Tube Traps and other room treatments

Sounds like the "Panel Traps" are the same thing, only a tad bigger, without the diffusor, and for the same price. I use the diffusor side away from the speakers for sidewalls, and toward the listening position on the wall behind the speakers (except with the Maggies in the smaller room, of course).

Frescoes are the best and most versatile product any acoustic treatment company ever came out with! (They've been on the market about a year and a half. Go to tubetrap.com to learn more about them. Also, they're aesthetically beautiful...and easy as hell to move around. They're about the bass absorbing equivalent of a 10 inch full round. You don't use them in the corners, but along the walls, so they don't need to absorb low bass. TO SUMINSBY: Full rounds actually aren't as goosd as Frescoes to go along the walls; full rounds work best in the corners, and really 16 inches are the minimum ones that work well for the bass range. The 20 and 24 inch ones are ideal if you need to smooth your room's bottom octave energy. I've only needed to smooth the middle and upper bass energy.

I use 16 inch full rounds in the corners behind each speaker, and use Frescoes on the walls behind and beside the speakers for first reflection points. I also use two 18 inch X 6 foot Echobusters, and various RPG Profoam. You already know this R Suminsby, but for the rest of you, THE FIRST REFLECTION POINTS CHANGE relative to how many speakers there are. For surround sound, there are many more complex reflection points, and it can be tough to decide which ones have more effect, and which ones have less effect. I don't have a reference surround system, but if you've read ALL the literature, you know more than me already. The advantage with ASC's freestanding traps is that they can be moved around, which is perhaps what you are already doing when you go from 2 channel, to multichannel. In any case, I hope everyone else is use these essential devices.
