Overview
This system includes two Quest Qi15 15 inch two way speakers as your left and right mains, plus 2 or 4 Qi18S 18 inch subwoofers, Quest QXD DSP amplification, two VBRQi15 vertical brackets, and the speaker cable and speakON connectors to wire it all up. The Qi15s hang from the ceiling above the stage on the VBRQi15 brackets, angled down at the audience, and the Qi18S subs sit on the floor. Choose 2 subs on a single QXD-10K, or 4 subs with a QXD-10K for the subs and a bridged QXD-5K for the two Qi15s.
Shipping: Shipping for this large item will be quoted and is not included in the price.
It suits churches, school halls, function venues and clubs of around 100 to 400 people. The Qi15's rotatable 80 x 50 degree horn spreads sound evenly across a wide seating area, and every box gets its own amplifier channel. Crossover, EQ and limiting all live in the QXD's DSP, so the system is set up once and stays protected from week to week, whoever is on the desk.
Configurations
- 2x Qi15 + 2x Qi18S, QXD-10K: one amplifier runs all four boxes, one per channel. Ideal for speech, playback and acoustic worship.
- 2x Qi15 + 4x Qi18S, QXD-10K + QXD-5K: twice the subs for more low end headroom, for live bands and contemporary worship. The QXD-10K drives one sub per channel and a bridged QXD-5K drives the two Qi15s.

Forefront Tip
The two Qi15s come with VBRQi15 vertical brackets to hang them upright from the ceiling above the stage. Where headroom is tight, or you want the mains on their side, we can swap to HBRQi15 horizontal brackets at the same price; Quest lists the HBRQi15 for wall or ceiling mounting. Either way, fix into structure and fit a rated secondary safety. The kit allows a 20 m run to each main and 10 m to each sub, so tell us your actual cable run lengths when you order or ask for a quote, and we will cut the cable to suit.
