Howdy all.
I have wondered about the issues, if any, of using say an 802 and a 288 on the same multicell with a y throat.
Use the 288 for 500Hz to 2-3K and then the 802 above that. Lounge room listening levels.
Would it work well? Or just a bad idea?
probly a great idea
much math involved.
but that,s what computers are for .....
Immediately, phase issues come to mind as you will need an adapter to get the 802 onto any existing "y" which creates unequal length throats. Of course, one of the throats of the "y" could be shortened to compensate.
IMO, much of the 802's HF advantage would be lost in the length of the horn path.
HF energy dissipates quickly. A few feet out of the horn a gentle breeze can blow it away.
BMS tackled this problem in a way that other companies have followed, a coaxial driver.
Note that both elements are ring radiators.

Of course, something in a similar vein from the Harman folks:

Thanks bowtie.
Just needed to get some broader and more experienced thoughts on the idea. I had suspected it wasn't the best idea.
I'm with tomt, i think it's a great idea. The challenge is how to make it work and overcome the known, and to be encountered, caveats.Quote:

Great ideas are where innovation is born.
Once upon a time some fella got the notion that it'd be a good idea to run the HF transducer right smack through the center of the woofer. That went pretty well for Altec, eh? ;)
Look where Tom Danley has taken his company in little over a decade with his intense R & D on co-entrant(synergy) horns.
If it was easy, everybody would do it.
Hmm, taking a 'page' from TD's design, replacing the Altec adapter with a miniature waveguide [WG] long enough to get the 500 Hz 1/4 WL offset should in theory work well enough with a bit of DSP.
