SB Acoustics SB34NRX75-6

SB Acoustics SB34NRX75-6 12" Woofer

The SB Acoustics SB34NRX75-6 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. Shorting Copper cap on pole piece. Non-inductive 75mm coil former.
