This is the document with measurements:
http://support.bryston.com/downloads/Loudspeakers/Bryston_Speaker_Technical_T10_Manual.pdfIt’s a work in progress with placeholders and various spelling mistakes, so model-specific graphs are coming if they continue their documentation tradition. It’s surprisingly free of audio BS, though it seems like a stretch to call a speaker stack a line array. I’m glad bipolar subwoofers are coming back, and hope Axiom gets them too.
I assume only the active models will have such tight tolerances. The NRCC research says that if your loudspeaker has a listening window and sound power/directivity index curve that is straight and predictable (free from spikes, dips, and changes in direction), it will win double blind listening tests. We seem to like neutral speakers with no resonances or colorations (and I consider the wrong bass level to be a coloration).
Bryston should be able to please neurotic/disagreeable spreadsheet jockeys/armchair quarterbacks that hang on every word that EAC and ASR say, while at the same time also pleasing the connoisseurs/enthusiasts/gatekeepers who buy audio by the pound and decor sense by the carat.
For the rest of us, it doesn’t matter. The marginal utility gained from trading in an Axiom V.4 loudspeaker will probably be minimal and would be better served with multiple subwoofers or finding trustworthy music curators.
