ALL-ENVIRONMENT IN-GROUND,
OUTDOOR SUBWOOFER
featuring Dual 12-inch Metal Alloy Woofers
Thank you for your purchase of the NEAR IGS212 subwoofer! This guide will assist
in the proper installation of your subwoofer. When you couple the IGS212 with the
NEAR XL-Series amplifiers, you are ensured the highest level of bass performance.
By taking a few moments to review this setup guide, you ensure that your new system
will quickly deliver audiophile-quality musical reproduction. The IGS212 is a sealed
bandpass, outdoor subwoofer that provides exceptionally high-impact natural sound
and can withstand nearly all types of environment and weather conditions. The
subwoofer combines two industry-leading technologies from NEAR: Metal Diaphragm
Technology (MDT), which ensures speaker cone stability in all-environmental conditions,
and Magnetic Liquid Suspension (MLS), a Ferrofluid seal around the magnet gap
and voice coil that provides protection from moisture and corrosion as well as
near-perfect voice coil alignment. Incidentally, the in-ground bandpass subwoofer
design was originally patented by NEAR.
Placement and Sound Quality
Dispersion of the IGS212 is a full 360 degrees! This means that the orientation of the
subwoofer is not critical. We recommend that you install the subwoofer in-ground.
The packed earth around the enclosure suppresses enclosure resonance for improved
low-frequency definition. The IGS212’s enclosure features drainage channels to drain
water that may enter the enclosure via the bass vents.

Speaker cables from the amplifier to the
subwoofer may be directly buried provided
you use direct burial-rated stranded speaker
cable. We highly recommend the use of a
1” to 1-1/2” ID conduit to protect the wires
from degradation and damage due to excavation or normal gardening activities. The
NEAR IGS212 subwoofer has entry and exit
wire/conduit channels on the bottom of the
enclosure. We highly recommend the use
of the NEAR IE1 junction box.

In-ground Mounting/Burial
When preparing an IGS212 subwoofer for burial, select an area that allows the depth
needed for the enclosure plus 6-inches to allow for a layer of crushed stone or gravel

STONE
When preparing an IGS212 subwoofer for burial, select an area that allows the depth
needed for the enclosure plus 6-inches to allow for a layer of crushed stone or gravel.
In most cases, the hole should be dug to a level of 18-24 inches. The lower edge of the
3 Output Vents (A) should be 2-3 inches (50-70mm) above ground level as illustrated
above. A layer of mulch or loose stone may be added up to the lower edge of the vents
as long as it allows water to flow through. Although the enclosure has channels for
draining water that may enter the enclosure through the vents, it is best to prevent
water from entering the enclosure in the first place. If the subwoofer is in a location
where water may flow around it during heavy rains, raise the subwoofer another
2-3 inches (50-75mm) above ground level. Place a layer of permeable landscape
fabric between the crushed drainage stone and the subwoofer.
WARNING: Customer is responsible for the wiring materials to/from amplifier and
to/from other speakers/subwoofers as well as the selection of the installation area.
It is recommended that a professional be consulted when connecting speakers if
the installer does not have sufficient knowledge in working with electrical components.

In-ground Install Angles
of an IGS212 Subwoofer
A
LEVEL: INSTALL 1 SLOPE: INSTALL 2
The IGS212 subwoofer is designed with a slightly angled driver so that when the
enclosure is on a level plane (see Install 1 & 2), any moisture will be channeled away
from the woofer. DO NOT install the subwoofer at an angle as pictured in Install 3.
