Infinity RS-62K
Documentation for the Infinity RS-62K is thin, and the model name is ambiguous. Period sources refer to an “Infinity RS 6 K” - the smallest floorstanding speaker in the Kappa RS series (Audio, May 1988, p.124 describes the related RS 693k and RS 63k). The RS-62K designation, if it genuinely differs, may come from a variant, a regional badge, or a cataloging inconsistency. What follows is what the record shows for the RS 6 K, which is the nearest confirmed match.
The RS 6 K is a three-way, bass-reflex floorstander with a front-ported enclosure. It uses Infinity’s proprietary EMIT (Electromagnetic Induction Tweeter) with a ribbon-like diaphragm. The midrange and woofer drivers have polypropylene cones. Rated sensitivity is 92 dB (2.83 V/1 m) into 8 ohms, and frequency response is given as 38 Hz - 40 kHz (±3 dB). Crossover points are 400 Hz and 4.5 kHz. Power handling is 100 W RMS (200 W music). Each cabinet measures 300 × 985 × 350 mm (W×H×D) and weighs 22.5 kg.
The original retail price was approximately US$1,650 (or DM 2,600) around 1995. The Absolute Sound reviewed the model and described the sound as surprisingly coherent for a high-end speaker, with good bass for its size and a smooth blend across the frequency range. The RS 6 K is reported to be rare on the used market, with typical asking prices of €500-800 as of 2023.
