Over the last 6 months I am sure I have "enjoyed" my sub a little bit more than I should have. This has got me wondering if anything is wrong with it.
Currently it sounds as far as I can tell the same. However, I am one of those people that doesn't believe his own senses.

Besides SPL and THD compared to a known correct one is there anything else to look for?
It is a sealed horn so moving the driver to listen for scrapping is a bit of work.

Thanks.

BTW: It is a Lilmike Cinema F-20 with a Dayton Audio RSS390HF-4 15" powered by a Bash 300, so even at full power I doubt I caused any real harm.

You'll know when it is not acting right. When one of my tempests I had loaded into the f-20 started rattling I knew immediately. Due to the nature of a horn, the noise was amplified greatly.
