Well, it’s clever. And I suppose if your listening room in anechoic, and your budget for speakers matches Crutch’s price range, and your ear shape matches the microphone baffle, it might help narrow down which speakers to order for a home audition. To Crutchfield’s credit, the only real way to buy speakers, which is with a home audition, is possible because of their return policy.
I bought my first serious pair of speakers after exhaustive trips to audition various speakers in dealer showrooms. I was never really happy with my choice. I bought my current (and probably final) pair of speakers after a three month in-home audition, and I couldn’t be happier.
