Great sound, professional look

The audio quality is crisp and clear, ideal for background music and announcements. The white grille blends seamlessly into our office ceiling. Only minor issue was the cut-out template could be slightly more precise.

Superior coaxial clarity

The coaxial driver really makes a difference in how the sound fills the room. No harsh highs or muddy lows. We opted for the custom manufacturing option to get our logo on the grille, and the result was perfect.

Good performance, easy install

Installed these in a conference room. The voice clarity is outstanding for paging systems. The paintable grille is a nice touch to match custom ceiling colors. Would recommend for any commercial space.

Excellent value for commercial use

Purchased 24 units for a retail store. The ability to switch between 70V and 8Ω made wiring very flexible for our specific layout. Sound quality exceeds expectations for this price point.

Reliable and durable

These speakers have been running in our gym lobby for six months now without any issues. They handle high volumes well without distortion, and the build quality feels very robust.

Perfect for our restaurant renovation

We installed the 30W version throughout our dining area. The coaxial design provides excellent sound dispersion, ensuring even volume without dead spots. Installation was straightforward with the included spring clips.

5 FAQ

Q: Can these speakers be used in a bathroom or high-humidity area?

A: While these speakers are built with durable materials, they are not IP-rated for direct water exposure. For standard bathroom ceilings away from showers, they are generally suitable, but we recommend our IP-rated series for saunas or shower areas.

Q: Is the custom manufacturing available for small orders of 10 units?

A: Custom branding usually requires a minimum order quantity (MOQ) of 50 units. However, for color matching the grilles, we can accommodate smaller batches. Please reach out to our sales team for specific requirements.

Q: Do I need a separate amplifier for the 70V mode?

A: Yes, you will need a constant voltage amplifier compatible with 70V or 100V lines. The internal transformer in the speaker handles the voltage step-down, but the source amp must support high-impedance outputs.

Q: What gauge wire do you recommend for a 40-meter run?

A: For a 40-meter run in a 70V system, we recommend using 16 AWG or 14 AWG speaker wire to minimize power loss and ensure consistent volume across all speakers in the zone.

Q: What is the maximum ceiling thickness these can mount to?

A: The mounting springs accommodate ceiling panels ranging from 5mm up to 25mm in thickness. If your ceiling is thicker, please contact us for extended spring clip options.
