EPI 70C

Almost nothing is documented about the EPI 70C. The EPI 70 does show up in period advertising (HI‑Fi‑Stereo‑Buyers, September 1978, p.27). The model name suggests a variant of the EPI 70, a bookshelf speaker that appeared in ads alongside EPI’s car audio line (HI‑Fi‑Stereo, August 1978, p.65) and in HI‑Fi‑Stereo‑Buyers (September 1978, p.27). Those ads were placed by EPI to promote the LS70 car speaker as “modeled after” the home EPI 70. They list the EPI 70 with a frequency response of 60-20 kHz, a crossover at 1800 Hz, and nearly hemispherical dispersion (HI‑Fi‑Stereo‑Buyers, September 1978, p.27). No source examined here records whether the “C” suffix means a cosmetic revision, a different cabinet finish, or a minor circuit change.

If you own an EPI 70C or have come across original literature, the Archive would welcome a note.
