Great speaker, I already had two Motion SLM XL and fell in love with them, I was looking for a center channel speaker and after buying other two I finally choose the SLM, the high frequency drive has no competitor unless you pay a lot more, folded motion, the best relation quality price ever. Super slim design, no tower on the floor, easy set up, modern look, incredibly loud at 94 dB, you won't believe this sound pressure level is coming of this flat on wall speaker (you has te option of using the stand),. You are going to need a subwoofer to went below 110 Hz but if you are buying this beauty, you can pay $150 for a Polk Audio subwoofer at least, and upgrade your sub later if you want more bass. I'm not buying a speaker with a high frecuency drive if it is not a folded motion one, forget the manufacturer advertising, listen to the speaker if you can before buying it, compare and then choose the one you like. For the price it is hard to find a beter slim/flat speaker, it is not cheap, but compared to where the prices can clime, I'll buy Martin Logan forever.
