The Stereo Review's Stereo Buyers Guide 1983 edition has the following description of the ADC L1530 speaker:
Acoustic suspension 3-way floor standing professional monitor speaker system with 2 10" high-compliance Stifflite woofers in separate chambers, 2" soft-dome midrange, 1" samarium-cobalt soft-dome tweeter. Features single switch biamplifier conversion, tweeter level switch, tweeter, midrange protection fuses; mirror symmetrical midrange/hifrequency baffles for minimum diffraction; walnut veneer finish with radius-edged solid walnut corner inserts, removable black cloth grille. Frequency response 25-20,000 Hz +\- 3dB crossovers 500 and 4k Hz; sensitivity 95 dB SPL/W/m; power rating 150 W nominal, 300 W peak program, impedajnce 6 ohms; 50/5/8" H X 23-11/4"W X 12-1/8"D..........$1250
This model was not listed in the 1984 Directory being superceded by the L1090 and L1290 and I do not have the issues prior to 1983, so I do not know when that series came out initially.
I do have a pair of these in my garage and I had just hooked them up after purchase to check them out. They did have one defective midrange and I replaced it with a similar one that came from an L810. I find they are good speakers for their time, truly full range with dynamic impact, but very dry. What is your comment on these speakers?
