Direct Burial Installation
Dig a hole 12” in diameter and 14” deep. Level the
speaker in the hole then backll with clean sand or soil
being sure that the grill drain hole remains at least 1”
above grade. Compact the sand/soil to make sure the
speaker will not shift or settle over time.
Note: Hard to dig areas may benet from a gas-powered
handheld 12” auger (may be rented locally).
Note: Avoid installing in locations that are prone to
ooding.
Hardscape Mount Installation
Once the appropriate location is selected, secure the
recess mount to the surface with fasteners appropriate
for the surface material. Slide the bollard over the recess
mount and orient the speaker in the appropriate direction.
Insert the supplied set screws and tighten in a uniform
fashion so they all make contact with the recess mount
before nal tightening.
WIRING INSTALLATION
All Coastal Source speakers feature our patented Coastal
Connector™ for a waterproof direct burial connection.
For connecting to a Coastal Source amplier just select
the appropriate cable lengths and y-cables and Plug+Play
the speakers to the amplier. For connection to 3rd
party (non-CS) ampliers, Coastal Source pigtail cables
are available to convert the Coastal Connector™ on the
speaker to a typical 2 conductor bare wire that can be
spliced in to a conventionally wired system.
Cabling Rules
Coastal Connector™ 12AWG cables can be run up to
300’ total per channel without any signicant degradation
of performance. Coastal Source systems ship preset for
typical applications. Adjustments should only by made my
Certied Dealers.
Coastal Source speakers operate at 8 ohms. When using
Coastal Source ampliers (check amp specications for
details) up to (4) 10.0 Ellipse Bollard Subwoofers may be
daisy chained by using a Parallel Audio Y-Divider at each
subwoofer
Two speakers can be paralleled per channel with amps
that are stable to 4 ohms and four can be paralleled per
channel with amps that are stable to 2 ohms. Carefully
consult the amplier manual for low impedance drive
ability and stability. All Coastal Source ampliers are stable
to 2 ohms.
SOUND TUNING
Note that optimal sound tuning is subjective and
specic to each listener so there are no hard and fast
rules for optimizing the sound of a Coastal Source system.
We have designed with exibility to allow you to shape
the sound to your personal preferences. The following
information is offered as a brief guide. It is highly
recommended to take the time to experiment and tune
the system to achieve your desired sound.
SUBWOOFER PLACEMENT
Above Ground - Open area
Less bass response.
Above Ground - Near a rear wall surface
Heavy bass response. Low frequencies gather in corners
and travel better though surfaces like the ground or walls
than the air.
Buried Vertical
Slightly heavier bass response than above ground.
Buried at 45° Angle - Speaker grill
perpendicular to the ground surface
Heaviest bass response. The driver being close to the
ground allows for those low frequencies to travel through
and be reected by the ground.
Subwoofers
Since very low frequencies are omni-directional placement
is less critical, but experimenting with placement is still
recommended since proximity to walls and corners will
have a signicant effect on the bass output.
Streaming Quality
Today most people stream music from a mobile device
to listen to music. This makes the quality of the streaming
source paramount to the overall quality of the sound of
an audio system. Whether demoing a system for a client,
showing off to your friends, or just listening by yourself,
streaming quality can make a huge difference. Below are
the maximum streaming quality rates available for the most
