I have a Hsu STF-2 subwoofer that I purchased about 2 years ago. I bought it for a room that measures 14 x 13.5 x 8 and its use is 100% for movies.
I recently purchased a Denon 2112 and when I went to go do my setup I found that my subwoofer wasnt working. The company believes I need to replace the amplifier - which they can send me for ~$190,
I dont know whether my room REALLY needs anything bigger or more powerful. So while part of me thinks its worth spending ~$500-600 to upgrade to something better and bigger, part of me wonders whether just spending the money to repair it may be sufficient for me.
