Well I have read many issues with the MFW-15 and Emotiva line of amps. Worst of all, they have restricted the forum to read only. Damage control? That is not a good customer service by any stretch. As much as I would like to try out the MFW-15, I don't think I will get near it until they address the amp and other issues with it.As much as I like and trust SVS (I have a PC-Ultra), there is nothing really bad about AV123. They have been around since 2000 and have a very respectable line of "Rocket" speakers.
The MFW-15 is a beast (big & heavy) and a good buy for $700. A very good subwoofer designer, Mark Seaton, was involved in the creation of the MFW-15.
