My subwoofer is killing insects, is this normal???

I made a higher tuned subwoofer using a 10" old JL car sub a few years ago in my garage. Basically I was going to see just how loud it could get before something bad happened. I saw 3 spiders come out from their hiding place, curl up and die. Seriously. One dropped down from the rafters and didn't make it to the floor before it was dead.....still hanging from his web. Thought it was strange. I'm sure there was even more because it was mu garage, but I didn't look.

I don't think it's unusual though.

Spiders do not like my tapped horns. They just get done building a web in them, and then I come along and watch a 5 star bass movie.

Gotta make an example of the first ones so the next one won't settle in.

While I have plenty of spiders in and around the house, no particular carnage noted near the main sub (which is sealed but haven't checked the ported subs lately) Have found dead bugs near my main sub, but they're more likely the victims of spiders. Now if they'd kill or keep at bay the rodents...I've tried and doesn't seem to even bother 'em. I've got a squirrel scratching on the roof right now and major bass isn't even fazing him. Found this with a quick google, so maybe it's sensory overload http://blogs.discovermagazine.com/80beats/2011/12/15/study-each-hair-on-a-spiders-body-is-an-ear/
