Product Information
Full details
This 8-inch 100V line ceiling speaker by Pulse Plus (model PLS00556) is designed for environments requiring clear background music and announcements. Its key benefit is a wide frequency response delivering rich audio, but its 100V line operation means it requires a compatible amplifier system. The speaker features a 30-watt power handling, a coaxial 2-way design with a 1.5-inch tweeter, a flush-mounting ABS baffle, and a magnetic speaker grille for a sleek, modern installation.

FAQs
What type of amplifier do I need for this speaker?
You need a dedicated 100V or 70V line amplifier. This speaker is not compatible with standard low-impedance (4-8 ohm) amplifiers.
How do I choose the correct power tapping?
The power tapping (e.g., 30W, 15W, 7.5W) determines how much power the speaker draws from the amplifier. Lower tappings provide less volume but allow more speakers to be connected to the amplifier. Higher tappings provide more volume. Choose a tapping that balances desired volume with the amplifier's total capacity and the number of speakers in your system.
Can I mix 100V and 70V systems?
No, you must use either a 100V system or a 70V system throughout. Do not mix these systems together, as it can lead to damage or improper operation.
What is the frequency response of this speaker?
The speaker has a frequency response of 60Hz to 20kHz, providing a broad range for both bass and treble frequencies.
How do I install the speaker grille?
The grille attaches magnetically. Simply align it with the speaker baffle and it will snap into place. To remove, gently pull it away.
What is the SPL (Sound Pressure Level) of this speaker?
The SPL is 94dB measured at 1 Watt of power at 1 meter distance.
Can this speaker be used outdoors?
This speaker is designed for indoor use. It is not weather-resistant and should not be exposed to rain or direct moisture.
Troubleshooting
No sound from the speaker
Verify that the amplifier is powered on and functioning correctly. Check that the speaker is properly wired to the 100V/70V output of the amplifier and that the correct power tapping is selected on the speaker's transformer. Ensure the amplifier is set to the correct mode (100V/70V).
Distorted or crackling audio
Check speaker wiring for loose connections. Ensure the selected power tapping on the speaker is not exceeding the amplifier's output capability or the speaker's maximum rating. Reduce the volume output from the amplifier. Inspect for any physical obstructions around the speaker cone.
Low volume output
Increase the volume on the amplifier. Select a higher power tapping on the speaker's transformer (ensure it does not exceed amplifier capacity). Verify that the total wattage of all connected speakers does not exceed the amplifier's rated power output. Check for any impedance mismatches if using a mixed system.
Speaker won't stay securely mounted
Ensure the dog-ear clamps are fully rotated outwards and are screwed down tightly against the mounting surface. Check that the mounting surface is suitable (e.g., not too thin or brittle) for the clamps to grip effectively.
Pros and Cons
Pros
- Wide frequency response for clear audio playback.
- Versatile 100V/70V line operation for flexible system integration.
- Easy installation with dog-ear clamps and magnetic grille.
- Sleek, low-profile design that blends into most environments.
- Durable ABS baffle and metal grille construction.
Cons
- Requires a 100V/70V amplifier, not suitable for standard low-impedance systems.
- Fixed power tappings may not suit all specific wattage requirements.
- Installation depth might be a consideration in very shallow ceiling spaces.
- No built-in volume control or adjustable EQ.
- Primarily designed for background audio and announcements, not high-fidelity critical listening.
Setup, Compatibility & Care
Setup:
- Determine Placement: Choose a location in the ceiling or panel that allows for optimal sound distribution and is free of obstructions.
- Cut Opening: Use the speaker's dimensions to mark and cut an appropriate hole in the mounting surface.
- Connect Wiring: Connect the speaker's transformer wires to your 100V or 70V amplifier output. Select the desired power tapping on the speaker's transformer based on your system's requirements and desired volume level.
- Secure Speaker: Rotate the dog-ear clamps outwards and screw them down to secure the speaker firmly into the ceiling/panel.
- Attach Grille: Align the magnetic grille over the speaker and ensure it snaps into place.
Compatibility:
- This speaker is designed for use with 100V or 70V amplifier systems. It is not compatible with standard low-impedance (4-8 ohm) amplifier outputs.
- Ensure your amplifier has sufficient power output to drive the number of speakers connected at their selected wattage tappings.
Care:
- Keep the speaker grille clean. Gently wipe with a soft, dry cloth to remove dust. If necessary, use a slightly damp cloth, ensuring no moisture enters the speaker driver.
- Avoid exposing the speaker to excessive moisture, extreme temperatures, or direct sunlight for prolonged periods.
- Periodically check connections to ensure they remain secure.
