
Vented cast aluminum chassis for optimum strength and low compression
3 copper voice coil (4-layer) for improved power handling
Long life silver lead wires
Low damping medium hardness rubber surround for improved linearity and power handling
Non-conducting fiber glass voice coil former for minimum damping
