Info Needed on ADS L1530s

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.

Ed sawyer gives great advice! I own a pair of these, and a a pair of 1590's, which are similar. Biamp them if you want a big improvement, but don't mess with the crossover. ADS made a C-2000 Biamp System Control specifically for the 1230/1530/2030. And these speakers are darned good used full range, as is.

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/)
