Thanks Colin, I haven't seen that design; is it german? Here's a rough render of the sub/coffee table. Wd probably need to isolate the top from the main cabinet. I'd put the 2.1 plate amp on the underside with the woofer so then have to move the controls off the amp and mount them somewhere. Also want to add an iPod dock with dac

Sorry to "rain on your parade" but you're going to meet some difficulties trying to mate up that omni directional speaker to any sort of subwoofer located in a coffee table that's Xed over at 150Hz, particularly with a 2.1 plate amp - neat little design tho.

Thanks for the compliment. Yes thats an issue with the Dayton, a fixed high pass of 150 hz(2nd order). I would have thought that the actual x/o point is lower( where the 2 slopes meet) and can be adjusted down to 120hz or more?
The Keiga 2.1 has adjustable hi/lo pass.

XAMP-M1 and M2 used in combination will be more flexible and give you variable crossover points

I believe some AV receivers have adjustable roll off for the subwoofer outputs.
