Our take on the Infinity Entra® Point Five

by Julie Govan
Infinity

Why choose a pre-matched speaker system?

Looking for speakers that'll deliver thrilling, edge-of-your-seat surround sound? Choosing a pre-matched speaker system is one way to ensure seamless home theater performance. These systems are made up of speakers that share the same tonal characteristics — that means the sound will stay consistent as it moves from speaker to speaker around your room. Most pre-matched systems come with a subwoofer — a must-have for high-impact bass.

Infinity took hot technology and used it to create a satisfying — and straightforward — speaker system! The Entra line incorporates design elements from Infinity's acclaimed high-end speaker lines — like the high-performance C.M.M.D. (Ceramic Metal Matrix Diaphragm™) drivers. And the Entra Point Five home theater system puts that great sound and design in a compact, pre-matched form.

Check it out. This room-friendly package includes four Entra Point Five satellites designed to work with the supplied Entra Center and Entra Sub. The compact, video-shielded satellites each team a 3/4" C.M.M.D. tweeter with a 4" C.M.M.D. woofer — you'll love the crisp, realistic highs and full mids. They're voice-matched to the video-shielded Entra Center, which uses a 3/4" C.M.M.D. tweeter and dual 4" C.M.M.D. woofers to handle the dialogue and on-screen effects. The Entra Sub holds up its end of the multichannel bargain beautifully; with a 150-watt RMS amp and 10" C.M.M.D. cone, it delivers beefy bass response to round out the system's sound.

The satellites, center and sub all share the same black ash vinyl finish, so they should blend smoothly into almost any decor. Keyhole slots on the satellites make wall-mounting easy.

Features

Components: The Infinity Entra Point Five HTS speaker system consists of four identical video-shielded satellites, a matching video-shielded center channel, and a 10" powered subwoofer. All speakers are perfectly timbre matched. The subwoofer is front firing and has a rear facing port.

C.M.M.D.: The Infinity Entra system uses Ceramic Metal Matrix Diaphragms. The light but rigid properties of these drivers deliver accurate musical reproduction, eliminating coloration due to cone breakup and dramatically reducing distortion. The C.M.M.D. drivers also don't tend to deteriorate when exposed to moisture, sunlight, or extreme temperature.

Satellite Mounting: The Entra Point Five satellite speakers are designed to be mounted directly to a wall. Each satellite speaker has a keyhole on the back and requires one 1-1/2" #10 wood screw fastened to a wall stud. If a wall stud is unavailable, install an anchor appropriate for a 1-1/2", #10 screw. These satellite speakers can also be placed on a shelf. 

Auto Power On/Off: The power to the subwoofer amplifier automatically turns on when it senses a program signal and turns off when no signal is present for about ten minutes.
