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.
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.

Technical Specifications
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.
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.
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 |
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.
