BlackPearl#1 that is what I used to secure my AT28 tweeters in my grills.

 

I went a little different route. I borrowed ideas from some other folks here such as baseman and CovertOlds and used BT30s and mounted them behind Boom! Stage I grills.

First, I removed the stock grills and separated the cloth covering from the plastic backing.

Second, I flipped each one over so the curve is towards the back so the tweeters wouldn't hit the grills. As a result you have to swap left and right sides to get the holes to line up.

Third, I cut the center out just enough for the tweeter to fit through.

Fourth, I inserted the tweeters into the holes using a thin spacer so the tweeter doesn't stick too far back when to nut is screwed on. I was worried about clearance to the woofers in the BT brackets.

Lastly a piece of treated grill cloth between the grill and the tweeters before installing in the fairing.

 

Looks pretty slick.

 

I still need to take some pics with them installled. I forgot to mention that I used 1/2" spacers between the DD AW6.5s and the BT brackets like CovertOlds did so I would have enough room between the back of the tweeters and the woofers.

 

Looks very nice and clean. I think I will go the same route. Thanks for posting the pics and step by step install. Now I need to start rounding everything. Once again thanks

 

Thanks. I know the AT28s are a better tweeter but I thought they would be too tall to mount behind the grills. I also plan to check them again after a few miles of run time to make sure there are no cracks in the plastic from the vibrations or contact between the woofer cones and the tweeters.
