Frequently Asked Questions - SP5NXCTUL Speco Technologies

What is the impedance of the SP5NXCTUL speaker?

The speaker has an 8 ohm low impedance and also includes a 70V/100V line transformer with selectable power taps (5W, 10W, 20W, 30W).

How do I install the SP5NXCTUL ceiling speaker?

Cut a hole of 8.5 inches in diameter, feed the speaker wire, connect to the terminals, and secure the speaker using the provided tile bridge or mounting tabs. Attach the grille after installation.

What is the power handling of this speaker?

In low-impedance mode (8 ohms), the speaker can handle 60W RMS. In high-impedance mode (70V/100V), it can handle up to 30W depending on the tap selected.

Can I use the SP5NXCTUL outdoors?

No, this speaker is designed for indoor use only. Exposure to moisture or extreme temperatures may damage the speaker.

What type of amplifier should I use?

You can use a standard low-impedance amplifier (8 ohms) or a 70V/100V distributed audio system amplifier. Ensure the amplifier's power does not exceed the speaker's rating.

How do I clean the speaker?

Wipe the grille and baffle with a dry, soft cloth. Do not use water or cleaning solvents, as they may damage the speaker components.

Is the grille paintable?

Yes, the white grille can be painted to match your ceiling. Use a thin coat of water-based paint and avoid clogging the perforations.

What is the frequency response of the SP5NXCTUL?

The frequency response is 70 Hz to 20 kHz, making it suitable for both vocal paging and background music.

Can I replace the driver if it fails?

Yes, the driver is replaceable. Contact Speco Technologies or an authorized service center for compatible replacement parts.

Frame Construction Ceiling Installation

1

Take the cutout template from the packaging box and punch out along the larger perforated circle. Place the cutout template against the bottom of the ceiling and trace the inside of it. Carefully cut out the ceiling material along the circle.

2

Remove the top cover to access the speaker connector. Attack the speaker wires to the 4-pole captive screw connector. Insert the 4-pole captive screw plug into the connector on back of the speaker. Install the conduit and secure the connections.

3

Replace the top cover and tighten the screws. Insert the speaker through the bottom of the hole in the ceiling.
