Our patented Ceramic Metal Matrix Diaphragm (CMMD™) drivers, precision dividing networks and rigid, heavily braced enclosures combine to deliver uncompromised performance in any stereo or multichannel home theater system.The Beta ES250 is the perfect surround loudspeaker to complete any home theater system.
IMPORTANT NOTE: The set of drivers closer to the monopole setting indicator in Figure 3 should be installed toward the front of the room. It does not matter whether the tweeter is positioned above or below the woofer.This will ensure proper operation and performance should the Monopole or Dipole position on the surround mode configuration switch be selected.

WIRING THE SYSTEM IMPORTANT: Make sure all equipment is turned off before making any connections. Applications 1 and 2 (one channel shown) For speaker connections, use a high-quality speaker wire with polarity coding.The side of the wire with a ridge or other coding is usually considered positive polarity (i.e., +). Heavier-gauge wire should be used when more than 50 feet (15m) of speaker wire is required.The wire channels on the rear of the Beta ES250 will accommodate most types of 14- to 18-gauge wire.
WALL-MOUNTING The Infinity Beta ES250 speaker is designed to mount directly to a wall. Each speaker has (4) keyholes in the rear to allow either left- or right-side placement. Each speaker will require (2) 1-1/2" (38mm), #8 wood screws fastened to a wall stud. If a wall stud is unavailable, install an anchor appropriate for a 1-1/2" (38mm), #8 screw. Use the supplied template to accurately position the screws on the wall and refer to the diagrams for more assistance.
FINAL ADJUSTMENTS CARE OF YOUR SPEAKER SYSTEM Check the speakers for playback first by setting the system volume control to a minimum level, and then by applying power to your audio system. Play a favorite music or video segment and increase the system volume control to a comfortable level. The Beta ES250 does not require any routine maintenance. When needed, use a soft cloth to remove any fingerprints or dust. NOTE: You should hear balanced audio reproduction across the entire frequency spectrum.
