Default ESL panel length

If one were to build new Acoustat-style panels for one of the full height models (1+1, 2+2, Model 6, etc.), instead of building two panels to reach the full height, could you make (assuming the cube louvers could even be sourced) 8' panels and make a single panel for each speaker in - for example - a 1+1? Would there a real difference, performance-wise, between two 4'x9" stacked vs one 8'x9" panel?

In my estimation no absolutly zero difference other than it would be much more of a fuss to make. I have to build a set of 0ne plus 0ne size panels some time soon and I am considering horizontal sections rather than vertical ones simply to ease construction. Smaller sections will require a smaller jig to build them on. Diaphragm stretching will also be less of a fuss for the same reason. YMMV but that`s my take on it. Best regards Moray James.

I have been wondering that myself,and think I have the same conclusion as you.

Hi,

That's the way I'm making my ESL's for years. Horizontal is simple and works well.

Cheers,

Thanks for the input, fellas. It was more of a hypothetical, but was just curious. I do think if it were done this way there wouldn't be the gap between panels, which can affect response when the ears are at that same level. But even if 8' louvers could be had, the build would be more difficult.

hella: tell me can you really notice the gap between your current Acoustat panels? For one its above your ears at seated position and below your ears when standing. You can do exactly the same trick with horizontal panels. I always found that when I was at the optimum distance from my 0ne plus 0ne`s (which was about 12 - 14 feet) the panel sounded seemless anyway. Perhaps closer you might notice if you had your ear at the exact position between the two panels but when is that going to happen? Just my thoughts YMMV as always. Best regards Moray James.

I do find a little discontinuity at the panel juncture, a bit of a change in the HF response if I use a taller chair that puts my ears closer to the transition point. I do sit a little closer to the speakers than your setup, due to room size, so that probably makes it a little more noticeable. Not a big deal at all, and only under certain circumstances, but always looking for ways to get closer to perfection.

Hella: there is no good reason not to build up a full length set of panels if that is what you want. You can solvent weld two sections of panels to achieve the lenght that you want. The Quad 63 is a good example of stacked horizontal sections and I have never heard of one complaint along these lines but if full lengtht works for you go for it, you will gain a little panel area so nothing wrong with that.
Hey allen if I am not mistaken Hella has bumped his high voltage supply already, Hella please correct me if I am mistaken. Allen great to hear from you buddy how`s it hangn in the key state? What`s in the system right now? What`s waiting to hit the floor next? Best regards Moray James.

Thanks, Moray. Yeah, more being curious than actually looking to go in that direction. You're right, I did bump the voltage on my interfaces, but I've gone to Acoustat Servo amps since then, and prefer them. The interface mods were definitely worth doing, however, and I still have them in case of Servo problems.
