I haven't had the opportunity to listen to any SVS subs yet, but I was curious to hear how they stack up to M&K subs. I currently own and love the Miller & Kriesel MX-100. It has a tremendous output, unfortunetely I don't have a way to test the SPL's, but I am pleased with it and it continues to surprise me. Are there any SVS subs that are comparible to the MX-100. Just to help the design is push-pull with two 12" inch woofers, one forward facing and one upward facing from the bottom into the cabinet. The replacement fuse size is 4 amps, 120 volt, so I assume the amp is quite powerfull. If anyone has any insite on this your expertise on the subject would be greatly appreciated, Thank you.
