Spatial Audio M4 Turbo S. Is its design competitive with other baffleless speakers?

My buddy has a pair of KC IIs in a small apartment and they sound great They're barely 42" tall from the bottom of their bases, without iso devices, which I highly recommend. Having owned Magnepan 3.5Rs and Accoustat 2 + 2s , the KCIIs are a super bargain

Clayton designed Emerald Physics and then started Spacial Audio. 
I was oh so close to buying the Spacial's, but they're too large for my room.

As I read further into the review, I agree with the additional complexity of DSP: the KC11s are passive, and do not require \ biamping (but you can if you desire).

FYI, I find speakers, especially baffless ones, sound best with zero toe in

Haven't heard of them.

Their concentric driver looks identical to the one used in my Emerald Physics KC IIs (AA/USAudiomart), which I am selling only because I am moving up in their line to 3.0s. Mine have a WireWorld XO upgrade ($4500)

@lowrider57 Yes, that’s me.Thanks for the shout out to my blog, and @sunnyjim,  I hope the information there is useful to you. The blog has both my original review of the M4 and my subsequent review of the M3 after trading up. I love both of them and think they are great. I will also say that with the right amplification – I am moving out toward solid-state, myself – the image beautifully and throw a gargantuan, immersive soundstage, if you’re into that sort of thing (which I am)!Hope this helps.

Steve eventually traded-up to the M3.
