Just a little humor there, but true nonetheless. For over 15 years we here at SWR have been putting everything we know about bass into our
Professional Series and Custom Pro Specialist Series bass cabinets. We've earned a reputation for designing and manufacturing gear that has
changed the way bassists hear themselves. That's why you'll find our bass amps, cabinets, and combos on stages and in recording studios all over the
world, and why you'll hear SWR on countless recordings, spanning all genres of music.
Inside this Owner's Manual you'll find specifications, features, and usage suggestions for every Professional Series and Custom Pro Specialist Series
bass enclosure we make. New SWR user and seasoned user alike will benefit from reading through this brief but informative manual. You can learn all
about your current cabinet AND check out your SWR extension options, too.
Thanks for making SWR a part of your bass amplification system.
Sincerely,

GENERAL INFORMATION
CONNECTION
Only one amplifier at a time can be connected to your SWR speaker enclosure. DO NOT plug two amplifiers into one speaker enclosure, as it will not
work and may damage your system. Always complete your amplifier-to-speaker and speaker-to-speaker connections before powering up your system.
SPEAKER CABLE
Only SPEAKER CABLE of 18 gauge or heavier (the heavier the cable, the lower the gauge) should be used to connect your amplifier to your SWR speaker
enclosure. Do not use shielded instrument cable to connect your amplifier to your speakers, as this can result in intermittent power loss, cause your amp to
oscillate and damage itself and/or your speakers, and render the cable useless for any purpose.
SPEAKON JACKS
Whenever possible, use of the Speakon jacks is recommended. Speakon jacks and connectors offer the best possible connection and are far superi-
or to banana or 1/4" phone jacks in that they not only lock in place (preventing accidental disconnection), but also offer a greater and more stable con-
nection surface. This solid connection provides a more effective transfer of power to your speakers, particularly from high-powered amplifiers.
TWEETER PROTECTION CIRCUIT
The tweeter protection circuit for SWR Professional Series speaker enclosures includes a size 3AG, 3 amp, 250 volt, fast-blo fuse. Do not replace this
with a fuse of a higher rating as it will void your warranty. A sudden burst of feedback or a heavily clipped waveform can cause the fuse to open, result-
ing in loss of output from the tweeter.
SHOCK MOUNTED STEEL GRILL
The custom-manufactured steel grill is mounted on the top and sides with hard rubber standoffs and is installed to protect your SWR speaker enclo-
sure's components from puncture or other physical damage. The standoffs act as "shock absorbers" when the grill is bumped, and are also intended to
prevent the grill from rattling during use. Prior to shipping, the grill mounting screws are tightened to a point where the standoff barely compresses.
This keeps the height of the grill far enough off the speaker and prevents the grill from rattling on the head of the screw. Should the screws loosen,
some rattling may occur. If this happens, simply tighten the screws until they become snug. Do not over-tighten the screws, as this could bring the grill
too close to your speaker(s) and cause interference with the speaker cone.
CLEANING AND MAINTENANCE
A soft, dry cloth can be used to remove smudges or fingerprints from the chrome grill. A stiff brush (such as those available in the cleaning section of
most supermarkets) can be used to keep the cabinet's carpeting free of lint, pet hair and dust. Should you encounter a problem with the carpet collect-
ing odor (from smokey clubs, etc.) a common carpet cleaner can be used. It is recommended that, prior to spraying down the entire covering, you test
whichever cleaner you choose on a small, inconspicuous area on the underside of the enclosure. This will prevent any accidental discoloration from
being in view. All screws on the baffle and input panel should be checked periodically for tightness, so as not to become loose (causing rattles or air
leaks) or lost.
