    Interesting. From what I hear most subs tend to "pop" for a while when driven hard until broken in. Then they no longer do it.

    I buy pre broken-in speakers :lol:

    However, when I replaced my blown SL1000 tweeters with Peerless replicas, I found that for the first week or so, they seemed to crackle and give off static at loud levels. Now they're fine.... a result of break-in?

    I bought a pair of Rockford Fosgate Punch 8" woofers to replace the woofers in my MAs, and they come with a little note that suggests that you refrain from playing the woofers at loud levels for the first 20 or so hours of playback time, in order to give the speakers a chance to break in.... are they just blowing smoke? Who is to say.... I never play 'em that loud anyway...

    Maybe you didn't give them enough time to pop? I've heard that car subs need to break in before supplying too much juice.

    Polk recommends this also on their Momo subs.

    Henry - I would avoid any FR sweeps that exceed 80 dB. It is very easy to fry a VC on a sweep, especially when the SPL level exceeds 100 dB for extended periods of time.

    Also, I just recently read that careful cross torquing of the wood screws is extremely important to prevent warping the driver basket and misaligning the VC in the gap. Do them all a little at a time and torque them all very evenly.

    Remember not to drink until you are DONE swapping the drivers Henry.

    I agree with that for a stamped/steel basket. And I still did it for a cast basket, primarily to ensure that the flange sealed evenly and completely all the way around. But uneven tightness shouldn't create a problem with a cast basket. That stability is sort of the point. Hold a good solid cast basket in your hands, and it is apparent that having applied uneven torque to the bolts would NOT stress/distort the basket. Perhaps the head of the bolt would break off or you'd have an uneven seal around the driver... but it ain't gonna bend.
