I'm the guy who owns a BOSE Accoustimass 16 II sub and reading this forum makes me realize I'm a little fish in a BIIIG sea. II'd like to upgrade but need some help. I've been reading great things about the SVS subs but I'm open to suggestions. I've got a budget in the $500-600ish range. I've read ported vrs sealed and still not sure. So hopefully you all can help me out?
Here is what we've got to work with:
Room Dimensions: 17ft long x 12ft wide x 8ft high
Def Tech Mythos 10 Center
Def Tech Mythos 3 (L/R)
Mirage Omni Sat (Sur L/R)
Bose Accoustimas 16 II Sub
Onkyo's TX-NR626 Receiver
PS3 Blu-Ray
My set up:
