Most of today’s car audio products consist of several custom tooled parts, all which cost extra money. The design goal for RF-8W was to engineer a phenomenal audiophile-grade subwoofer that did not cost a fortune. If you’re looking for chrome or something really flashy, look somewhere else. If you’re all about performance, look no further.

We used simple, classic materials for the best sound quality; non-pressed pulp paper cones, foam surrounds, and Conex suspension.

RF-8W is also a great fit in a factory 8” subwoofer location...
