1. E V SEVEN B COMPACT LOUDSPEAKER SYSTEM ElecheYorcx ENGINEERING DATA DESCRIPTION The Electro Voice Model E V SEVEN B system is a carefully designed two way reproducer offering out standing performance in an enclosure of surprisingly modest dimensions Lower distortion and wide frequency range are achieved by the use of two separate drivers each handling a special portion of the audible spectrum The component quality 8 inch woofer features such refinements as an Alnico V magnet precision wound voice coil and a linear suspension which allows long yet carefully controlled excursions Frequencies above 2000 Hz are handled by a three and one half inch specially constructed cone type tweeter which provides exceptionally smooth treble response without undesirable harshness Excellent high frequency dispersion insures lifelike realism especially when the E V SEVEN SB is used in stereo applications A two way electrical crossover provides smooth transition from one driver unit to the other Finest quality components including encapsulated inductors are employed for maxi mum power handling capacity and crossover frequency accuracy The attractive E V SEVEN B enclosure is rigidly con structed throughout and is handsomely finished in walnut on all four sides The nameplate may be rotated to permit either horizontal or vertical placement SPECIFICATIONS Frequency Response 50 to 15 000 Hz Nominal Impedance 8 ohms Power Handling Capac2. ISTENING POSITION SOUND BECOMES MONAURAL AT GREATER DISTANCES Figure 2 Placement for Stereo AMPLIFIER CONNECTIONS The E V SEVEN B has a nominal impedance of eight ohms Connections should be made between the left terminal T1 and the amplifier 8 ohm terminal the right terminal T2 should be connected to the amplifier common terminal sometimes referred to as O or C Connections 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 SEVEN B 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 frequency reflection In soft or dead rooms with carpeting soft furniture and draperies an advanced setting of the control 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 CUSTOMER SERVICE Your E V SEVEN B system has been packed to provide protection
