By this time most have had the original diaphragm replaced with a titanium type. If you can find a pair that have jlb diaphragms and don’t have shifted magnets, they’re great. The time now is Just my 2 cents worth of opinion Otherwise, cosmetically they’re pretty perfect for something this old. Hope 246 helps you. So I’m hoping that I can do something similar with the mids and highs and get better accuracy from the same components by building new cabinets that are better designed for the application.
Since I dont really need the long throw so much anymore, I’m hoping that putting them in sealed front loaded boxes will get rid of the honk up front. From a volunteer fireman’s perspective, outdoors is always the preferred method for burning cabinets. All times are GMT I do believe that the compression driver spec sheets from the s and ’80s were all derived from the horn. Hi Hey there Kevin and welcome to the LH forum. In aboutwe were approached by a club about installing a system in the bar, so we had them purchase these cabinets from the now closed roller rink.
You might want to give us some bjl info re your crossover situation, amps etcthere are folks here with way more knowledge than me that will chime in with the real down and dirty. My ‘s sound sweet with Jnl diaphragms. These are definitely near-field monitors.

I might even angle the bottom drivers into the room a little bit to improve the sound near the stage. I’d like to think I’m getting better performance from the horns with the diaphrams, but maybe not. Nice and easy to implement a single 12″ whether you use it in a horn or normal it will do the job for you and is W rated so its pretty bombproof.
Maybe come down lower with that changeover. Searching this forum, I saw there was a fairly big debate on the forum about 5 years ago on factory vs aftermarket diaphragms. I havent tweaked the crossover points in a long time, but my recollection is that 2.
It looks like these were a knockoff of the JBL L, with a different mid-horn lens: Looking into this some more, it appears that JBL made the switch from radials to bi-radials sometime in the 80s, presumably to reduce HF beaming. The is a very good horn for home use. Others will tell you more re the polar charactristics of that hornit will tend to beam somewhat at higher frequencies and some of the more modern horns will do a better job.
I just pulled these out of a pair of HOME stereo speakers my brother has carted around for years. At the time, the consensus seemed to be that factory sounded better, whether or not it was worth the 3x premium was subjective. View the Media Kit. That would make the system harder to move, but I try to avoid that as much as possible these days anyway. With drivers on them I always found myself giving them eq very similar to a CD horn in order for them to sound nice. For now, I’m going to keep the crossover at 2.
The potential for damaging your found money is high. Since then I’ve read a bit of anecdotal info about extending the range with newer diaphrams like the which is what I did – without realizing what I was doingbut nothing concrete on what HF can be achieved with hbl alnico magnets in the compared to using a or driver.
There are stepped diffusers over the horn.

The advantage I see to having two 10s for the mid packs is that when the room is full, the bottom jbo will be 24461 about shoulder level which should cover the dance floor area fairly well and the top driver will be just slightly overhead, for reaching to the back of the room.
The A’s that you have may be recones, I don’t remember them doping the cones that early but it is possible.
I have a pair that are mounted to horns in custom HF cabs. That way, I can front load my mids now which should make the whole system sound better before before making final decision on the horns. Sign up for a new account in our community.
If not you will need to think around that issue as these CD horns need a rising respose from the amp to play a flat response to the room.
I tried it on a K horn. I was planning to put the ‘s with the ‘s on top and get everything in a single mid-high cabinet, however I dont want to put a lot of effort into making my mids sound nice up front, only to find that the highs are not really cutting it. I’m not entirely sure that 2 x 10 is the way to go here.
IMHO the ‘s look better out of their cabs than in them, so I’m going to see if I can figure out a way to fly them naked without making them even more prone to ringing. By the way, the tips on the PS were very helpful They seem to be in tretty good shape and I think I will give them a try.
Now they have ‘s with Radian diaphragms, which handle a bit more power than the ‘s with their original diaphragm’s but sound very similar. Yes, they are worth something, actually quite a bit to the right folks. So I’m looking to improve the accuracy, without sacrificing too much SPL.
And maybe get a burn permit from the local FD.
