Old timer help? jbl 4507 4645, altec lansing 3156 2226 2380 2445 3110A/ 3115AB argh!
Yeah, I'm new here, 1st post, yada yada, cut me a wee bit of slack. So long story short, I finally got lucky on CL, and after a 13+ hour round trip arrived back home with a pair of jbl 4507's and a pair of 4645's. When I had time to dig into what I actually had, the magnet assembly was totally gone from one of the 18" 4645 drivers, and the other 18" is apparently a generic non jbl driver. Bummer.
On to the 4507's. 2445J's mounted to 2380's on top, sounds fine. I figured these probably had 2225s in them, but seller told me they had Altecs in them, turned out to be a good sounding pair of 3156's. Further inspection found a 3110A crossover in one and a 3115A in the other.
Battery of questions, if you don't mind.
1. find 2242H drivers for the 4645 cabs? (dbx 234 a decent electronic crossover for this application? x-overed at 80-100hz or so?)
2. I had planned to put a pair of jbl 2226h's in these, but to be honest the altec lansing 3156's sound pretty DAMN good, thoughts on which are better?
3. When I saw the the crossovers installed, I figured they were 3115A's or maybe 3110A's, turns out I got one of each. Its my understanding that the 500hz is the preferable crossover point, or does that depend on my keeping the altec 3156 or switching to the jbl 2226h? I ain't rich, should I sell both on fleabay and beg here for a schematic for this configuration for a fixed 700hz crossover?
4. any improvement going to 2446js over 2445's?
5. any other input or advice appreciated.
thanks much,

I'm still diggin it.
The only Changes I have made so far:
1. I picked up another 3110A, so now I have a pair of the same thing. If anyone has a 3115A they wanna part with, let me know, I might wanna hear what a pair of those sound like.
2. I picked up a single 2446J with a 2385A I have been listening to, attached to the channel that is closest to my seated position. More detailed, more highs, maybe a little bit too "harsh"? Need more time to compare I think.
3. I picked up a pair of EV DH1A's 8 ohms, coupled to hp94's. Way too strident, think some/most of the problem is the horn, didn't give these more than a few minutes of play time.
4. Right now I am listening to JBL 2447J's with 2332 horns, and I think for home use, these might be the best choice.
5. Picked up a pair of 511B horns, just because they were close by and priced right. Think I'll try them out on some other speakers I have in another room. Been wanting to replace those EV 8HD horns anyway, wonder what the 511B's will sound like with EV 1824M's?
Hey, if nothing else I am having fun tinkering with it all. :bouncy:
