A Woofer Built to Perform in a Harley Saddlebag, Using the Bag as an Enclosure

The RZ10 ten-inch mid-woofer is designed to play well with other speakers in the same bag without sacrificing bass response. 

Sold as a single unit (not in pairs)

The RZ10 is not designed anything like other 10" woofers. This mid-woofer has a number of design characteristics that allow it to perform in a saddlebag at high volumes where a car audio-type subwoofer would fall on its face. The RZ10 has a lower voice coil inductance which allows it to play a much wider frequency range than a traditional subwoofer can. By allowing the woofer to play up high into the same range as the lid and fairing speakers, the woofer is able to acoustically reinforce what those smaller speakers are doing at the lower end of their own range. This makes for a much more aggressive punch on the bottom end when all of the speakers on the bike are sharing a bunch of bandwidth. The result is something that you just can't get with a subwoofer that is limited to 100hz and below (like a car audio subwoofer). This mid-woofer plays from 45hz to 400hz and does not require a low pass crossover (high pass crossover is required). A low pass crossover is not required because the speaker naturally rolls off above 400hz on it's own without any need for equalization or a low pass crossover.
