INTRODUCTION
Thank you for purchasing a Sonance Landscape Series
Subwoofer. When properly installed, this subwoofer will
provide you with years of outdoor entertainment. To get
the most out of your new subwoofer, please read this
manual thoroughly before you begin installation.
IMPORTANT: Read this section in its entirety before
attempting use of subwoofer.
IMPORTANT SAFETY INSTRUCTIONS
Always follow these basic safety precautions when using
your subwoofer to reduce the risk of fire, electric shock,
and injury to prople or objects.
1. Read all the safety and operating instructions before
operating the subwoofer and retain them for future
reference.
2. Adhere to all warnings and precautions listed on the
subwoofer and in the operating instructions.
3. Follow all operating instructions.
SUBWOOFER PLACEMENT
The SLS system is designed to deliver a seamless, evenly
dispersed sound field in an ‘open air’ environment. An
array of multiple satellite speakers and subwoofers should
be strategically placed to minimize ‘hot spots’ and ‘nulls’
as you move around the outdoor entertainment area.
As a general guideline, one subwoofer will cover about
2,000 square feet of listening area.
INSTALLATION
1. Select a central location for the subwoofer if using
only one (see Figure 1). If using multiple subwoofers,
select locations that are the same distance from the
main listening area. Sonance recommends one SLS
sub installed after every four to five sats in a chain.

ADJUSTABLE TAP
SLS features a wide bandwidth Sonance Laminated Core
Transformer (SLCT) with an adjustable tap, allowing the
system to be configured for 70V/100V or 8 ohm. If using
this SLS product in an 8 ohm application, ensure the
tap switch is positioned to the 8 ohm setting. If using
this product in a 70V/100V system, ensure the tap is
positioned to one of the 70V/100V settings.
NOTE: Ensure that all satellites and subwoofers are set
to either 70V/100V or 8 ohm tap settings to avoid any
damage to your amplifier. DO NOT combine products
set to any of the 70V/100V settings with products set
to the 8 ohm setting on a single amplifier.
Some 70V/100V system designs will require variations
of higher and lower output in dierent areas of the
landscaping. The SLCT adjustable tap allows each
satellite or subwoofer to be individually dialed to the
desired output. Adjusting the tap settings will impact
your wattage calculations. Please review the Wattage
Calculator on the Sonance website for more information:

NOTE: This product ships with the SLCT adjustable
tap set to 300W. Adjustments can be made to the
tap switch once all the satellites and subwoofers are
connected to achieve the appropriate output level.

PLANNING
The maximum number of satellites and subwoofers that
can be used in a system will depend on the amplifier
power. It is important to calculate the amplifier power
your installation will require before you begin. Multiple
amplifiers may be required in large installations. Refer to
the SLS wattage calculator on the Sonance website:
sonance.com/collections/sonance-landscape-series
SUBWOOFER INSTALLATION
SLS systems allow for speakers to be daisy chained
together. In a typical system with one zone of audio,
run a stereo or 4-conductor speaker wire from the amp
to the closest speaker. Designate the first speaker as
either left or right and connect the appropriate positive
and negative wires to the speaker terminals. Continue
alternating the wires between the left and right channels
for each speaker, creating a daisy chain of stereo
satellites. The sub can be wired anywhere in the chain
and will receive either left or right speaker wires (see
Figure 3).
1. Find the best location to complement your other
speakers.
2. Decide which channel the subwoofer will go on,
calculate load. See wattage calculator.
3. Connect to amplifier wiring using the supplied wire
nuts (see Figure 2).

Note: We recommend using 14/4 direct burial wire for
distances up to 200’ and 12/4 direct burial for longer
runs. Keep wires as short as possible to minimize resistive
wire losses.
Caution: The amp should not be connected to AC power
until all speaker wire connections are completed. High
power 70 volt amps present a serious shock hazard.
4. Dig a 4–5” deep trench for running the speaker wires.
5. Run the wire through the trench from the amplifier to
the first speaker location.
6. Connect the direct burial wire to each speaker wire;
connections should be made with either silicone filled
wire connectors or appropriate junction boxes (see
Figure 2).
IMPORTANT: Be sure not to let any stray ‘+’ and ‘–’
strands touch each other. Touching strands can cause
a short-circuit that could damage your amplifier and
degrade sound quality.
7. After all the speakers connections are completed,
connect the wires to your amp (see Figure 3).
8. Turn your amplifier on and test the system with your
favorite music. If the speakers are operating properly,
refill the wire trench and enjoy your new system.
