SVS PB-3000 stopping and starting midway through REW measure

[konga056]

Im having a weird issue with a pair of PB-3000 that I can't seem to figure out what's going on. When I'm doing a measure using REW it'll stop for after a second in the beginning and then continue. I'm not sure what's causing this. This is happening regardless of the starting frequency range I use. I have a pair and its happening on both. However this doesn't happen on my other subwoofers.

Below is a view to kinda show what's going on.

It might be some kind of limiter kicking in? Seems almost like a limiter with a slightly delayed attack.

Where's your volume at when you do the sweeps?

*Edit: Boy, yeah that driver is really moving! You might just have it up too loud?

REW does start sweeps at the low end first. Like Shady said it seems like you're hitting a limiter of some kind.

Is there an easy way to tell its hitting a limiter? Right now I have the AVR set at 0db subwoofer trim and the sub is set at -25db.

If it stops doing that at lower volume levels, than it is the limiter.
