subwoofer canton ergo good for music??

I can have this sub for a good price but i cant listen it before have it. Its only for MUSIC listening on a very large room. Does it sound musical, punchy, tight. Or maybe its sound more like ground vibration. Opinion please....
Iown Canto speakers for my video setup. Canton is a good manufacturer. They make a high quality musical product. The 'Canton' sound is fast, great clarity, tight. never sloppy at all.
