ECLER NIC-6

Product overview

The ECLER NIC-6 is a two-way in-ceiling / in-wall loudspeaker for 70/100 V line and low-impedance installations, delivering 50 W RMS from a 6.5 inch woofer and a 1 inch steerable dome tweeter for precise, high-intelligibility coverage.

Its built-in line transformer has practical taps (100 V: 50 / 25 / 12.5 W; 70 V: 25 / 12.5 / 6.25 W) plus 8 Ω operation. The NIC series ART (Acoustic Resonator Technology) back can reduces low-frequency distortion, connections and power selection are reachable from the front even after installation, and the IP66-rated speaker has a magnetic frameless grille with a removable logo.

ART back can

ART, validated by laboratory measurements, reduces low-frequency THD for cleaner, more transparent sound, and minimises resonance and coloration in false ceilings.

Front access

Pull off the magnetic grille and remove the tab to reach the 4-pin Euroblock and the selector: wiring and tapping can be changed without taking the speaker down. ECLER recommends a 100 W RMS amplifier.
