With various coverage angles available, these horns provide uniform on and off axis frequency response from Hz to beyond 16 kHz. In addition, the exceptionally consistent horizontal dispersion eliminates the midrange narrowing and high frequency beaming problems typically associated with conventional horn designs. The need for horn overlapping is minimized and lobing and comb filter effects are virtually eliminated. Computer-aided design techniques were used to derive the horn contours in the horizontal and vertical planes. Utilizing sidewall contours based on a polynomial power series formula, the horn design yields smooth response, low distortion, and even coverage.

The delay due to driver distance needs attention on this system. 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.
Try an Hz crossover for the Or, if you really like therun two of them with a degree angle between them. The matched up well with the Also thanks jbbl sharing your Xover points. For room coverage, I can fully understand why you like the baby-cheeks. I personally think that you would find that the a has too narrow a coverage. The frequency response was a little choppy. Hi Lutz, I have run all three flat front horns in all different sizes of room.
Let me give this some thought. I use A horn with h drivers in jbbl ht. The ideal match for the would a the A Bi-Radial horn. And maybe, that explains why nobody makes a larger version of the A. So, the a is going to have a horizontal dispersion that is ever narrower then 60 degrees, at your 6 KHz higher crossover point.
Hi Lutz What other components are you planning on using with the or horn? Baron, One more thought! I would strongly recommend going with a slightly higher crossover point of Hz with the a. After in taking into account your comments jjbl room coverage.
Thats why I changed to the baby-cheeks. Is it your setup in your avatar? Others, have brought up the a horn as a possibility. I feel the shorter throw horns sound better in a room. Based on the fact that the has a 90 degree horz. Zilch has already done a lot of the hard work involved in designing a system around this pair.

Tek Or, if you really like therun two of them with a degree angle between them. I forgot I have a pair of drivers mounted on BiRadial x horns. Something to consider is the dispersions characteristics of the other components. You are using 10, I have been at 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. Thats why I changed to the baby-cheeks.
