Infinity 1001

Surviving documentation on the Infinity 1001 is thin. What the record shows: an equipment-directory entry in High Fidelity (1981, p.246) lists it as a three-way system of separate speakers — woofer, midrange, and tweeter intended for independent placement — with flush mounting, which points toward Infinity's component car-audio line of the early 1980s rather than their home loudspeakers. The same entry gives total system response as 35 Hz to 20 kHz, sensitivity as 100 dB SPL at one watt at one meter, and notes an air-suspension woofer with a voice coil.

Beyond that listing, almost nothing else is recorded. A 1972 Infinity advertisement in High Fidelity (October 1972, p.112) asked why the company used a 12-inch woofer in its $139 speaker; whether that speaker was the 1001 is not clear from the surviving text. No original price, production years, or independent review measurements for the 1001 have turned up in the archive.
