I'm looking to purchase a subwoofer to augment my Sonus faber Domus Grand piano speekers. My room is about 8'h x 14 x 18 or 2000 cubic feet. My listening is pretty much exclussive to music, and my tastes range from jazz to rock to orchestral to - some - folk. I would prefer a smallish unit. My budget can range up to about $2000. I'm auditioning the REL305, and have followed their setup, and while the bass is okay, I hear a lot of distortion at higher volumes. Any suggestions for a better sub for music?
