I have seen the Dynabox and just have not pulled the trigger. I will give it a try. From what I saw, it looked like a good thing to have for inwalls. I appreciate hearing from someone who has had them.
MBM - I like it. Had it in the family room at one point and it was awesome. Now in this smaller room, I am going to have to keep adjusting it to get it dialed in right. Right now it is boomy with the power down a good bit. I have it and the sub hooked up to SMS-1 and I may be trying to hard with all that. Interesting about the stuffing. I may give that a try.
