Overhead stereo sound from Niles
Overhead stereo sound from Niles
Want background music in a room where space is tight? The Niles DS7Si in-ceiling speaker is a great choice for dynamic stereo sound from a single overhead location. You'll enjoy clear mids and solid bass from the 7" glass fiber woofer, and smooth highs from two 1" soft dome tweeters.
Listen to music in nearly any room
Use the DS7Si in areas where a pair of in-ceiling speakers may be impractical, such as hallways, entryways, small offices, or walk-in closets. Its moisture-resistant design makes it a great option for your bathroom, kitchen, garage, or covered porch. Niles's Directed Soundfield™ technology lets you pivot the woofer to aim the sound toward your listening position.

Features
2-Way Stereo Driver Array: The Niles DS7SI in-ceiling speaker utilizes a 2-way driver stereo array, featuring two 1" UltraSilk tweeters and one 7" Glass-Fiber cone woofer with dual voice-coils, for a spacious stereo sound from a single speaker.
Pivoting Driver Design: The entire 2-way driver stereo array (including the two tweeters and woofer) pivots so you can direct the sound to the listening area. The pivoting driver array adjust approximately 15 degrees.
Stereo Input: The Niles DS7SI is outfitted with two sets of speaker terminals which allow the DS7SI to be used as a single stereo speaker. The two sets of spring-post terminals accept bare wire (up to 10AWG), banana plugs (sing/dual), and angled pin-connectors.
MicroThin Grille: The magnetically attached MicroThin grille ensures a clean and virtually invisible appearance that blends with your room's aesthetics. The MicroThin grilles protrudes only 0.25" from the ceiling.
Moisture-Resistant Construction: Moisture-reistant construction enables installation in moist areas, such as bathrooms.
In-Ceiling Installation: The Niles DS7SI requires round cutout in the ceiling that measures 10.0625" (diameter) x 6.0625" (depth). Three spring tensioned mounting clamps secure the speaker in the wall and and compensate for uneven mounting surfaces. A 0.75" of clearance is required around the inside of the cutout opening to accommodate the mounting clamps. The mount clamps can support 0.5" to 1.0" thick drywall.
