Heres what I have setup for my sub. I have an AA avalanche 15. I have it in a 10cuft box with a ~16hz tune. The port is a 6in diameter PVC pipe with a length of 2ft. I am powering the sub with a ep2500. The signal is coming from a denon 2809ci.
Now I currently have the ep2500 with the dial set at the 9o'clock position with the denon sub level down to -4. I know this does not mean much in regards to voltage settings. But I am having this nasty snap sound coming from the sub.
For example I was playing the last couple scenes in transformers where there is alot of stuff blowing up and whatnot. A couple of the scenes dig real deep. The bass is impressive but when it gets REAL deep, my sub makes this gut wretching SNAP sound. Not a bottoming out sound, but like you are snapping some thin wood. At which point I turn it all the way back down, and the sub operates normally.
I come from the 12volt world so I have had plenty of experience with subs, even blew my own once, so i know what bottoming out soudns like, but I have NEVER heard this sound before. On scenes with normal bass, I can turn the dial past 12 o'clock and at that point it will be substantial bass. But the only way I can safely eliminate that snapping sound is to turn the dial allll the way down. The dip switches are all set correctly except for the clip limiter(off), which I would assume would have no effect as it only limits the clipping on the amp side (correct me if im wrong).
I duplicated the sonotube designs from either this site or htguide, with exception i used a box instead of a sonotube, I have not heard of anyone having this problem before. Does anyone have any advice, the only thing I can think of is making a new box and bringing the tune up to 20hz.
