SB Acoustics SB29NRX75-8 10" "Norex" Natural Paper Cone Woofer -290mm- 8 ohm

Low Q for vented box (see below). 11mm xmax!

This 10" woofer features a proprietary composition paper cone with a special coating. The rubber surround has been carefully chosen to properly dampen the cone movement. The open-structure cast frame has been specially engineered for minimum reflections and good air flow. This woofer will perform best in a ported enclosure (see alignments below).
