Features
Mounting: The tweeters offer multiple mounting options; choose flush mount, surface mount, or angled surface mount. The tweeters are shipped in the flush mount housings and the angled surface mount housings are included. The back of the flush mount housing and the top of the angled surface mount housing combine to create the (non-angled) surface mount housing. Once installed in any of the housings, the tweeter will pivot slightly to optimize imaging.

The tweeter output level can be changed from flat to -3 dB by moving a jumper pin inside each crossover.
