Should you consider a pair of the ‘s, I have a pair sitting in storage. I will post pic’s next week. Hi Lutz I can fully understand what you mean by the ‘s “sweet spot”. 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.

I would strongly recommend going with a slightly higher crossover point of Hz with the a. Let me give this some thought. Our others points are almost exactly the same. If you remove the snouts on your ‘s, you can bolt them onto 1. Is jbll your setup in your avatar? You can tell the TRUE audiophiles by the size of their horns, eh? And switching to Hz cleared things up nicely.

After in taking into account your comments about room coverage.

Baron, One more thought! 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. The frequency response was a little choppy. JBL does or did make large biradial horns of that type–the series. The ideal match for the would be the A Bi-Radial horn.

Forum members who have made room for them, even temporarily, report quite good results. Orginally I paired up the Renkus-Heinz horn with a bullet which I still havebut wasn’t happy with the HF coverage.

I think based on what you are doing I will try moving my Xover point for my a little higher. 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. Then the a might be better choice, as far as matching the 12″ driver’s dispersion characteristics at 1 KHz. Thats why I changed to the baby-cheeks. But there are still some small changes in the horizontal dispersion as well. Your right, it does match the ‘s. Lutz, I had a similar setup that ended up as per side 2- 15″ h’s 1- 12″ H 1- 2″ H on a A H tweeter I don’t think it was a ideal system but it had a lot of range.

The A and the both have the same x degree coverage. Also thanks for sharing your Xover points. On the point of coverage, the a would do a better job.

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. 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.

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. I personally think that you would find that the a has too narrow a coverage. Blaster, Thanks for the reply, I didn’t even think of a A. I feel the shorter throw horns sound better in a room. Others, have brought up the a horn as a possibility.

I agree that the is far too “long throw” for your room. I had A’s on the system initially and preferred the A’s. Try an Hz crossover for the
