Info Needed on ADS L1530s


Greetings Audiogoners:
I recently purchased a used pair of L1530s and would like to rebuild the crossovers and rewire them. The existing crossovers will not allow straight bi-wiring (full bandwith going to high and low frequency inputs). The back panel of the speakers specifically warn against sending frequencies below 400Hz to the high input. Does anyone know what, if any modification, I can make during the rebuild that will allow straight bi-wiring? I appreciate any assistance with this. Thank you. klccharter

leave them as-is. Anything you do is only going to make things worse most likely, and ruin any long-term value they would have. They are not very common. They were set up for bi-Amping (with external crossover) which has far more merit as an idea, than any type of biwiring (which is essentially useless with these).

Fooling around with the Xover if you dont' know what you are doing is more likely to result in blown tweets and mids than anything else. Given that these dome mids and tweets are unique to the L1530 and L2030, and are no longer made and rarely avaialable used, blowing them would result in a useless pair of rare speakers.

Interestingly, I saw someone recently selling off some ADS stuff from NYC area. I think in that, they had a C2000 system. They definitely had a pair of PA1s, which are the factory biamp modules that screw into the back of the L1290/1590 and I think 1230/1530 systems. Quite rare, worth having.

FWIW, I've owned L1290's, M15s, CM7s but currently just the L300s (all a/d/s/), plus 2 pairs of Aerials (the speaker company run by Mike Kelly, who was the brains behind a/d/s/ when the L series were being produced).

The top of the **30 line is the legendary L2030, big, rare, not that pretty, but apparently excellent sounding and quite efficient (uncommon for a/d/s/)

Yes, if not using the C2000 or PA1 setup (or another factory ADS setup) you'd need some other sort of line level crossover (Bryston 10B, etc). Frankly I'd suspect the C2000 would beat up on anything from Sonic Frontiers, esp. given that it is designed to work with that specific speaker. They are great speakers, and unless you use the factory a/d/s biamp/crossover stuff, I'd just run them as you are now. Enjoy,
