USER MANUAL - GRAVO ACTIVE SUBWOOFER
PAGE 2
Description
The Gravo subwoofer series is a range of powerful stand-alone active subwoofers, designed to work
in a 2.1 configuration with two active satellite speakers or an external stereo amplifier and passive
speakers. Using rugged and acoustically superior birch plywood as the cabinet material and a high-
headroom class D amplifier, these subwoofers are both robust in their handling and powerful in their
performance. Adding precision transducers, they offer great sound as an extension in the subbass
frequency range to any portable and installed sound system.
The Gravo series consists of three different models:
SWA-1210: 12” Driver
SWA-1510: 15” Driver
SWA-1810: 18” Driver
Availability of models may very based on territory. The specifications for each model are available at
the end of this user manual.
Setting up
A. Location
When choosing a location for the Gravo subwoofers, keep the following in mind:
During transport or setup, avoid touching the cones of the loudspeakers with any object or with
your hands, as this could cause irreparable damage. Do not remove the protection grille.
Avoid pointing microphones in the direction of the speakers, as this could result in annoying feed-
back which can damage the speaker drivers.
B. Position
Gravo subwoofers are designed for floor standing operation. Make sure that the floor is flat and even
to avoid the speaker to tumble. Avoid resonating floor positions for better sound.
C. Satellite Speaker Placement
The Gravo subwoofers are equipped with a
1-3/8 inch (35mm) stand pole mount, to allow
mounting of a satellite speaker right on top of
the subwoofer by means of a 35mm distance
tube.
Before lifting the speaker onto the tube, be confi-
dent that you can handle the weight safely and
without injury to yourself, others, or damage to
the speaker.
When taking the satellite speaker off the tube,
take caution if the tube gets caught in the sateli-
ite speaker’s stand mount, as it may fall off unex-
pectedly and cause risk of injury or damage.
