Hi J.B,
We try to get the two speakers within about 1/4 dB of each other, because even though our hearing cannot detect that small a difference in loudness (1 dB is considered the detectable threshold of loudness differences) tests have shown that if there is a bit less than 1 dB loudness difference, although we can't "hear" it, the itsy-bitsy louder speaker will be perceived as "better" in the blind tests.
Axiom's new listening room, still in construction, will contain a speaker shuffler to exchange speaker positions to randomize the role (that's ROLE) that room placement variations introduce to speaker testing.
Regards,
Alan
