ADC Soundshaper 3025 (ca. 1990)

Little is documented about the ADC Soundshaper 3025 three-piece speaker system. Here is what the record shows. It was introduced as a new product in early 1990 and paired two full-range satellite speakers with a separate subwoofer. The subwoofer cabinet measured 11 inches high, 7½ inches wide, and 17 inches deep, and weighed 15½ pounds. A molded black plastic cap housed the port that radiated the acoustic output. HiFI-Stereo (May 1990, p.50) measured the system's overall in-room response as ±5 dB from 55 to 20,000 Hz, which incorporated a shelved high-frequency characteristic from the room curve. The magazine also noted that the satellites alone sounded quite well balanced, though they produced no significant bass below their own range.

Beyond that single test report and the February 1990 new-product announcement, no production years, original price, or further specifications have surfaced. The 3025 appears to have been a brief entry in ADC's early‑90s loudspeaker lineup, positioned as a compact sub/sat system for home audio.
