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

There has been over the last 6 months a few ads for Spatial Audio "Turbo" Series speakers, especially the Turbo M-4 S which retails for $1999.00

Is the "Baffle less" design provide the same wide and deep stage as the Magneplanar model .7 or 1.7i  or other similar planar design, and offer accuracy and musicality? .

I have seen only one or two reviews of their speakers in the audio press.

Thank you,

S.J..

@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.

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)
