Less than 1 year old Velodyne CHT-15 sub. 750 watts peaks, 300 watts RMS, Freq. response 23-120hz. Great sub...I am only getting rid of it because I have moved to a condo and need something smaller. Other wise I would definitely keep it. You can check out Sound and Vision Magazine and see how it faired against a lot of other subs. The CHT-15 was ranked as the most bang for the buck.
