I just recently purchased a new sub; the entry level Rhthmik, and have read a number of comments concerning a subwoofer break-in period. When I purchased my 64" Samsung plasma TV 2 years ago, I took the time to use break-in slides for the first 25-50 hours of useage. However, I've not read anything concerning a new subwoofer break-in period or procedure. Any advice would be appreciated.

+1...........and expect it to loosen up after about 15 to 20 hours of use.

I would think that it's more like 15 to 20 minutes.

If you want it to work as well as possible right off the bat running a 20Hz sine wave at 10-12 volts for 12 hours will do it, but if you just want to use it about 40 hours of normal usage will get it there anyway.

I find that a good two weeks of listening will loosen it up enough. I typically listen about 3 hours a night, so for 14 days that comes out to around 40 or so hours.

+2. Moderate levels for the first few hours - in my experience, less than ten - and you should be good to go.

This thread sort of reminds me of some of the threads I used to see in the past.. vented versus sealed. Many don’t believe in break-in at all but then many do. I have seen manufactures even get into it stating the need or not the need. I remember one actually doing it for the costumer themselves. As for me, I just calibrate and then check the calibration a week or so latter.

The good news, after a couple of months of normal usage, it's all good.

This.

However I would modify that statement with the word moderate instead of normal, as normal is a subjective term.

So is "moderate." tongue.gif

It's okay to use subjective terms such as "normal" as we all know that "normal" usage does not include blasting the system from the gate.

Personally just normal use of the sub is the easiest, but then so is watching a variety of content on a plasma....YMMV

So, to clarify, we are talking voltage across the driver, not in to the line level sub amp.

Have you thought about maybe storing in it’s placement for a month or so? It would then acclimate itself to it’s new surroundings before you start breaking it in. smile.gif

And if you want to make sure it will perform at altitude you could get it a hypobaric chamber for the break in period, too wink.gif

Yes, which of course would be a PITA to measure with a powered sub. But that's the only way to know you have enough excursion to do the job without damaging the driver. Ideally all drivers would be broken in at the factory, but break-in takes time, and time is money.
