Definitive Technology LS-400 satellite speakers, AW Series under-eave outdoor speakers, BL Series bollard speakers or
combined with other custom outdoor speaker systems.
1. Introduction
3. Planning the Installation
• To achieve the best coverage, place the subwoofer
approximately . 5–6' away from the adjacent speakers
Refer to the instructions for your particular speakers to
see what the manufacturer recommends for speaker
distance.
• Place the subwoofer as close to the center of the
speakers as possible for optimal frequency balance
between the subwoofer and speakers.
• For applications that require more bass, place the
subwoofer near an acoustically reflective surface, such
as a wall or barrier, to reinforce the low frequencies.
• In some applications, better performance may be
achieved by placing the subwoofer closer to the
primary listening position or by adding a second LS-80
or LS-100 subwoofer. If two subwoofers are used,
select locations that are the same distance from the
main listening area, and place one LS-80 or LS-100
subwoofer after every 3–4 speakers in the chain.
• If possible, try placing the speakers and subwoofer
in locations that minimize volume peaks and nulls
throughout the outdoor listening area.
• To avoid potential damage from landscapers, be
mindful of where you mount the subwoofer and
speakers. Locate the subwoofer in an area that will not
flood with standing water.
NOTE: One LS-80 subwoofer will cover a listening area of
about 1500 square feet; one LS-100 will cover a listening area
of about 2000 square feet.
