Overview
The Qi15 is the largest full range speaker in Quest's Qi Series, built for big rooms where a 12 inch box will not carry to the back: large church auditoriums, live music venues, school and community halls, conference centres and nightclubs. A 15 inch woofer and 1.4 inch compression driver on a rotatable 80 x 50 degree horn reach 132.5 dB maximum SPL with response down to 48 Hz.
Sensitivity is a high 99.4 dB, so you get plenty of level for each watt. Run it passive on one amplifier channel or bi-amp it from a Quest QX or QXD amplifier. The marine plywood cabinet has a polyurea coating and steel mesh grille, and it mounts with the HBRQi15 horizontal or VBRQi15 vertical bracket. Available in black or white.

Forefront Tip
At 34.5 kg the Qi15 needs a solid fixing and a two person lift, so plan the bracket position against structure early in the job. In big rooms, add a Qi18S subwoofer and drive the system from a Quest QXD amplifier so the speaker presets and limiters are set from day one.
