To all M&K fan, you made the right choice. M&K makes excellent speakers that's why Lucasfilm sound system uses them and other big name companies. Just go to their website and check it out. They are not popular with the consumer is maybe because of their pricing. My first M&K speaker system are the S-85's and my subwoofer is an M&K MX-125. I still have this system by the way. Recently I upgraded to the pro series and I have the MPS-2510P for my main speakers. I have 2 MPS-5310 subwoofers. You can feel and hear the bass on these subs. It will deliver clean low frequencies and at the same time shake the room. I dont go to theaters anymore because I think I have a better system than they do. For those of you that are undecided, if you have a chance of auditioning M&k, do it before purchasing a new sub. They're not cheap but you will be happy with them.
