"Ah, look what I found, DIY speakers that might have the potential to actually sound good. hmmm, I will build some...." many days and nights later... I decided to re-use my kappa pros and build some omnitops. At first I tried the CD horn tweeter route and even then it sounded better than the junk boxes. I could really hear the midrange, much cleaner, and using the same drivers from the old boxes, sounded so much better. Not much louder, but better, cleaner. I played a few shows with those (remember I play noise music, so it's at full volume nearly all the time). I found that the high end with the CD horn and crossover filter was just too much high end and I was still blowing the tweeters. I finally got around to building some piezo arrays, just strait ones for the moment with 8 in a line. My first test, I thought something was wrong, they were so much quieter and lower in volume that the CD tweeters. But when I turned it up, then I understood. With the lower volume of the piezos compared to the CDs, more midrange comes through and it sounds much more even in relation with midrange to high end. Now I can hear things in the midrange I wanted to hear before when the tweeters were too loud. I can turn up the high end effects and still have definition in the midrange effects at the same time. Makes for a much easier performance when you can hear everything. I can't wait to get some melded arrays and compare again.
First reality test will be in a few weeks. Then I can turn it up loud and see what kind of limits I can push with these piezos in place.
Up next are 4x 16" T39s to replace the Risson.
PS - I hate those chevron corners. They cut my arm up when I move them around, the edges just stick out too much and I can't get them flush to the cab. So I use the metal corners now, a bit more expensive but they sit flush and are more durable I think. Just avoid all plastic parts entirely, those plastic top hats don't work either. They flex a lot and wobble. Now I know....
