General Description

The QM350i is a passive two way bass 
reflex design speaker suitable for mobile or 
installation use. The design characteristics of 
the QM350i make it suitable for both full range 
use or as the high-mid component of a multi 
way system with sub-bass enhancement. 

The new generation neodymium high 
frequency transducer is matched to a 
rotatable asymmetrical wave guide that can 
be rotated through 270 degrees for horizontal, 
vertical or fold-back monitor installation.

The asymmetrical coverage allows the horn 
to achieve both long throw performance 
and wide angle close coverage without 
“hot zones” or adding to unnecessary room 
reflections that can degrade vocal intelligibil-
ity. The unit can be used in a stand alone 
configuration or as part of a system coupled 
with any Quest sub-bass system. When used 
in conjunction with these devices, the QM350i 
will form part of a high performance  multi 
way audio system.

Installation

Temporary installation is possible with the 
35mm floor stand mounting in the base of 
the enclosure. Fold-back installation can give 
extra uniform stage performance by rotating 
the horn flare to the “fold-back” position. 

Five M 8 thread inserts are located on the top, 
sides and one under the QM350i enclosure. 

These are intended to be used with the 
WB350i wall bracket. 

QM Range Flying Accessories 

Two rigging accessories are available for the 
QM350i:

WB 350i  Wall bracket kit

QB450 Protective transit cover

Functional Design

The QM350i features an asymmetrical 
horizontal angle along one side which makes 
it suitable for use as a stage\foldback wedge 
when laid flat. The QM350i can be easily 
maneuvered across a stage or down a loading 
ramp by one person.

Solid Build Construction

The QM350i is well suited to all professional 
applications. The synthetic casing is specially 
formulated to withstand demanding use 
and the heavy gauge power-coated steel 
grill ensures the driver and horn are always 
protected. 

WARNING

Flying the box from one insert must not be attempted! Improper 

installation may result in damage, injury or death.
