Marantz AR-3
The Marantz AR-3 is one of those models where the surviving record is thinner than it deserves to be. What we know with reasonable confidence: it was a two-way bookshelf loudspeaker in a bass-reflex enclosure, part of Marantz's "Dynamic Audio" speaker line. Classic Audio's documentation gives the most complete picture — a 10" LF driver, crossover set at 4 kHz for the midrange and tweeter, and a high-frequency attenuator control on the cabinet. The same source lists the frequency range at 55 Hz–20 kHz, sensitivity at 92 dB/W/m, and power handling from 12W RMS up to 30W continuous music power, with 40W RMS permitted when the highs attenuator is set halfway. A capacitor handles HF compensation.
The sources disagree on nominal impedance. One says 8 Ω with a lower B/E switch, while an eBay listing gives both 6 Ohm and 8 Ohm. No production years, original price, dimensions, or weight have turned up in any documentation consulted. Don't confuse the AR-3 with the Acoustic Research AR-3a. Despite the similar name, it's a separate product.

- Crossover: 4 kHz
- Frequency range: 55 Hz – 20 kHz
- Sensitivity: 92 dB/W/m
- Power handling: 12W RMS to 30W continuous (40W RMS max with attenuator at half)
- Impedance: 8 Ω nominal (one source also lists 6 Ω)
If you own a pair or have original literature, the archive would welcome the details.
