My recommendation is to cover the armrests with 4xMA's then 8xIso's at all other points. If that doesn't do it for you then cover the remaining 2 points at the rear. The new Isolators are so compliant that they decouple at a far greater rate than any feet I've ever used. The top and bottom caps are what keep these rigid. Without them they're gushy. It makes for a much more efficient platform.
Yes, I went from 2 to 4. Originally I thought about using 8xMA's. My thinking here now is that would turn this into a Z axis dominate array, as opposed to an Y/Z axes dominate setup. I've set mine up with Minidsp channel 2 to 2 middle MA's and channel 4 to 2 outside MA's for testing purposes mainly. I'll never run just 2 even if it's only me watching.
With my setup, there is no hotspots as every part of every chair is energized equally. There's no hint of dynamic compression. I never thought you could get to much TR from 5-12hz. Now I'm not so sure. I've backed off my gain from 6-7db and these are still so jarring its distracting. Now I don't experience that ever so slight upper midbass that is the reason why most owners [email protected]
I used a 80hz but now it's no longer needed. The benefit is better midbass presence. My 8x18's can crush it in my small room and really pressurize but these can completely dominate them. From this point forward its balancing the LCR/Subs/MAs that I'll focus on. As I said, I'll try the 4 per seat, just to know, but I don't think it'll change my mind.
