What's the best small (ie, about +/- 12" cube) sub for under $1000? How about for under $1500? Sunfire and Pardigm Seismic seem well regarded but are a little pricey.
Onix Rocket UFW-10, $599.00 plus shipping and this little monster is very accurate and musical, also do well in HT down to about 25hz, acceptable base extension between 18 to 25hz but if you want higher output at these ultra low region then "small" sub ain't gonna happen, get a SVS PB2-plus and it will shake your entire house nicely.
