Ever since I discovered the exploding ball at the beginning of the Star War DVDs,
I've been using it to test the ability of whichever sub/subs that I may bring into my system. Sort of a make it or break it test.
Most subs, I've had, can't handle this "test" when the SPL meter starts approaching 100db. They either shut down or their driver/s start making some ugly noises. I take the measurements from my listening position about 12' from the sub.
My current subs, a pair of Revel B-15's, are the only subs I've had in my system that reproduce this exploding ball well into the 100s, 116+ is the highest I've dared to push the exploding ball, without a hint of breaking down or shutting down or worst, the drivers bottoming out. At that point I usually chicken out and lower the volume in fear of damaging the subs or the foundation of our house, as the entire room is shaking and rumbling.
Has anybody else here used the exploding ball as a measure of their subs performance?
