Not much is documented about the AR Acoustic TSW 610 beyond period equipment directories. Here is what the record shows. It was a floor-standing, three-way acoustic-suspension loudspeaker, listed in HiFi-Stereo in 1988 and again in 1989.
The drivers were a 12-inch woofer, a 6.5-inch midrange, and a 0.75-inch titanium-dome liquid-cooled tweeter. The tweeter sat on a Tetra-Helix plate, presumably a proprietary waveguide or baffle arrangement. The cabinet came in oiled walnut or oak with a black cloth grille. HiFi-Stereo (1988, p.141) gave the frequency response as 29-200 Hz ±2.5 dB. That almost certainly reflects a directory truncation or OCR error, since a full-range speaker of this design would extend well beyond 200 Hz. Sensitivity was rated at 96 dB SPL/W/m, minimum power at 15 W, and impedance at 8 ohms. Each speaker measured approximately 27 by 63 by 16 inches and weighed 150 lb. The listed price was $1,090 each.
That is about all that survives in accessible print. No production years, crossover details, or user impressions have been located.
