Dynacord ADS (from 1976)
The Dynacord ADS is a compact two-way bass-reflex loudspeaker from the mid-1970s, built for professional stage and PA use. Dynacord was described as Europe's largest manufacturer of electronic music equipment in Mix Magazine (June 1988, p.95). Dynacord's own 1975 catalog places it in a professional loudspeaker lineup described for "Stage" and "P.A." (public address) applications, and hifi-wiki gives a construction start year of 1976. It's a straightforward, workmanlike PA cabinet from a company better known today for its amplifiers and effects — and documentation on it is thin.
What the record shows is a capable small PA speaker. The ADS is rated at 60 W DIN (100 W for public address, 120 W music power), with a frequency response of 70 Hz to 20 kHz and a crossover at 2500 Hz. Sensitivity is 92 dB/W/m with a dispersion angle of 90° × 60°, and nominal impedance is 8 ohms. Both hifi-wiki and the Dynacord brochure agree on these core figures. The cabinet is bass-reflex, described by Dynacord as a "bass-reflex compact system" — consistent with its intended portable PA role.
There are minor discrepancies between sources on physical specs: hifi-wiki lists dimensions of 700 × 420 × 280 mm and 15 kg, while the Dynacord brochure gives 660 × 420 × 300 mm and 13 kg. I'd trust the manufacturer's own literature on this one, but it's worth noting both. No driver size breakdown, connector type, or original price has surfaced in the available documentation.
Surviving information on this model is otherwise sparse. It appears in the Dynacord 1975 catalog and circulates occasionally in the used pro-audio market — one European dealer listed a second-hand unit at €59. It's an honest little PA speaker from an era when Dynacord was expanding its professional lineup, and that's about all the record supports.
