Overview
Add big sound to your saddlebags with Velocity 10 inch subwoofer. The Velocity RZ10 subwoofer works by reinforcing and complimenting the other speakers on the bike. This results in a much more impressive and forceful sound. Designed specifically for performance in saddlebags, the RZ10 woofer has the correct balance and suspension to thrive in a saddlebag as an enclosure. The RZ10 is also designed to work well with lid speakers.

Installation notes
The RZ10 subwoofer is designed to perform in conjunction with other smaller speakers on the bike (6x9s and 6.5") to make those speakers sound much bigger and bolder. The RZ10 subwoofer is not designed to be used as a standalone subwoofer like one that you would find in a car audio system. These woofers must be high passed (not low passed) at 45hz with a 24db per octave slope. The final usable range is 45 - 400hz. Bikes with a factory radio must be flashed with the TecnoResearch tool and the Rockford Fosgate flash. No equalization of any kind should be used below 200hz. If used with lid speakers, the lid speakers must have suspension and motor characteristics that will allow it to share the enclosure space with the subwoofer. Not all lid speakers are capable of this. We recommend the Velocity R690 which is the speaker that all of our OverDrive and soft dome 6x9 component kits are based on.
