The SB Acoustics SB34NRXL75-8 is a 12 inch 8 ohm woofer / bass speaker featuring a Norex cone, a large high power motor system and a vented cast aluminium chassis. Norex is a proprietary paper based material comprised of wood pulp and selected natural fibres blended for an optimally strong but lightweight cone that gives extended pistonic action.
Also available in 6 ohms: SB34NRX75-6 and a high Qts 16 ohm version: SB34NRX75-16.
Hard paper cone for improved piston operation (made in-house).
Large motor system with under-cut pole piece and dual shorting rings.
Vented pole piece for minimum compression.
Vented cast aluminium chassis for optimum strength and low compression.
3″ copper voice coil for improved power handling.
Long life silver lead wires.
Low damping rubber surround for improved dynamic linearity.
Non-conducting fibre glass voice coil former for minimum damping.
Optimised for vented enclosure.
