I have 2 high end JBL studio 12's, and 2 AR unlimited capacity tweeters that i would sell if anyone is interested. They were backups that i never needed from a system i had years ago. The 12's are the ceramic cones that you can hit with a hammer. ( so they claim, never tried it ) I don't remember the wattage or ohms on them, but if anyone is interested, i could dig em out and see. They ain't cheap though. The 12's i would want $150 each, and the tweeters $100 each. Would probably do $450 for all. The speakers that they were backup for used to knock my rearview mirror off the windshied, and blew my back window out of the frame once. The tweeters came out of the sound system for the Loyd Noble Arena in Norman Oklahoma, and can handle anything you can push at them. They were never installed there, just ordered extra for that system by a friend that was installing thier system. I believe i paid $225 each for them at wholesale. They have 40oz magnets on them i believe. The speakers are about 4 1/2 inches, and the magnets are 4 1/4 lol. They are the cleanest tweeter i have ever seen, but very heavy and hard to mount because the magnets are so big.
