Hey all, been a while since I dropped in about my 9844A. I have those up and running with some replacement Altec networks and they sound sooo nice.
Anyway, the next project for me is to take the Klipsch top hat off my Klipschorns and try some real deal stuff on top.
I have a line on some JBL 2360 and Altec 511B. I don't yet know what drivers might come with them, but I think the JBL has diaphragm-less 2441 (been a while since I saw them). No idea what would be on the Altecs. Aesthetics are not an issue, as they are in the process of being moved to the 21' x 16' studio in the basement.
I'd like to try to get this done as a 2-way if possible, but I'm not offended by a tweeter on top, either. I've done some reading today about JBL drivers for the 2360. I like the 2485 in that it is usable down to 200Hz, but it only goes up to 6KHz so the tweeter crossover point would be critical. The other 2" units I saw all had 500Hz as their listed lower limit, but some stated that they could be used lower with reduced power ratings. I can't imagine I'd be giving the mids more than 20W at home, so it's not scaring me to cross these at 400 as the Khorn is now.
Initial evaluations will be done with an Ashly XR2001 4-ch 2 way/ Stereo 3-way active network. 24dB/oct with a nice response adjustment that alters the response surrounding the crossover freq. I'm considering working up passive networks down the road.
These JBL drivers don't seem to be readily available & are quite expensive. I've also read snippets that the discontinued EV DH1A would work well. I have access to slight deals on Radian as well if they have a good choice.
Any suggestions or comments? I'm looking at trying the 511B as well, but I'm more enthusiatic about the big old Bi-Radial at the moment.
