Last night it was tuned very high and I had a wallet on there to temper that not-quite-good CS, but I've got it tuned sort of medium low and wide open with an Ambassador X and Yamaha DC hoops at home right now. Super fat and incredibly sensitive all the way around, and I've yet to find a range that makes it sound bad. Quite possibly the fattest 5x14 I've ever played.
Yeah, those thick metal shells are sooo sensitive. I really think a thick metal shell, tuned somewhat low, 4-5” deep, is just an incredible sound for so many gigs.
