EPI 400
Little is documented about the EPI 400. What survives comes almost entirely from a single period advertisement.
EPI's own advertising in High Fidelity (August 1973, p.89) put the 400 in the middle of the company's lineup. The ad called it "The Mini Tower" and listed the price at $389. It set the 400 against the flagship Model 1000 at $1000 and the entry-level Model 50 at $55, so the 400 was clearly a mid-range model. The surviving ad copy cuts off before any technical specifics. No driver complement, dimensions or frequency response appear in the available record.
No production years, design details or contemporary reviews have surfaced in the documentation examined. The EPI 400 is confirmed mainly by this single 1973 reference.
