Overview: The Boston Acoustics
DSi460T2 is an in-wall speaker with a stereo input. It can be configured in two
ways: to play stereo from a single location when there's not enough room for a
pair of speakers in the wall or ceiling, or as a single input surround speaker
with a selectable direct or diffuse sound field.
Woofers: The DSi460T2 uses a dual voice coil, 6-1/2" DCD (Deep Channel Design) copolymer woofer. The DCD woofer uses a deeply grooved
pole plate that enables the voice coil to travel farther for greater output
Tweeters: The DSi460T2 has dual 1" Kortec soft dome tweeters
set at different angles. 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. The soft, self-dampening top layer eliminates
unwanted resonance to make the sound smooth and articulate.
The DSi460T2 is well suited for humid environments like the kitchen or bathroom.
It should be mounted in a position where the speaker will not collect moisture.
Inputs: Spring loaded posts
will accept pin connectors, single and dual banana plugs, or bare wire up to 12 gauge.
Wiring Options: If the speaker
is to be used as a single stereo speaker, you should set the input jumper to the
Dual Input setting. (The jumper is located on the back of the speaker.) You can
then connect the speaker wires to the Input A and Input B terminals. If the
speaker is to be used as a surround speaker, you should set the input jumper to
the Single Input setting, and connect the speaker wires to the Input A terminals
only. As a surround speaker, you can select the direct or diffuse mode via the
2-way switch on the front of the speaker.
Note: When the speaker is connected as a Single Input it
presents a 4-ohm load to the amplifier. When wired as a Dual Input, the
speaker's impedance is 8-ohms.
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 scrim. IR will work best in on-axis to the face of the
Installation: After a
10" x 7-3/8" 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 clamps. The clamps spread up to 2.270", so they should cover
almost any application (most drywall is 1/2" thick). The required depth to
install this speaker is 3.481".
Note: There must be 1 1/2"
clearance around the mounting hole on the short axis to accommodate the clamps.
New Construction Bracket: For
new construction installation, the NCB6 bracket (item # 065NCB6) is required.
Paintable: Both the frame and
grill can be painted to match the ceiling or wall. A plastic paint shield is included to protect
