Infinity RS-2B

The Infinity RS-2B has a thinner paper trail than it should. It was part of Infinity's Reference Standard series, and it was closely tied to the RS-2A. The two share a single service manual, titled "REFERENCE STANDARD2A/2B," revised September 1998. Infinity Systems, Inc. of 250 Crossways Park Dr., Woodbury, New York issued it, and it is the most solid documentation the RS-2B has.

Past that, the record is mostly parts listings and forum chatter. Replacement grille emblems exist for the RS-2B. They are compatible with the RS-2A and RS-IIB, and they are sold as a two-piece set for roughly $16 - $44. An EMI midrange casing is shared across the RS-1B, RS-IIB, RS-2B, and IRS Beta. Foam surround kits and crossover replacements turn up on the used market too. A crossover pair was listed at $200 on US Audio Mart, and a foam kit for the RS-2A/RS-2B went for €52 on eBay Italy. So the RS-2B was a real, serviceable speaker with a following. None of that says how it sounded.

The name is a mess. The RS-2B is sometimes written "RS IIB" or "RS-2-B," and it's not clear whether those are the same speaker or a variant. A Polk Audio Forum poster suggested searching "RS IIB" instead of "RS 2B" for better results, so the confusion has been around a while. This page uses the name as it appears in the service manual, RS-2B. Anyone hunting for one should try both spellings.

Still missing: frequency response, impedance, power handling, driver complement, dimensions, and original price. No production years. No period reviews with substantive detail. Anyone with a pair, the manual or any specs can send them to the Archive.
