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. And for the a Horn 285a are several options, the “Slot” or the new with the right PT wave guide would be best. 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. Blaster, Thanks for the reply, I didn’t even think of a A. 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 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. Is it your setup in your avatar?

For room coverage, I can fully understand why you like the baby-cheeks. Since, you are also suggesting on using a 12″ driver as 2385aa low-mid range driver. I have used nearly all 2″ horns jbl has made in various projects and while the will give you the wide dispersion, the X series of 1.

Our others points are almost exactly the same. I use A horn with h drivers in my ht.

I personally think that you would find that the a has too narrow a coverage. Forum members who have made room for them, even temporarily, report quite good results. Try an Hz crossover for the You can tell the TRUE audiophiles by the size of their horns, eh? The is nice but the is even better. 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 higher in frequency.

If you remove the snouts on your ‘s, you can bolt 2385aa onto 1.

The matched up well with the Orginally I paired up the Renkus-Heinz horn with a bullet which I still havebut wasn’t happy with the HF coverage. This does make a difference when there aren’t any reflective walls and the crossover point is low. Unfortunately, that “sweet spot” is pretty small. But still, when you are listening in that spot, boy it’s so sweet JBL does or did make large biradial horns of that type–the series.

And maybe, that explains why nobody makes a larger version of the A. I have done this and it sounds pretty darn good. Hi Lutz What other components are you planning on using with the or horn? Hi Lutz, I have run all three flat front horns in all different sizes of room. Then the a might be better choice, as far as matching the 12″ driver’s dispersion characteristics at 1 KHz.

I think based on what you are doing I will try moving my Xover point for my a little higher.

Hi Lutz I can fully understand what you mean by the ‘s “sweet spot”. Hbl will post pic’s next week. So, the a is going to have a horizontal dispersion that is ever narrower then 60 degrees, at your 6 KHz higher crossover point.

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. Based on the fact that the has a 90 degree horz.

One advantage not mentioned is jl pattern control on the “large format” series over the flat-front series. Your right, it does match the ‘s. But there are still some small changes in the horizontal dispersion as well. On the point of coverage, the a would do a better job.

And for some strange reason, I have always prefered the old driver to the ‘s, but thats just me.
