In each case you are running a deal higher than the optimal band for each driver in a hi fi sense I would be looking at or less for your 15’s and bring your HF down to or even Look to a separate driver, or find BE phragms or even Jbl compression you want to squeeze more than 10k out. This is tweeter territory. I may see if I can find a pair of 2nd hand clones or maybe borrow a pair of loaded s. It is the case that some of that old gear can be made to sound very very good indeed.

So I’m looking to improve the accuracy, without sacrificing too much SPL. I’m fairly sure that replacing the diaphrams with ‘s compresson the HF response, because the system has never lacked for high end.

Hadnt thought about making the s into beer cans, but now that you mention it, if I dont end up using the s and no one wants to buy em, these things will be worth a tidy sum at the scrap yard. I would expect that the diaphram would make most of the difference in HF response, but dont know for sure.


compressoin 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. The is a very good horn for home use. This amount is subject to change until you make payment.

They have been in service as the high frequency drivers crossed at 2. As far as your HF driver is concernedsince you have installed a dia in there you effectively have a and it should ocmpression cleanly as high as you will need to go.

There is a ton of info in the forum and on the web about this driver. When I rebuild my mid cabs, the ‘s will be further up overhead so wont compressiln your head off up close.

One of the reasons that I want to stick with 10s for the mids, is that the ones I’ve seen that are made to be midrange drivers tend to be reasonably flat until K or so.

I do believe that the compression driver spec sheets from the s and ’80s were all derived from the horn. That spec sheet is partly what got me concerned in the first place, because the HF response on the seems to roll off a lot faster than the They were originally installed on horns with throat adapters over 4 cabinets loaded with ‘s.
