Infinity RS-1000 (1977–1980)
The RS-1000 was the flagship of Infinity's RS series and the largest of the line. It was produced from 1977 to 1980. It's a three-way, ported design standing 42 inches tall and 17 inches wide, with a 15-inch woofer, a 5-inch midrange, and Infinity's planar-magnetic EMIT tweeter. The crossover uses polypropylene capacitors and air-core inductors. The cabinet came finished in walnut veneer. Rated sensitivity is 88dB with a 4-ohm impedance, and Infinity suggested amplifiers in the 25-150 watt range. Frequency response was specified at 40Hz to 32kHz.
Period coverage of the RS-1000 is thin. It appeared in a HiFI-Stereo (July 1986, p.130) new-products roundup alongside the smaller RS series models, though that listing called the RS-1000 a two-way system. That conflicts with the three-way driver complement documented elsewhere. The rest of the record is enthusiast reception. Reviewers praised the open, detailed midrange, while some noted a slightly rolled-off high end depending on the listening room. As with many of Infinity's larger speakers of this era, the EMIT tweeter is the component most likely to need attention today.
Surviving examples typically trade in the $450-$900 range depending on condition. The sources disagree on the exact crossover points (600Hz/4000Hz versus 650Hz/3800Hz), so treat either figure as approximate.
