NORTHLINE NL6T 12W 70V/100V/8Ω Commercial Ceiling Speaker

12W IN-CEILING SPEAKER | 70V / 100V / 8Ω NORTHLINE NL6T Commercial Ceiling Speaker The NORTHLINE NL6T is a compact 12W in ceiling speaker designed for distributed background music and voice announcements. It gives installers a choice of 70V, 100V or 8Ω operation, making it adaptable to different commercial audio systems. Its 2 inch full range driver, white magnetic grille and black steel backcan suit ceiling installations where a discreet appearance and convenient system integration matter. Use it in reception areas, shops, cafés, offices, clinics and other shared spaces. Select the correct transformer tap for a 70V/100V amplifier, or use 8Ω bypass with a compatible low-impedance amplifier. The removable Euroblock connection and ceiling clamps help simplify installation. 12W Rated Power 70V / 100V / 8Ω 2" Full-Range Driver 162mm Cutout White Magnetic Grille Overview Features Specs Install & Load What's Included Manual Discreet Ceiling Audio for Everyday Business Spaces The NL6T is designed for spaces where music should be comfortably heard and routine announcements should remain intelligible without bulky wall-mounted equipment. Its white circular grille provides a tidy ceiling finish, while the steel backcan keeps the speaker assembly enclosed. For larger installations, 70V or 100V operation allows several NL6T speakers to run from a compatible distributed audio amplifier. Each speaker can be set to an appropriate transformer wattage tap. For a conventional compatible amplifier, the NL6T also offers 8Ω bypass. Retail & Reception Distribute background music through shop floors, service counters and customer waiting areas. Cafés & Dining Provide everyday background audio across smaller seating and service areas. Offices & Clinics Bring music or voice announcements to corridors, receptions and shared rooms. Hotels & Meeting Areas Keep the ceiling appearance clean in hallways, common areas and meeting spaces. Size Clarification: The NL6T uses a 2 inch full range driver inside a housing with a 192mm (7.6 inch) overall diameter. The 8Ω designation refers to the speaker's low impedance setting, not an 8 inch driver.

A 70V or 100V line must never be connected with the NL6T set to 8Ω bypass. Choose the Right Speaker Operating Mode The NL6T offers three modes so the same speaker model can be used with different types of properly matched sound systems. Select the appropriate setting before turning the amplifier on. 70V Commercial Audio Available taps: 1.5W, 3W, 6W and 12W. Ideal for multi-speaker distributed audio on a compatible 70V line. 100V Commercial Audio Available taps: 3W, 6W and 12W. Add the wattage taps of all connected 100V speakers. 8Ω Bypass Use with a compatible low impedance amplifier. Account for the combined impedance when connecting multiple speakers. Connection & Mounting Euroblock terminal, ceiling clamps and a removable magnetic grille support practical installation. Important: Do not connect the 8Ω bypass setting to a 70V or 100V amplifier output. Turn amplifier power off before wiring or changing the selector. Ceiling Preparation Checklist Confirm a 162mm (6.38-inch) ceiling cutout. Allow at least 95mm (3.7 inches) of mounting depth and check obstructions above the ceiling. Confirm ceiling material thickness does not exceed 39mm (1.5 inches). Connect the speaker cable, select the correct mode, then secure the speaker with its ceiling clamps and attach the grille. Turn on the system and test initially at low volume. 70V / 100V Speaker Load Planning In a distributed 70V or 100V installation, all speaker wattage taps add together. Keep the total connected speaker load below the amplifier's rated speaker-output capacity, with sensible headroom. Example: Eight NL6T speakers, each set to the 6W tap, create a total 48W speaker load. A compatible 60W amplifier leaves 12W of rated capacity unused. 8 × 6W Example speaker setting 48W Total connected load 12W Unused capacity on 60W amp Example Speaker Tap Calculations Speaker Quantity Tap per Speaker Total 70V/100V Load Amplifier Rated Power With 20% Headroom* 4 3W 12W At least 15W 6 6W 36W At least 45W 8 6W 48W At least 60W 10 6W 60W At least 75W 12 6W 72W At least 90W *Headroom Guideline: These amplifier calculations use an illustrative 20% power reserve; they are not manufacturer-specified minimum amplifier ratings. Always consider system design, speaker tap settings and other connected speakers. How Should Multiple NL6T Speakers Be Wired? For 70V or 100V installations, connect the speakers electrically in parallel and maintain consistent positive/negative polarity throughout the run. Refer to the manual for the illustrated connection method. Can I Use More Than One NL6T in 8Ω Mode? Yes, when the total connected impedance and wiring arrangement are compatible with the amplifier. Unlike distributed 70V/100V systems, do not choose an 8Ω speaker count based only on wattage-tap calculations. Installation Reminder: Match the speaker operating mode to the amplifier output, confirm polarity and wiring, and follow applicable electrical and building-code requirements.
