break in tips

Uh, play music?

Play music, as Cruz123 says. Gently for the first 100 hours. Then with more dynamic, full range and complex music thereafter. Plan on 300-400 hours for a full range speaker with high quality drivers. If you play vinyl, don't expect that playing CDs on repeat will fully complete the process -- I always find that there's more to come once I start playing LPs.

I agree with Cruz123 and Rushton. I just recently broke in 2 pair of speakers (dynaudio c1's - first pair had a cabinet defect). I used a break in cd by granite audio which did not speed up the process. Sounded good right out of the box then at between 50 and 100 hrs they sounded absolutely horrible, but then it only got better until 400 hrs and now they sound GREAT. The break in cd did prolong the time frame in which they sounded horrible. Dynaudio recommends 300 hrs but I found 400 hrs to be the magic # of hours. I did play them 24/7 and all different levels. Some will say use recordings with a lot of bass to help break in the woofer. I have also read where some will face the speakers toward each other and wire them out of phase. That will lower the volume but make sure you listen to them forward facing to hear the loudest volume then NEVER exceed that level. Makes sense but read that after the second set were broken in.

Listen to Rushton's sage advise.I am in the process of breaking in new speakers.Its been 26 hours and a constant headache.300-400 hours cant come quick enough.

Xti is correct with the bass thing,i have found the ayre breakin disk trh 4 works awesome.Its the surrounds you need to get moving ask well as voice coil ect.
