Default What would you do with Six B&G Neo3-PDR tweeters in array?

My latest ebay purchase is six Neo3 tweeter array in curved steel frame, with passive crossover designed around 1.5khz 24dB/octave, obviously from a custom speaker project.

I did not realize they were so curved when I bought them, but I assume they should still be used standing vertically. DC resistance measures at 5.2 Ohms.
I am brainstorming ideas to integrate these Neo3 arrays with my dual 8" bass units, which currently sound awesome crossed over to Radian 475PB compression drivers at 1kHz/18dB via Bryston active crossover. The horn setup actually sounds fantastic, but this was an impulse buy. For now, I'm trying to play with alternative presentation, but I may consider just adding the Neo3 as (super)tweeters if that doesn't work out.

When I thought they were straight, I was going to just mount them on some wood panels and stand them up on top of my woofer modules, but since they are so curved, I may need to devise some sort of steel tubing contraption with help of a machine shop. Any good ideas would be greatly helpful

OK. I found out where these arrays came from. Makes more sense.

Maybe I'll make something similar with smaller woofers and put them on my wall. Or I could straighten out the curve some more and experiment in my 2-channel system.

After some sweat and toil, the system sounds Fantastic :thumb:
Driving the Neo planars directly via Bryston active crossover, my Elekit 300B amp can play to ear-deafening levels.

You are one lucky fellow who is going to have great sound. I've long thought that tweeter power requirement is not met. Some big brief peaks in music like women's choirs and if you unmask those peaks, sounds great. Before going ESL, I used a 9 tweeter array of fried egg drivers.

Instead of invoking line-source theories, just mount them as I am sure intended: as a horizontal array to fill your room in a natural way.
