Speaker break in?

Its easy to accept that speakers take some time to break in with all the mechanical parts that move and stretch and I have had new speakers that went from horrible to wonderful. It can take over a month.
More suprising is that electronics can change just as dramaticly. My latest amp was purchased new and sounded dreadful next to my other amp (that lists for the same money). It had rolled off highs and could not even track the basslines on some of my CDs. A few weeks of play and it is now at least as good as my other amp in all respects. Top end opened up and the bass is excellent now. Cant begin to tell you why, but there is no question that break-in takes place.

Totem recommends break-in at low to moderate levels. I guess if the surrounds were too stiff you might damage the bond between the surround and woofer frame. Take it easy at first, but it would probably take some real abuse to damage a woofer.

Some may say that break-in is a placebo effect but it is not. I am not one to believe every tweek that comes along is for real, especially high dollar cable hype. But I would not have kept my Totem Ones if they had sounded the same after break-in. I had other speakers to compare them to. The last amp I sold sounded so much better than my new amp that I would never had sold it if the new one had not changed so much. It may not have been so apparent if I had not had an other amp to compare it to, but it was quite obvious to me and my wife. And my wife can be painfully honest. My last four amps have all sounded different and if change was not for the better you can be asured she let me know!
