I had the same. The Janis is great for music and can't really be beat. However, for home theater, it is too weak. I ended up with a 15" 400 watt velodyne and don't miss the janis at all. Resale price on the Janis gear is the hardest pill to swallow.
Janis Woofer substitute
I have a Janis A-1 Crossover amp with out the original 12"subwoofer & cabinet what can be used as a suitable replacement?
