*****UPDATE: The driver has now been sold, only the amp is now for sale! This is a great amp that can be paired with Rythmik's 12 or 15 inch drivers. This amp is used in both the F12 and their F15 subwoofer.*****
More info on the amp:
More info on the subwoofer driver:
This is some of the best gear you can get if you are building your own sub. All that's needed is the box, and Rythmik Audio provides many guides to assist with creating one. The 15 inch Rythmik Audio driver is also used with this amplifier.
If you are interested in one or both of the items, contact me and make an offer.
