I have a non-Atmos pair of the BS22 and they're pretty good $79 speakers.
If I did have the Atmos "A" pair, It would only take a few minutes to connect the sections together for stereo out of curiosity. It would either sound better or worse. I'm 100% certain it wouldn't sound the same!
And again, that's only if my amplifier would cooperate with the 3Ω nominal (or lower) load.
