The QRI-404 is a slim, passive 2.5-way full-range loudspeaker in an elegant column design, part of the QRI 400 series. It is purpose-built for clear and natural reproduction of speech and music in acoustically sensitive environments such as restaurants, conference and training rooms, museums, churches, and small theaters.

Equipped with four 4˝ full-range drivers and a centrally positioned 1˝ dome tweeter, the QRI-404 delivers balanced sound with excellent vocal clarity and smooth high-frequency response. Its 2.5-way design ensures an even frequency response and dynamic performance, especially when paired with a dedicated subwoofer such as the QRI-108 S.

The speaker supports 200 W RMS (400 W Peak) power and delivers up to 113 dB SPL with a sensitivity of 90 dB (1W/1m). Its vertical column form factor and 80° x 40° dispersion make it ideal for focused sound distribution in elongated spaces. The 16-ohm passive design and dual Speakon/Phoenix connections offer great integration flexibility.

Mounting is made easy with optional swivel U-brackets that allow both horizontal and vertical installation. Custom RAL colors are available on request for seamless visual integration.
