Here's the setup... Room size, 8x14... Axiom M22's up front, Axiom Merak center, Yamaha HTR 5460 A/V receiver, Bose 301 rears (to be replaced, obviously.) 60% music, 40% home theater. Currently using 2 KLH 10" subs, O.K., but would like something more "musical"---good for jazz w/acoustic Bass, for instance. Private house, so I can usually crank it up when I feel like it. Should I get the 25-31, or for $50. more, the 20-39 with the above setup? Would one "blend" better with the M22's, or be slightly more suited for my tastes in music? Any input appreciated. Thanks, Gary.
