Tom,
Like you more projects than humanly possible to tackle.
My thought and experience with the 7.2 it’s more about current than watts. In every scenario I had high current amps I preferred them over high wattage.
Your amps will have a firm grip on The 7.2. The bottom end with the right amp is infectious.
I’ve come up with a design for 7.2 bases that will not raise the height of the speaker but provide a sonic improvement from my experience. I’ll share it with you by sending you CAD/model files.
In listening room I am filling the wall the speaker are behind with lambs wool. I’ll tack a silk black backing over it. I’ll take cabinet grade baltic birch void free plywood and throw it on the router and cut an array of various sized holes and slots throughout the entire sheet. I’ll install and the look will be holes and slots recessed back and highlighted with the black silk material which will absorb the excess energy coming off that wall.
In the corners I will roll lambs wool in 12" diameter roll the length of floor-to ceiling height. I will frame it out and set wool in. I will cut the birch plywood the same as I did the other but these will be curved so it will look pie shaped. They will be built in bass traps.
Natural cedar T&G ceiling with some diffusers is the plan. Western cedar does an amazing job on its on of getting rid of slap echo.
I did a mock up of a very sophicated suspension rack based on a Indy Car front suspension system. The final material will be 25mm Panzerholz for the base.
I always aimed for the fences but some days the mind is willing but the body is weak.
