SAFE LIMITS
OF OPERATION
Damage to loudspeakers can occur when an
amplifier, regardless of its wattage, is made
to play at higher listening levels than it can
produce at low distortion levels. This is usu-
ally beyond the "noon or 1 o'clock" position
on the volume control. Operation at this
level can result in very high levels of audible
distortion originating in the amplifier, which
can add a harsh, gritty sound to your listen-
ing material. Contrary to popular belief,
a speaker is more likely to be damaged by
trying to get too much volume from a low-
powered amplifier or receiver than from a
high-powered one.
PRE-CONDITIONING
SR Subwoofers require a pre-conditioning
period because the suspension (spiders and
surround) is stiff when brand new. We
recommend playing your SR Subwoofer
at moderate listening levels for anywhere
from 40 to 60 hours before you really crank
up the volume. A pre-conditioning period
helps loosen the suspension for better
transient response and lower bass
frequency extension.
TAKE INVENTORY
Inside your subwoofers carton,
you should find:
1 SR Subwoofer & Gasket
1 SR Subwoofer Manual
1 Online Registration Card
1 2.5mm Allen Key
Please inspect your subwoofer(s) carefully.
Notify your Polk Audio dealer if you notice
any damage or missing items. Polk Audio's
Customer Service Department is available
from 9am–6pm, EST, Monday through Friday,
at 800-377-7655 (US & Canada only, outside
the US call 410-358-3600) or via email at
polkcs@polkaudio.com. Keep the carton and
packing material; this will do the best job
of protecting your subwoofer(s) if it has to
be shipped.
GENERAL
DESCRIPTION
The same engineering excellence and
performance obsession that went into the
SR6500 system has been applied to four
new subwoofers—the SR124, SR124DVC,
SR104 and SR104DVC. These models are
designed to provide competition-grade bass
performance when installed in small sealed
enclosures (.88 cubic foot for the SR124 and
.66 cubic foot for the SR104).
FEATURES
• Available in both Single and Dual 4 Ohm
Voice Coil configurations.
• A 2.5 inch glass/epoxy voice coil former
wound with four layers of heavy gauge
high temperature Aluminum wire provides
the highest power handling (700 Watts
Continuous!) and reliability in Polk
Audio's history.
• Voice coil is bathed in cooling air via an
extensive network of vents in the pole
piece and basket.
• Specially designed curved vanes smooth
the airflow to prevent any air turbulence
that could cause noise and "chuffing."
• Dual spiders tightly control the cone's
long excursion for the ultimate in "tight,"
detailed and musical bass.
• Polk's Klippel Distortion Analyzer, which
uses laser technology to measure and
optimize driver behavior under high
output, helps maximize linearity, mini-
mize distortion, flatten and extend
frequency response.
• Spider collar, sandwiched between the
dual spiders, ensures precise alignment
of the voice coil. The collar also reduces
stress on the suspension for increased
durability.
• ABS Cone employs catenary geometry, a
naturally strong and stable geometry for
ultra-low distortion bass.
• Massive die-cast aluminum basket.
• NBR (Nitrile Butyl Rubber) Surround
damps distortion-inducing resonance
as it stands up to harsh auto-
motive environments.
• Hex-key terminals for clean, professional
hookups can accommodate up to 8 gauge
speaker wire.
