The QRI-404 T is the 100 V version of the elegant 2.5-way column speaker from the Pro-Sound QRI 400 series – perfectly suited for high-quality speech and background music reproduction in fixed sound installations. It performs exceptionally well in acoustically sensitive spaces such as restaurants, conference and training rooms, churches, museums, and small theaters.

Featuring four powerful 4˝ full-range drivers and a centrally positioned 1˝ dome tweeter, the QRI-404 T offers a transparent and balanced sound. Its 2.5-way configuration ensures smooth frequency response and excellent vocal clarity across the entire 100 – 20,000 Hz range. With 60 W RMS (400 W Peak) power handling, this speaker is ideal for use in 100 V public address systems and emergency notification systems (ENS), especially in setups with long cable runs or multiple speaker zones.

The 100 V version with 166 Ohms impedance allows efficient parallel operation of several speakers. Thanks to optional swivel U-brackets, the QRI-404 T can be mounted either horizontally or vertically. Custom RAL color finishes are available on request for optimal visual integration.
