Design
The Infinity RS4 features an EMIT tweeter and Polydome midrange driver, characteristic of Infinity's proprietary driver technology from the era. The crossover design has been noted as interesting for a speaker of this class and age.

While the RS4.5 model is better documented, the RS4 appears to be a distinct model in the same lineage, produced during the early 1980s to mid-1980s.
