Perfect for our conference room upgrade

The frameless design looks incredibly sleek in our new office ceiling. Sound distribution is even and the coaxial driver provides clear vocals for presentations.

Solid performance

Good clarity and no distortion at high volumes. The crossover network works well to separate frequencies. Deducting one star because the springs could be stronger.

Professional grade quality

Used these for a hotel lobby renovation. Guests have commented on how clear the announcements are without being intrusive. Highly recommended for commercial use.

Invisible yet powerful

Truly frameless appearance blends seamlessly into the drywall. Despite the compact size, the bass response is surprisingly good for background music.

Excellent value for venue audio

We installed twelve of these in a retail space. The constant impedance ensures consistent volume across all zones. Very impressed with the build quality.

Great sound, easy install

Installation was straightforward with the provided template. The 8-ohm impedance matched our existing amplifier perfectly. Only wish the grille was slightly easier to paint.

5 FAQ

Q: What gauge wire do you recommend for runs up to 50 feet?

A: For 8-ohm loads with cable runs up to 50 feet, we recommend using 16-gauge speaker wire to minimize signal loss and ensure optimal power transfer.

Q: Does this unit come with a back-can for fire rating compliance?

A: The standard package includes the speaker and grille. Fire-rated back-cans are sold separately to meet specific local building codes and fire safety requirements.

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

A: The mounting clamps are adjustable and can accommodate ceiling materials ranging from 10mm to 30mm in thickness.

Q: Can these speakers be used with a 70V distributed audio system?

A: No, the BT-418 is designed specifically for low impedance (8 Ohm) direct drive systems. For 70V systems, you would need an external step-up transformer or a model with a built-in transformer.

Q: Is the grille removable for painting before installation?

A: Yes, the steel mesh grille clips off easily. We recommend removing it to paint it to match your ceiling color before final mounting for the best finish.
