I recently tore apart the TLs I made for Eminence Beta 12 LTRs and moved a pair of Aristrocats into the living room and put a pair of JBL D-123s in them using Heil AMT-1s with a 6db high pass placed on top over the VCs of the JBLs. (5K, D-123s running free)
For those not familier with the Aristrocats, they were designed by Paul Klipsch in the 50s (mono days) and are basically a cross between a TL and a horn and made to use a corner for bass extention.
I don't have them in a corner but do have them kind of corner loaded with them sitting close to the wall and the sides of the tall isobaric subs, but facing straight ahead.
Extremly efficient, I am not sure of the D-123s, but I believe they are a tad higher than the 97 db of the Heils, but don't really know.
I did not try the Eminence in the cabinets but compared to them in the TLs the 1st thing that is real noticable is the much more prominent bass response that does not need lots of SPL. 2nd is the magic of the Heil crossed at 5K instead of 10K.
The sound is extremely natural and very fast. My good friend Russ Gates bought me a copy of the superb live recording "Jazz At The Pawnshop" and it is really like being in a small club with the musicians there. This CD is great, I imagine the vinyl in mint is even better.
After lots of years of looking I believe I have found something that borders on being great. If you ever see a pair of these "Crats", don't pass them by, take them home and put some great drivers in them and enjoy.
In the future I will reline the insides and try a bit of fiber to see how that works out, but don't think there will be any great amounts of improvement.
I really don't get on the puter much anymore, so if I don't reply to questions, please don't be upset. I will try and check back, but my internet connection is touch and go.
Hey Wayne! See you in Tulsa!
