About the Boston Acoustics DSi453
The DSi453 from Boston Acoustics, sold individually, delivers high-performance sound, and it installs directly into your wall, so it doesn't take up an inch of floor space. It features a 1" tweeter for clear highs, plus dual 5-1/4" woofers for rich mids and lows. Pick up a pair if you want great stereo sound, or put together a complete "stealth" home theater speaker package. The DSi453's rectangular shape means you can position it vertically for front and surround speakers, or horizontally for use as a center channel speaker. And it's perfectly matched to all Boston Acoustics in-wall and in-ceiling speakers, so you can mix and match them to create the system that's ideal for your room and tastes.

Product Research
Features
Woofers: The DSi453 uses dual DCD Copolymer 5-1/4" woofers.
Tweeters: The DSi453 is equipped with a 1" Kortec soft dome tweeter. Kortec is a silky fabric saturated on the underside with a proprietary stiffening agent. Because the inside surface of the dome is ultra stiff, the tweeter tracks the signal with ease and produces an excellent transient attack. Simultaneously, the soft, self-dampening top layer eliminates unwanted resonance, so the sound is smooth and articulate.
Inputs: Spring loaded posts will accept pin connectors, single banana plugs, or bare wire up to 12 gauge.
Paintable: Both the frame and grille can be painted to match the wall or ceiling. A paint shield is included to protect the speaker.
IR Sensor Knockout: The speaker has a knockout molded into the speaker baffle that will accommodate a standard 1/2" diameter infrared sensor. The IR sensor range and operating angle will be reduced by the grille and cloth. IR will work best in on-axis to the face of the speaker.
Moisture Resistant: The DSi453 is well suited for humid environments like the kitchen or bathroom.
Installation: After a 14-1/4" x 7-5/8" cutout is made (either vertically or horizontally), the speaker is installed in the hole and held in place by a rugged plastic screw-set bracket. The only tool required (after the hole is cut) is a #2 Phillips head screwdriver to tighten the bracket. The bracket can spread up to 2.633", so they should cover almost any application (most drywall is 1/2" thick). The required depth to install this speaker is 3.195".
New Construction Bracket: For new construction installations, the NCBTL5 bracket (item # 065NCBTL5) is required.
Note: There must be 1-1/2" clearance around the mounting hole on the long axis to accommodate the clamps.
