Yes - I suppose I described a long and tall ESL63
![]() Now, I don't know if I'm hit with spherical sound waves at concert hall 8th row? I'm sure one could have quite interesting time experimenting with such a system anyway... ![]() //

That's the one firing in rings, right? Basically Tom made the equivalent of that in a horn shape.
While I do use a straight array, the DSP will try to make it into the right shape again. Most people say of arrays: they make everything sound huge! Well, not if you absorb early reflections, avoid diffraction and use DSP to make them behave. They sound huge on full scale recordings, small if the recording captured that. And anything in between. If I weren't using arrays, I'd have horns. But I'd need to have the room for them too, which is why I have arrays. Good choice? I'm not complaining!

I would be interested to see what you could come up with relaxing the wiring restrictions, if the vertical could be widened somewhat that would open up a lot more tweeter possibilities. If I was to do anything to my arrays I would most likely rebuild the whole thing as a v2 so exploring these sort of possibilities is interesting.

If you look at the bend sims I posted, even that would be a possibility to widen the output, up to a limit. Also Crumboo's wiring scheme is a different example on how to have more ways to widen the beam.
I can't promise to try it, as I am fully committed to see my own filtered array come to life. I've spend a lot of time coming up with that, it would take me at least an equal amount of time to try another schematic. You'd have to know the listening axis height in advance, if using a tweeter, can we do the tricks Crumboo showed, to have the design axis below the central tweeter axis? What does it do to the IR? What do the different heights look like in such a case?

I'd figure it would look something like this:
(tweeter position is missing, the zero position has no driver) Schematic: As the correction I used the FIR correction file for a single TC9. According to line array theory, this should give me a 3 dB/octave drop, right? Positions 0, +100, -100 and +700 (floor and ceiling reflections on at -12 dB)

I'd say it may have a future
![]() It looks pretty even in response up to 4 KHz... All it really needs is a killer tweeter (and most probably adjusting the height to make it fit).

Beautiful result!!
![]() Y position for D20 and D23 is 0, I guess it shouldn't be? Anyway - really nice! I'll copy your schematics and try it for myself ![]() |

Interesting distractions can be worthwhile
![]() That looks like much easier directivity to match at about 4K, when I've tackled the latest distraction I'll see if I can find a match ![]() |
