I really don't have enough history with LowBeats to know where they are coming from!
They typically do measurements, but in the case of the A45 BS, they only present a chart for "IM spectrum at 94dB", but no simple FR chart. This chart seems to show that the A45 BS is SPL/distortion limited!
I have not yet tried out their Oracle system for presenting the sound of the speakers they review to us, but it is an intriguing system that makes some sense.
A magazine like The Absolute Sound will make a statement like "these are special speakers and must, therefore, be paired with a special amp" just because the author thinks it reads well!
Ha! I did find an impedance chart for the A45 BS in their discussion of the Anniversary series family. They point out that the A45 BS has the lowest impedance at 4 Ohms due to the single woofer:
Here is link to article (again frustrated that they do not get more specific with measurements of the various models). I do wish that was my LR!
