WARNING

Turn that down and listen!

If you expose your hearing to the loud decibel levels this product is capable of producing, you may experience permanent hearing loss. When you play this product at its loudest, you play at your own risk.

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 usually 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 listening 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 Subwoofores 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 subwooers 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 [e-mail]. 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 subwooers—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, minimize 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 automotive environments.
• Hex-key terminals for clean, professional hookups can accommodate up to 8 gauge speaker wire.

INSTALLATION

NOTES:

SR Subwoofoers are heavy:

The SR104/SR104DVC

weighs 24.5 lb. (11.1kg).

The SR124/SR124DVC

weighs 26.5 lb. (12.0kg).

To adequately support the subwoofer in its enclosure, use 3/4'' (19mm) to

1" (25.4mm) MDF for the front baffle.

If you intend to mount your SR Subwoofer with the magnet facing out, ensure that the pilot holes are small and that you use mounting screws with an aggressive thread that will seat the subwoofer securely in the baffle.

For complete details on building an enclosure for your SR Subwoofer, go to: polkaudio.com/car/toolbox/subboxplans/.

2 Ohm Wiring

Two 4 Ohm subwoofoers wired in parallel will present a 2 Ohm load. Make sure that your amplifier is 2 Ohm stable when configured in the bridge mode. Consult your amplifier's owner's manual before wiring in this configuration.

NOTE: In order to make it easy to parallel multiple subwoofoers, the two positive terminals are connected together. The same has been done with the negative terminals.
