Hello,
I have two TAD 1603, one of them is used and one is freshly reconed.
The used one looks perfectly centered but is significantly softer than the reconed one. I have therefor put a 20hz sine-wave for about 5 hours on the reconed woofer to break it in. I guess I ran it with about 10watts as it made about +-5 cone-excursion...
Actually I donīt feel a change in the suspension, it is still significantly harder than the used one.
So how long do you recommend to put a 20hz sine-wave on the woofer to break in?
