History

The EPI 201 - and its stablemates, the Epicure 20 and Epicure 20+, were Winslow Burhoe's best early attempts to get his speakers to "blend in" to the room using his "module" design of woofers and tweeters that were engineered to complement each other. These featured an eight inch woofer and one inch concave dome tweeter on both the front facing baffle and a precisely angled top panel. Designed to be placed against the wall, and on the floor, the sound would simply wrap up and around the cabinet and flow into the room.

The following is copied from the "Brown Booklet", which refers to the speaker throughout the text as "The Quartet":

The EPI Quartet is a high fidelity loudspeaker of unmatched quality and convenience. It is characterized by a linear, nondirectional frequency response over the entire audio bandwidth. At the same time, The Quartet offers extremely flexible room placement through a new and functional cabinet design.

Each EPI woofer and tweeter complement, or "module", provides a full range of undistorted sound reproduction. In the interest of improving power handling and dispersion, The Quartet utilizes two of these modules.

As in all loudspeaker systems devoted to high fidelity performance, the cabinet design is an integral part of The Quartet's performance. The multifacet design of The Quartet's cabinet permits placement of the two modules in different planes. One of the modules is positioned in an upward plane to minimize sound absorption from rugs and to increase the dispersion. The other module is mounted in the front facing plane.

As a byproduct, the optimum positioning of the speaker is remarkably easy to achieve in any room due to the location of each module in the cabinet. When the speaker is placed at the point where any two surfaces meet (on the floor against a back wall), the correct balance in acoustical output between woofer and tweeter is maintained. Additional benefits of the highly desirable effect of reverberent field are achieved when the speaker is placed adjacent to an additional reflective surface, for example a side wall.

The Quartet is a pleasant contrast to other speakers which provide sound reproduction from only one radiating source. The Quartet's omnidirectional bi-module concept may be placed upright, on its side, or on its back, near the floor or ceiling, with no degradation to sound quality. Its dispersion is so wide and so uniform that stereo definition is unaffected, regardless of speaker and listener positioning.

The sound of the EPI Quartet is completely open and natural. All tones and instruments are reproduced with superb accuracy. The lower register is clean and authoritative, extending to cover the lowest transients below the range of audibility. The upper portions of the frequency spectrum come alive in a very special way.

Ask any EPI listener, they'll tell you what we mean.
