My favourite paper cone large woofer

This driver is perfect for deep bass in domestic high-end systems. It has the power to take active equalisation and deliver bass extension. It also has the T/S parameters to allow a modest sized sealed box to deliver really deep bass. The build quality is superb, like with all SB34NRX and SB29NRX drivers. The cast metal frame and wide rubber surround are great to allow high excursion without any distortion or power handling problem. I find this driver ideal for a lot of 3-way designs mated with a lot of different high quality mids. I'm using this with a Satori MR13.
