Is it your setup in your avatar? But, assuming for a moment, that you really got your heart set on a 2″ throat Flat-Front Bi-Radial Horn, then swapping out the for something else might be a better choice. I have done this and it sounds pretty darn good. Unfortunately, that “sweet spot” is pretty small. Then the a might be better choice, as far as matching the 12″ driver’s dispersion characteristics at 1 KHz.
Try an Hz crossover for the But there are still some small changes in the horizontal dispersion as well.
Something to consider is the dispersions characteristics of the other components. Can you post some pictures on it? Our others points are almost exactly the same.
The frequency response was a little choppy. For room coverage, I can fully understand why you like the baby-cheeks. I agree that the is far too “long throw” for your room.
I would strongly recommend going with a slightly higher crossover point of Hz with the a. I feel the shorter throw horns sound better in a room. Or, if you really like therun two of them with a degree angle between them.
Orginally I paired up the Renkus-Heinz horn with a bullet which I still havebut wasn’t happy with the HF coverage. After in taking into account your comments about room coverage. 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.
Also thanks for sharing your Xover points.
I think based on what you are doing I will try moving my Xover point for my a ubl higher. The is nice but the is even better. The delay due to driver distance needs attention on this system. Your right, it does match the ‘s. Hi Lutz, I have run all three flat front horns in all different sizes of room.
You can tell the TRUE audiophiles by the size of their horns, eh? This does make a difference when there aren’t any reflective walls and the crossover point is low.

I will post pic’s next week. And maybe, that explains why nobody makes a larger version of the A. If you remove the snouts on your ‘s, you can bolt them onto 1. Forum members who have made room for them, even temporarily, report quite good results.
On the point of coverage, the a would do a better job. Thats why I changed to the baby-cheeks. And for the a Horn there are several options, the “Slot” or the new with the right PT wave guide would be best.
I personally think that you would find that the a has too narrow a coverage.
