Recessed tweeter mount uses standard 1-3/4" hole saw
DDC™ (Discreet Dual Clamp) Tweeter Mounting provides concentric clamping pressure around the perimeter of the mounting hole. This results in maximum ease of installation.
Used these to replace the factory JBL tweeters on a 2008 Tacoma and it's a very nice improvement in sound and frequency. Definitely balances the sound of the upgraded speakers and sub. It can get a little loud and "hissy" on certain words at high volume but some EQ adjustment can clear it up and leave it sounding very nice. Good deal for the money. Very good mounting design to clamp it onto a bracket but very concerned that I had to bend the wire terminals for it to fit into it's support bracket. I felt like it would break any second. Would have preferred this already be designed with the terminals in the proper orientation.
The price was unbeatable from all the other sources, I received it when you said I would, and it was boxed/packaged to insure that I would receive a unit that wouldn't have been damaged in shipping. Thanks and I'm looking forward to doing business with you again.
