Acoustic Research AR-48s (circa 1982)
Documentation on the AR-48s is scarce. The Archive's files hold no factory spec sheet, no manual, and no pricing for this Acoustic Research loudspeaker. What survives from the period is a single test report.
High Fidelity (May 1982, p.27) reviewed the AR-48s and recorded an impedance of 6.4 ohms using a pink-noise signal band-limited to 250 Hz–6 kHz, a supplementary measurement the magazine was just beginning to adopt alongside standard impedance sweeps. The review's closing thought on the sound was characteristically direct: the most concise way to describe the AR-48s's listening quality was that it kept out of the way of the program.
Everything else - driver complement, crossover points, cabinet dimensions, original price - isn't documented in the surviving record.
- Measured impedance: 6.4 ohms (pink noise, 250 Hz–6 kHz; High Fidelity, May 1982)
