Infinity 2000 A (circa early 1970s)
Little is documented about the Infinity 2000 A as a standalone model. What the record shows comes almost entirely from contemporary audio magazines, which treated it as a serious high-fidelity loudspeaker, good enough to be called a reference standard in its price bracket. An ad in High Fidelity (March 1974, p.101) quoted the Hi Fi Newsletter as giving the 2000 A its highest rating and calling it "their standard in its price category" until the 2000 AXT succeeded it. That same ad noted the AXT offered about 5 dB greater efficiency than the 2000 A. So the original was a somewhat less sensitive design.
There is also a listening report from HiFI-Stereo (November 1971, p.46). The magazine kept a pair of 2000 As in its listening room for several months alongside comparably priced speakers. The reviewer called it "an uncommonly smooth, balanced, wide-range system" and noted "solid, almost palpable low bass output" even at low listening levels. That is high praise for a floor-standing speaker of that era. The same piece implies the 2000 A was a three-way or perhaps multi-driver design. The review mentions that measurements below 200 Hz were challenging, but the bass extension was confirmed by ear.
No official specifications have survived in the materials available to the Archive. That means no driver sizes, crossover points, impedance, sensitivity, dimensions or weight. The production years and original price are not confirmed either. The magazine coverage places the model in the early 1970s, likely 1971 through 1973, before the 2000 AXT replaced it. The 2000 A appears to have been Infinity's statement floor-standing speaker in that period, ahead of the better-documented 2000 AXT and 2000 II.
Known facts in brief:
- Floor-standing loudspeaker, early 1970s
- Described by HiFI-Stereo (Nov 1971) as smooth, balanced, wide-range, with strong low-bass output
- Rated as reference standard in its price class by Hi Fi Newsletter, per High Fidelity ad (Mar 1974)
- Succeeded by the Infinity 2000 AXT, which offered roughly 5 dB higher efficiency
- No confirmed specs: driver complement, crossover points, dimensions, weight, or price remain undocumented in available sources
