The Perfect Production Partner

QM350i High Power 12" Loudspeaker

The QM350i is a multipurpose passive speaker system designed and built for professional mobile live sound applications and permanent audio installations. Featuring a 12" + 1" and asymmetrical wave-guide, the QM350i boasts power handling of 350 watts RMS (700w music power). This makes the QM350i the perfect mid powered versatile and hi-fidelity point source front of house speaker or fold-back monitor for professional applications.

In Venue or On Road

Voice projection in venues with challenging acoustics is where the QM350i shines. This feature makes the QM350i a great choice for A/V and live sound production, particularly when highly intelligible voice reproduction is required. The high powered components and build construction will stand up to everything a rental department or permanent installation can throw at it. From the onset of a single event, an audio professional will begin to see how the QM350i has been designed and built by engineers with a long history of live production. The heavy gauge steel grill and recessed connectors coupled with the ergonomic casing design, make the QM350i a no compromise pro performer in the hands of any professional needing instant results.

Wave Guided HF

The QM350i boasts an exceptionally accurate HF response due to its purpose designed high frequency driver which is coupled to Quest's custom designed asymmetrical wave-guide delivering ultra smooth frequency response. In addition, the wave-guide can be rotated through four dispersion plains maximizing the QM 350i's application potential.

The 1" horn sports a wide 90-100 degree coverage at the base of the flare and a long throw 40 degrees at the top. This ensures that the HF energy can be directed accurately wherever it is needed without exciting unnecessary room reverberation. This unique horn geometry design also minimizes "hot zones”. This is a great benefit for sound guys when microphones are positioned closely to speaker systems and is a great benefit for a monitor engineer (when the horn flare is rotated into horizontal monitor mode).

Sound Rigging

Permanent installation or temporary rigging to mobile stage truss can be achieved with the WB350 "U" wall bracket. When installing the WB350 bracket in horizontal installation the QM350i is the ideal speaker system for coverage in venues with low ceilings, thanks to the long throw asymmetrical horn. A 35mm speaker stand pole fitting is located on the base of the casing.

Wooden Body, Steel Faced

The QM350i chassis is made of the same heavy duty birch ply wood as our high performance and industry trusted HPI systems. Finished with an extremely resilient black coating and fitted with a wrap-around heavy gauge protective steel grille, the QM350i has been crafted to endure even the most demanding environments and is built to last.

Power Me Up

The QM350i can take serious power by any standard. Quest Engineering recommends an amplifier capable of delivering 350-500W (8ohm) to ensure full performance. The perfect solution are Quest's QA3004 or the new QX4500.
