Burning in period Nautilus 800?

B&W Drivers should need only a few minutes or maximum of a few hours. If it still sounds different after a week then your old drivers may have been damaged/over driven or something is wrong (for example did you make sure that the seal is airtight around the new drivers that you installed?).

I'd stay away from suspect products that claim extremely extensive break-in periods, as this is indicative of poor design, poor choice of unstable materials or poor manufacturing tolerances. The parts that most flex in a good driver (surround and spider) are specifically designed to have as minimal effect as possible on the sound you hear.

By your own estimates, you appear to have spent between two and five years breaking in speaker woofers (assuming that you always have one pair of the 40 to 50 speakers being broken-in continuously, 24/7)

Since you have found that crossover capacitors take three or more times longer than woofers to break in, I began wondering how often you actually get to hear the equipment AFTER break-in?

Wow....that's dedication! Or are you pulling our legs?
