lecho Yotez” ENGINEERING DATA DESCRIPTION In the decade or more since the introduction of compact speaker systems, performance has improved dramatically through a series of subtle refinements in materials, engineering knowledge, and production techniques. The result of this continuing advancement has been pro- gressively better sound at ever lower costs, and the E-V FOURTEEN loudspeaker system is a case in point. An acoustic suspension woofer must have an extremely low free-air resonance so that the additional restoring force of the air sealed in the enclosure will raise the operating resonance to the desired frequency. The E-V FOURTEEN woofer has a free-air resonance of 25 Hz. A sealed, urethane foam half-roll surround maintains precise alienment of the cone without unnecessarily raising the resonance. From 1500 Hz to the limit of audibility, a special 2%-inch cone tweeter provides the sparkle and brilliance so necessary for satisfying musical reproduction. The use of a relatively large diameter cone maintains the neces- sary efficiency down to the lower limit of the tweeter's range. However, unlike some tweeters, the flat-cone geometry and aluminum dome maintain wide dispersion for complete coverage of the listening area. A deluxe LCR crossover controls the input to each of the drivers. and provides adjustment of high-frequency re- sponse to match listening room acoustics. The crossover and all components are tested individually, and then as a complete system, to assure laboratory standard per- formance. The E-V FOURTEEN enclosure integrates the require- ments for acoustical excellence with the techniques of fine furniture construction. All four sides are finished in genuine oiled walnut veneer to allow use in either vertical or horizontal position. The nameplate, which is held in place by an adhesive backing, may be repositioned for vertical placement. SPECIFICATIONS Frequency Response: 40 — 18,000 Hz Nominal Impedance: 8 ohms Power Handling Capacity, Program: 35 watts Peak: 70 watts Dimensions: 1344” H x 24” W x 11%” deep Finish: Oiled Walnut Veneer Net Weight: 32 pounds Shipping Weight: 42 pounds PLACEMENT The E-V FOURTEEN may be placed on a table, shelf or on the floor. Generally however, the most realism will be obtained if its height from the floor is equal to the listener's ear level. The E-V FOURTEEN performs equally well placed in a horizontal or vertical position. The above comments apply also to stereophonic place- ment. Additionally, however, the two systems should be far enough apart to permit listeners to sit at the apex of a thirty- to forty-degree angle, as illustrated in Figure |. A distance of six to eight feet between stereo speakers will, in most rooms, provide natural separation. Placing the loudspeakers 100 close together or listening at too great a distance will destroy the stereo effect, and the sound will be essentially monophonic. Extreme spacing between speakers or listening at too short a distance will produce exaggerated and unreal separation. In long rooms, the E-V FOURTEEN COMPACT LOUDSPEAKER SYSTEM NALSAS HAMYEdSANO1 LIVdINOO N3314NO4 A-3 loudspeakers should be placed along one of the short walls facing into the long room dimension. This improves bass reproduction and provides good stereo listening over most of the room. Peri К LISTENING POSITION SOUND BECOMES MONAURAL AT GREATER DISTANCES Figure 1 — Placement for Stereo AMPLIFIER CONNECTIONS The E-V FOURTEEN has a nominal impedance of eight ohms. Connections should be made between the right terminal and the amplifier 8-ohm terminal; the left terminal should be connected to the amplifier “common” terminal (sometimes referred to as “O” or "C”). Con- nections should be made with No. 18 or larger wire; common zip- or lamp-cord is satisfactory. If the speaker leads are to be run behind a molding strip or under a carpet, TV twin lead may be used. ADJUSTMENT OF BALANCE CONTROL The E-V FOURTEEN is equipped with a continuously- variable balance control to adjust the high-frequency response of the system to varying acoustical environ- ments. The “normal” position, indicated on the control, should be correct in most instances. Acoustically “hard” or “live” rooms may require a retarded setting of the control to compensate for the greater amount of high- “HOLE IN THE frequency reflection. In “soft” or “dead” rooms with MIDDLE" carpeting, soft furniture, and draperies, an advanced ss setting of the contro! will normally be required. The best guide to setting the control properly is a familiarity with the sound of live music. That position of the control which provides the musical balance most satisfactory to you is correct.
