It was set to 0 instead of -10. Because of this, I had turned up my sub to compensate, beyond what I used to have it at.



0 is actually louder than -10.

If it's built like my 600, I really don't believe you've damaged it in any way. It's designed to throttle back no matter what you throw at it. But even throttled back, when pushed to ridiculous SPLs, it will distort, it will chuff, the grill and the top of the cabinet will resonate.

What I've found most objectionable from my 600 was resonance from the cabinet top and the grill when pushed to ridiculous SPLs. 95% of the time I don't push the 600 because the SPL is too high for me and other listeners. So I put a folded towel on the top and then my beaver on top of that for those crazy moments. And if I'm gonna watch a movie with tons of special effects at ridiculous SPLs, I take the grill off. Problem solved. The port noise and distortion is only noticeable when I play a 22hz or less test tone. And I'm usually not in the mood for test tones very often .

I am constantly amazed at how well this sub peforms with both movies and music. It's incredibly smooth and transparent. I feel Axiom has balanced SPL and product limits very well. Most listeners wouldn't even pick up on these potential areas of improvement at the extreme operating limits of the product. I often wonder though how this sub would sound if it contained more polyfill. I've been meaning to try that but have never gotten around to it. If anyone at Axiom has experimented with this and can describe the effects to me, it may end up saving me a lot of time.

So maybe you need to buy yourself a nice beaver like mine.
