the frequency response is pretty much the frequency response of any small horn. it wouldn't really need anything other than a protective cap. then the "ambience" horns could be run with the mains on perhaps a second main channel.
i could see them being set in a receiver to come on with music and be left off for movies.
when linkwitz added the rear tweets to his orions, he really went crazy with how much they added to the experience and linkwitz is a pretty reserved guy. he gets the credit for the idea. i was just thinking about applying the principal to horns.
My HF horns only go down to about 3-5Khz IIRC (They are old Gauss 1502's and I have not measured them so I could be wrong) and the mid horn only covers 250-6000hz.
Also the idea of mounting a horn over the LP is just too messy, even for me
. But then again if it was just an ity-bitty small horn...
What I was envisioning was just adding a rear facing HF horn directly behind the forward facing one. This is still possible if split the HF signal, add a delay of 10ms and then amplify separately. I have everything I need except a digital delay. But even if I had the delay I'm still missing about 3 octaves...
Having said that I have a CD and horn that'll cover 500-12Khz, but they are very large. I could 'fly' them above the main horns, but they hold their directivity down to 500hz, so they might be to 'tight' to give enough ambiance. Not to mention the WAF.
I'll most likely be ordering a dcx in the up coming months for a subwoofer project. I could temporally implement it as a delay for this idea if you think one of my collection of horns and drivers would work.
I've also got a B&C DE10/ME10 which might be well suited to this task, but I'll have to check the specs to see how low it goes.
BTW I assume they make some kind of XLR 'Y' splitter, I'd need one of those too.
FWIW I just posted up some pics over a LHF, so you can see what I'm working with.http://www.audioheritage.org/vbullet...l=1#post297297
