What tangramca said…
I have a problematic asymmetrical room, and try as I might, I couldn’t get sufficiently satisfying bass without then overloading the room at high volume.
I now use Spatial Audio M3 Turbo S speakers, and the problem is gone. Truth be told, I do like a little more bass than they provide, so a pair of Hsu ULS-15 subs complete the picture. The sub settings are different; the closed side of the room gets less gain and the Q is set to minimum.
If I had a perfect room or something close to it, I’d probably revert to box speakers, but for now, the Spatials do exactly what I need them to do.
I believe it’s a case of ‘horses for courses’ with open baffles.
BTW, I’ve heard Bache’s (OP) speakers, and they sound great.
