Geek squad helped me pick these out, but these thongs are awesome! Tested the first one out by playing Jurassic Park and DTS:X track over Shield Pro passthrough, and the room was shaking, was almost perfect reproduction of the bass and levels i like and enjoy, but then found out can even get better with the Denon receiver Geek Squad helped me select too and so bought another sub and the sound is absolutely perfect now, hookup easy with Audioquest cable. This one is the one, love going in my entertainment area now to enjoy old and new movies and shows now!

With 2 of these standing next to a pair of ML Aeons and a pair ofXT b100 it just doesn’t get much better. Now i just need some stands for the XT’s

I purchased the MartinLogan - Dynamo Foundation 12 when I purchased the MartinLogan - Motion XT F100 speakers. My system is for stereo only and in a sense I really didn't need the sub, the XT F100's go pretty low but they were on sale so, well you know! I have it set near it's minimum volume just to slightly enhance the F100's. If you were to use this in a multiple channel system 5.1 and up there's enough output to shake your rafters loose. MartinLogan speakers are amazing.
