wheelz999 - I'm in a similar situation as you as I don't feel that I'm quite getting the performance/response out of my 500 as I expect. My problem was that the 500's original amp had a faulty volume control and I couldn't calibrate the sub to match the same level as the other speakers. I didn't realize this to be a problem for some time, though, as I just recently had the opportunity to use an SPL meter (thanks to jakewash) to calibrate. Before that, I simply ran the 500 extremely hot and didn't realize (due to my ignorance) that my sub was playing too loudly. Now that it is properly calibrated, I don't feel it's response is "quite right". Keep in mind - I probably don't know what "right" is and that may be the problem
I'm going to keep working on it. And, much to appreciation, I'm going to lean on the expertise of jakewash to keep helping me out when I have the time.
Good luck with your tweaking.
Bryan
