Mr. Paul C., I tried the capacitor on the 511s and they still didn't seem to want to go high enough.:scratch2: I'm thinking about adding these to the top of the 511s. I would build another birch veneered cabinet that would enclose both the HF horns, and sit atop the bass horn. I could then add whatever crossover components I would need inside that cabinet, with perhaps an L-Pad sticking out the back. These horns are supposed to start at 800Hz, but I don't think I would need to go anywhere near that low. If you think this might work, what high frequency drivers would you suggest for the Emilar horns. It's a standard 1 inch, two bolt deal. Thanks for any and all advice, Jay
Edit, my other option is to go with a pair of Heil ribbon tweeters that Urizen has so graciously donated to the cause (complete with rebuild kits). So, whatcha think?
