PRO 003 Woofer
(to price list)

The PRO 003 is a 6" woofer with a slightly shorter voice coil than my other woofers. It is still much longer than most typical woofers, of course. In a system using a true subwoofer, this would the ideal choice for your mid-bass driver since it will go as low as you want, relieving the main woofer of any work outside its ideal range.

It is shown with a butyl rubber surround in these photos:
