Hello all. I want to take a moment to say thank you for this forum. If I have learned anything, it’s that there is a great deal I don’t know about the subject.
In recent years my JBL’s have been part of a 5.1 system with little emphasis on music. The system was used by the whole family and after the third Ortofon cartridge was broken I elected to remove the turntable and pretty much left it as a home entertainment setup. The room was such that the placement was far from optimum for a good soundstage anyway. Then the big CRT died and the whole thing pretty much fell into disuse. Things change. With the death of the Mitsubishi and the kids out of the house I see nothing but opportunity.
I recently sent my D130A's to be reconed intending to use my JBL's as mains for a new front projection theater system. The use of a retractable screen would allow me to relocate my mains to a more favorable position at either side of the fireplace. While I am anxiously awaiting their return, I’m spending quite a few hours searching posts primarily about this 001 system, which I've had since new. After much reading my focus has shifted somewhat, from theater to hi-fi, and I'm considering other repairs or modifications to improve my sound.
I have been looking for info on my crossovers, figuring that they could use some attention after 40+ years. This system is in a pair of ‘66-‘67 vintage C35 enclosures which I would prefer to leave in tact. As far as I know the crossovers are working, though I have not played them in some time, but I doubt they're in spec. Looking inside the crossover, it looks like a mess to replace the caps unless there is a way to melt that pitch like material surrounding the caps and inductors. I assume the fix would be to clip wires and somehow fit the new caps in the remaining space. Anyhow, I seek advice, as I am looking at either replacing the N1200's with a new crossover and saving the stock ones, or maybe an active crossover could be the ticket. I think I’m getting a bug, because the idea of shopping for a new amp(s) sounds like a great idea.
This may be a subject for another thread but I've also seen a couple of posts regarding some of the sonic deficiencies of the 001 system. Some have suggested adding a mid bass to assist in the 600-1200Hz band. If I go with the active crossover is there a proper driver I might use between the 130A and the LE175DLH? I would prefer this mod to be in a separate enclosure. Could a pair of Minuets do the job? I see a pair on CL asking $600 (ouch!!). Also along these lines, do my 63 year old ears stand to benefit from a UHF crossed over to the LE 175 horn? I consider my hearing to be OK. Earlier I considered adding an 075 but decided against it because they had a reputation of being shrill sounding. I can build an enclosure if I must, but the tech stuff I leave to others, so the closer to plug and play, the better for me.
My current (HT) setup is powered by my (old by HT standards) Yamaha DSPA1- pre out to a Mac 2125 and LF out to a M&K mk10 sub. I also have a Mac C29 which will probably go back into the rotation when I dig out the Thorens and the LP’s.
Feel free to tell me I’m barking up the wrong tree if this is the case.
Thanks in advance.
