Important Safety Instructions
This symbol warns the user of dangerous voltage levels
localized within the enclosure.
This symbol advises the user to read all accompanying
literature for safe operation of the unit.
∆Read, retain, and follow all instructions. Heed all warnings.
∆WARNING: To prevent damage, fire or shock hazard, do not
expose this unit to rain or moisture.
∆This product should be located away from heat sources such as
radiators, heat registers, or other products that produce heat.
∆This product should only be used with a cart or stand that is
recommended by the manufacturer.
∆Do not drip nor splash liquids, nor place liquid filled containers on
the unit.
∆CAUTION: No user serviceable parts inside, refer servicing to
qualified personnel only.
∆SWR®amplifiers and loudspeaker systems are capable of
producing very high sound pressure levels which may cause
temporary or permanent hearing damage. Use care when
setting and adjusting volume levels during use.

Congratulations on your decision to make a WorkingPro™
bass speaker enclosure part of your bass amplification
system. Since 1984, we here at SWR
®
have been putting
everything we know about bass into the SWR
®
product line.
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 around 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 WorkingPro™
bass speaker enclosure we make. New SWR
®
user and
seasoned user alike will benefit from reading through this
brief but informative manual.
Thank you for choosing SWR
®
.
Sincerely,
SWR
IMPORTANT INFORMATION
•ONLY connect one amplifier to your bass speaker
enclosure(s). Two amplifiers WILL NOT work and may
damage your equipment.
•DO NOT connect speakers with a total impedance load
below the minimum rating of your amplifier to prevent
damage to your equipment. See Impedance Guidelines.
•ONLY connect speakers with a total power handling
capacity that is above the power output rating of your
amplifier to prevent damage to your equipment.
•ALWAYS switch your system power OFF before
connecting or disconnecting speakers.
•ONLY use unshielded speaker cable of 18 gauge or
heavier (such as 16 or 14 gauge) for speaker
connections. Shielded instrument cable WILL NOT work
and may damage your equipment.
•SWR®RECOMMENDS removing the casters from the
WorkingPro™ 4X10T during performance so the cabinet
contacts the floor, extending your bass response.
INPUT PANEL
Tweeter Attenuator Control {A}
This level control adjusts the loudness of the tweeter
(high–frequencies). A normal setting for this control is
straight up (twelve o’clock). Turn the dial fully counter-
clockwise to remove the tweeter from the circuit. Turn the
dial clockwise to increase the high frequency content. NOTE:
Any amplifier clipping (distortion) that occurs will always be
accentuated by the tweeter. Turn down the master volume
on your amplifier to reduce the clipping. See Troubleshooting
below if clipping persists.
An internal (passive) crossover divides the signal, sending
frequencies above 5kHz to the tweeter and those below
5kHz to the drivers.
Input and Output Jacks {B & C}
WorkingPro™ Series speaker enclosures feature both
1/4" {B} and Speakon
®
{C} input/output jacks to provide
flexibility in making your speaker connections. Use the
Speakon
®
jacks whenever possible to take advantage of their
superior power transfer efficiency and locking connectors.
All four jacks are full range and wired in parallel.
Multiple Speaker Enclosures {D}
You can connect multiple WorkingPro™ speaker enclosures
to your amplifier within limits (see Impedance Guidelines
below). Connect the first speaker to your amplifier as usual,
then connect the second speaker to an OUTPUT jack on the
first speaker, and so on.
IMPEDANCE GUIDELINES
Use the impedance ratings on your amplifier and speakers to
determine if a particular combination of speakers is
appropriate for your amplifier. NOTE: All SWR
®
bass speaker
enclosures (and most others) are wired in parallel
(NOT series), therefore, these Impedance Guidelines apply
only to parallel speaker connections. The Illustration below
shows the total impedance loads of various combinations of
speakers connected in parallel.

Generally, you will want to
connect your amplifier to
speakers with a total impedance
load equal to the minimum
impedance rating of your
amplifier. Operating below the
minimum impedance rating can
easily overheat the amplifier and
cause damage. Operating above
the minimum impedance rating
will reduce the amplifier’s
maximum power output.
Notice that different
combinations of speakers can
equal the same total impedance
load. If their impedances are the
same, each speaker will receive equal power from your
amplifier. However, if their impedances are not the same,
speakers with the lowest impedances will receive the most
power. For example, if 4Ω, 8Ωand 16Ωspeakers are
connected, the 4Ωspeaker will receive most of the power
and the 16Ωspeaker will receive almost none of the power.
Take this into consideration when calculating power handling
capacities and when positioning your bass speaker
enclosures.
CLEANING AND MAINTENANCE
A soft, dry cloth can be used to remove smudges or
fingerprints from the speaker grill. A stiff brush can be used
to keep the carpeting clean. Should the carpet acquire an
odor (from smokey clubs, etc.) a common carpet cleaner can
be used according to the product directions.
Cabinet Vibration
Periodically check for and tighten loose screws to prevent
any rattles or air leaks. There are screws on the baffle and
input panel as well as the steel grill. Do not over-tighten the
steel grill screws which may compress the rubber standoffs
and cause interference between the grill and the speaker(s).
TROUBLESHOOTING
I hear unwanted distortion... First identify the source:
Temporarily replace each cable, then the amplifier in turn
with a tested substitute. Turn off the tweeter to isolate the
woofer. If you hear no improvement at any point, contact an
authorized SWR/FMIC service center.
Multiple speaker enclosures have a hollow, thin sound...
Test for reversed wiring: Pull the
speaker cable plug from the amplifier.
Each woofer should move out
(towards the grill) when a 9 volt
battery is applied as shown. If not,
temporarily replace each cable in turn with a tested
substitute. If you see no improvement at any point, contact
an authorized SWR/FMIC service center.
