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

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.

Connections and Operation 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 counterclockwise 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.

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 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 par ticular 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.
