The Monacor NR‑22KS is a compact horn speaker designed for public address applications, delivering clear and assertive sound within the 600-7,000 Hz frequency range. Featuring moisture‑proof construction and an 8 Ω impedance, this speaker is particularly well suited to wall mounting in both indoor and protected outdoor settings.
Housed in a durable white plastic shell, the NR‑22KS features an ABS enclosure that is moisture‑proof (though not fully waterproof), ensuring reliable performance in environments shielded from splashes and drips. The unit is supplied with a sturdy mounting bracket for easy wall installation and maintains an operational ambient temperature range of 0-40 degreesC.

Q: Is this speaker suitable for outdoors?
A: It is moisture‑proof and can be used outdoors if shielded from direct rain and heavy moisture.
Q: What output impedance should my amplifier have?
A: The amplifier should match the 8 Ω impedance of the speaker to avoid a mismatch.
Q: Does it come with mounting hardware?
A: Yes, a wall‑mounting bracket is included for straightforward installation.
Q: What kind of environments is it best suited for?
A: Ideal for indoor or sheltered areas where some moisture resistance is needed, but not for exposure to heavy rain or direct water jets.
Q: Can multiple units be connected to one amplifier?
A: Yes--just ensure the combined impedance does not drop below the amplifier's minimum load and ensure correct polarity.
