Stereo Driver Design: The Boston Horizon HSi 475T2 in-wall speaker utilizes a stereo driver design, featuring two 1" Kortec soft-dome tweeters for crisp, high frequencies and a dual voice-coil 6.5" DCD copolymer woofer for accurate midrange/midbass performance.
- Two 1" Kortec Soft-Dome Tweeters: Boston's exclusive Kortec tweeter utilizes a silk-like dome backed by a stiff material to provide smooth high-frequency reproduction and stability at high volume levels.
- Dual Voice-Coil 6.5" DCD Copolymer Woofer: The Deep Channel Design (DCD) woofer uses a deeply grooved pole plate that enables the voice coil to travel farther for greater output without bottoming out. The woofer cone is made of a copolymer material with a butyl rubber surround for solid midbass performance.
Stereo Inputs: The HSi 475T2 can be used to play stereo from a single location when there is not room in the wall for a pair of speakers. There are spring-post terminals for both left and right channels. These two inputs feed the two separate tweeters and the woofer's two voice coils. The result is stereo sound in a location where you only want to mount one speaker. The two sets of spring-post terminals will accept bare wire (up to 12AWG) and banana plugs (single or dual).
- There is a jumper wire on the back of the speaker which needs to connected to the "Dual Input Setting" connector on the back of the speaker, if you are going to use the HSi 475T2 as a single stereo speaker. Out of the box, the jumper wire is connected to the "Single Input Setting" connector for mono operation.
- You will need to connect both sets of binding post terminals to your amplifier (one to the right channel and one to the left channel), when using the HSi 475T2 as a single stereo speaker. You only need to connect one set of binding post terminals (labeled "Input A") to your amplifier when using the HSi 475T2 as a mono speaker.
- Configured as a single stereo speaker and using both inputs, the HSi 475T2 is rated at 8-ohms. Configured as a mono speaker and only using one input, the HSi 475T2 is rated at 4-ohms.
Direct & Diffuse Operating Modes: When using the HSi 475T2 as a surround speaker, it can be configured in either direct or diffuse mode (switch found on front baffle behind the grille). In direct mode, the speaker has an even dispersion pattern in all directions. In diffuse mode, a "null" is created at the base of the speaker.
Reduced Bezel Design with Magnetic Grille: Boston's unique slim bezel design provides interior designers and consumers the look that blends with a room's distinctive design. The slim bezel design also offers an installer-friendly wide mounting flange to cover any imperfections in the cutout hole and magnetic grilles for easy finish work.
Note: Both the frame and grille can be painted to match the wall. A plastic paint mask is included to protect the speaker from being painted as well.
In-wall Installation: The Boston Horizon HSi 475T2 installs in a 8.8125" (w) x 11.5625" rectangular cutout opening. The required depth to install the in-wall speaker is 3.5" from the mounting surface. Behind the opening there must be a 1.5" clearance around the top and bottom of the cutout and speaker to accommodate the included mounting bracket. The mounting bracket secures the speaker tightly in place. The wall material should be at least 1/4" thick.
- If the HSi 475T2 is going to be used as the only speaker in a small or midsize room, hallway, or bathroom, position the speaker as close to the center of the room as possible. This will allow the speaker to provide the most even distribution of sound.
- The NCB6 new-construction bracket (sold separately) can be used to simplify installation in new construction.
IR Sensor Knockout: The HSi 475T2 in-wall speaker has a knockout molded into the speaker baffle that will accommodate standard 0.5" diameter infrared (IR) sensor.
