2-way wired speaker FBT Project 550, 50 W RMS, 80–20000 Hz, 8 Ω, 89 dB sensitivity, Black

FBT Project 550 is a 2-way wired speaker designed for versatile installation use. The passive loudspeaker houses a 5" woofer and a 0.75" tweeter in a compact ABS enclosure finished in black. It delivers 50 W RMS continuous power with a frequency response covering approximately 80–20,000 Hz and an 8 Ω nominal impedance. The speaker includes a Euroblock connector for wired connection, an adjustable output tap for 100 V line use, and a fully adjustable support bracket with safety cable for straightforward mounting in venues, rehearsal rooms or background sound applications.

Advantages

The Project 550 combines a compact two-way design and lightweight construction (approx. 2.3 kg) to simplify installation and positioning. Its passive crossover and two-driver configuration provide clear voice intelligibility and a balanced sound across the mid and high range. The adjustable support bracket and Euroblock connection reduce installation time and allow secure, permanent mounting. Built with an ABS cabinet and finished in black, the speaker is suitable for visible installations where a discreet appearance is required.

How to use

Mount the FBT Project 550 using the supplied adjustable bracket and secure the safety cable to a fixed anchor point. Connect the speaker to an appropriate amplifier or 100 V line using the Euroblock connector, observing polarity. Set the output tap or attenuation switch as required for the installation and the amplifier power rating; recommended amplifier power is up to 100 W RMS with long-term power matching at 50 W. Position the speaker to optimise coverage and speech intelligibility, and verify levels at listening positions to avoid clipping or distortion.

Usage recommendations

For best performance, use an amplifier with suitable headroom (recommendation up to 100 W RMS) and apply a low-cut filter around 50 Hz when installing in small spaces to protect the woofer and reduce unwanted low-frequency build-up. Regularly check the Euroblock connection and the bracket fastenings after installation.
