Woofer break burn in time?

[promitheus]

I just finished my new speakers and the bass is too low. I know they need time to break in, but my question is how long?
I have in my system 4 woofers HDS 205 from Peerless.
I just wanted to hear other DIYers opinion before I start to make changes on the Crossover.

It depends on how you're exercising them. If you want to hurry the process along, set up a sine wave at a low frequency (like 30 Hz) to move the cones at maybe 50-60% of xmax. Feed the signal to both left and right speakers with the polarity reversed on one of them. Face them toward one another, with a small distance (like 15-20 cm) between them. That should cancel out most of the noise. Let this run overnight. At that point, let the speakers cool down and recheck the resonant frequency; it should be lower than it was at the start. You've now got some broken-in woofers.

...or you can just let them rock for a few weeks before you do any serious tweaking.

I gathered that he was in a hurry

I am not really in a hurry. I was just disapointed they sounded so floppy. Almost no bass in the beginning.
I knew that would happen but you know how it is.
After so many weeks of making the boxes they sound crappy.
Just wanted to know what others have expirienced.
