BDS is not that big a problem if spkrs are positioned to get maximum and smooth room gain.

The room gain should and does IME fill-in the floor reflection cancellations to some extent. Compensating for it with an extra driver adds complexity and reduces clarity, BDS compensation throws away dynamics as well as eating 3-6db of power, and detail and nuance as well.

I've lived with a pair of speakers with no low-pass (no BDS compensation) for a long time. Their actual diffraction behaviour is as smooth as possible, just like Olson predicted for a sphere. The enclosures are very quiet to boot.

So that's two causes of distortion at any level effectively eliminated.

I bought the speakers instead of QUAD 57s which I was set on, before I heard these.

There is no complete answer to anything in audio, nor is perfection possible, it's all interdependent even orthogonal.
