Sure! As for searching anymore? No, no time for that yet. I used cheap $20 tweeter line arrays that I ripped out the tweeters and these speakers dropped right in. The boxes are attached with typical metal electrical pipe (conduit) clamps. Tightened with some rubber inserted between the pipe & the clamp so it will hold, but I can spread them apart with a bit of effort.

Note the Peavey speaker is upside down (lol, it's what I had and it turned the pipe mount to the top.)

Now that I know it will work fine, I'll make some much smaller (depth-wise) boxes to further reduce the weight. I'll also space those 3" speakers closer together to more accurately grab the effect of a true linear array. Go search for Bose L1 photos and you should find a cross-section that shows how they vary their 2.25" speakers in the column. They're pointing in several directions in the L1. As I shrink the box, I'll also add one more to gain a total of 12 speakers in the array.

Keep in mind that they don't push nearly as much air as the 15" would, it doesn't take a lot of cu. ft. in the box or column cavity. (Note todays surround systems and the L1 cylinder itself.)

I do have some more experimenting to do for the sub-side, too. That's a full-range 15" speaker there. It may be of value as-is. I'll play and then sub a true subwoofer. Overall, it breaks down into three manageable pieces: pole/woofers, mixer/amp box and the sub.

If anyone wants some specific views....back, etc., let me know and I'll take more pics. What I do know now...it will serve well for a crowd of 300-400 and play overtop a drummer that uses Sonars and bangs hard.
