SB, SB29NRX75-8

The SB Acoustics, SB29NRX75-8 is great 8-ohm 10″ woofer from SB Acoustics.

This is the 8-ohm version of this popular 10″ woofer.  The 8-ohm impedance makes it very useful for making a dual woofer, subwoofer which nets 4-ohm load to your amplifier.  A recent build by Javad S. uses this woofer combo in “dual opposing woofers” configuration.  The cabinet vibration reduction with this technique is amazing.

Features include –  Hard paper cone for improved piston operation (made in-house), a vented pole piece for minimum compression, a vented cast aluminum chassis for optimum strength and low compression.  It also has 3” copper voice coil for improved power handling, long-life silver lead wires, low damping rubber surround for improved dynamic linearity and a non-conducting fiberglass voice coil former for minimum damping.
