RE: The review was absurd

It's interesting that on a forum that eschews subjective evaluation he uses (for speakers) subjective evaluation to confirm what he's not measuring. :)

Anyways, I don't think the measurement results are so much about dipole short-circuiting, but rather lack of boundary reinforcement. Even a typical box speaker measured well above the floor would measure differently when sitting on the floor. This is a simple 2pi/4pi environment effect that would manifest with all speakers.
However, typical box speakers are usually designed for above floor usage, whereas the Magnepan speakers are designed to sit on the floor. This is the essential "issue" with the PIR noted. The NFS claims to encompass that discontinuity as result of the measuring scheme......but I'm not convinced it's effective for all types of speakers. After Amir has tested another half dozen (or so) floor-standing dipole speakers then maybe the issues will become clearer.

Now, nobody is going to accuse the MMG/LRS of having room-filling bottom two octaves bass. They are NOT legitimate full range speakers and do need a sub-woofer to be considered such in a typical domestic situation. But, to characterize them as having "no bass below 300Hz" is not correct.
