The NCL range of ceiling speakers are equipped with high-quality two-way speakers that provide exceptional sound quality even for message transmission. The stylish flat grille provides component invisibility, especially in rooms where a discreet ceiling architecture is required. The system of attaching the folding ear loops allows for easy and quick installation of the speakers. The speakers can be connected to a high-impedance distribution of 70V or 100V, and the rotary switch can be used to select the taps of the transformer and thus reduce the volume (power) of the speaker. The internal four-pin terminal block allows serial or parallel switching of speakers. Operation with an internal impedance of 16Ω is also possible. The speakers comply with the European standard EN 54-24 / 2008; Certificate No. 1438-CPR-0696 for indoor fire and evacuation radio.
The range includes two models NCL-4 and NCL-6 differing in power and diameter of the subwoofer. The NCL-6 model is for a maximum output of 60W and consists of a 6.5" (160.6 mm) conical woofer and a coaxial dome 3/4" (19 mm) tweeter.
1 pc = 1 pair of speakers Can only be ordered in pairs.
