The delay due to driver distance needs attention on this system.
Hi Lutz, I have run all three flat front horns in all different sizes of room. Blaster, Thanks for the reply, I didn’t even think of a A. Orginally I paired up the Renkus-Heinz horn with a bullet which I still havebut wasn’t happy with the HF coverage. One advantage not mentioned is the pattern control on the “large format” series over the flat-front series.
If you look at the frontal Isobar contour charts, within the a horn’s spec sheets, you will find that the dispersion pattern narrows as it goes nbl in frequency.
Make sure that you run the all the way up and just bring the UHF in at 10k or 12k with a 6db rolloff just to fill in the top end.
Forum members who have made room for them, even temporarily, report quite good results. Baron, One more thought!

You are using 10, Hbl have been at Since, you are also suggesting on using a 12″ driver as a low-mid range driver. I have done this and it sounds pretty darn good.
And switching to Hz cleared things up nicely. And maybe, that explains why nobody makes a larger version of the A. Then I am not sure that any of the Flat-Front Bi-Radial Horns would be a good match as far as dispersion patterns are concerned.
Based on the fact that the has a 90 degree horz. Also thanks for sharing your Xover points. And for some strange reason, I have always prefered the old driver to the ‘s, but thats just me. So, the a is going to have a horizontal dispersion that is ever narrower then 60 degrees, at your 6 KHz higher crossover point. Honestly, for me the sounded so much better in the “sweet spot” but I stuck with the ‘s because I felt I got better HF coverage in room as a whole.
Let me give this some 2385s.

Others, have brought up the a horn as a possibility. Unfortunately, that “sweet spot” is pretty small. Try jbo Hz crossover for the I had A’s on the system initially and preferred the A’s. Should you consider a pair of the ‘s, I have a pair sitting in storage. Here is a picture of a pair of ‘s with the snout removed and mated to a pair of DDS horns that are very similar to the in pattern.
If you try to match the horizontal dispersion of each of the components, then frequency response will be smoother off axis as well as on axis.
You can tell the TRUE audiophiles by the size of their horns, eh? Or, if you really like therun two of them with a degree angle between them. Something to consider is the dispersions characteristics of the other components.
Hi Lutz What other components are you planning on using with the or horn? Fortunately, most of this change is in it’s vertical dispersion pattern.
But there are still some small changes in the horizontal dispersion as well. I use A horn with h drivers in my ht. I will post pic’s next week.
