section of the Workingman's 2x10C may occur if speaker enclosures with total impedances less than the minimum loads listed above are connected to the speaker output section. The owner's manual that came with your speaker cabinet should state its total impedance. On SWR speaker enclosures, the total impedance is generally indicated on the speaker's input panel.

So how do you determine the total impedance of two cabinets hooked up to your Workingman's 2x10C? Here's a quick key of the most common setups:

One 8 ohm enclosure (internal) + one 8 ohm enclosure (extension) = 4 ohms total impedance

This is OK. However:

One 8 ohm enclosure (internal) + one 4 ohm enclosure (extension) = 2.6 ohms total impedance

This is NOT OK! The power amp will eventually overheat and fail.

Here's another formula: To figure out the total impedance of two or more cabinets of equal value hooked up in parallel, divide the impedance of one cabinet by the number of cabinets:

Impedance of one cabinet / number of cabinets = total impedance

(For an even more in-depth discussion of impedance and power rating issues, go to the SWR Website at www.swrsound.com, click on "Support", then click on "Technical Articles," then click on "Plug and Play - Setup Tips for Amps and Speakers"-an article by SWR founder Steve Rabe that ran in the August '92 issue of Bass Player Magazine.)

WORKINGMAN'S 2X10C POWER DELIVERY CAPABILITIES (Power Ratings)

After determining how the extension cabinet you wish to use affects the total operating impedance, you need to take into account the power handling capabilities of that speaker cabinet as compared to what the Workingman's 2x10C can deliver at that operating impedance. Those ratings are as follows:

260 Watts @ 8 ohms (internal speaker system only)

400 Watts @ 4 ohms (internal system with one 8 ohm extension cabinet)

So if you use an 8 ohm extension speaker cabinet along with your internal speaker system, it will get up to 200 watts of power (400 watts split in half), and more during transient peaks. Make sure your extension speaker cabinet can handle the power.

There is also the situation known as under powering your speakers. This is caused when the power amp, in the process of trying to drive one or more speaker cabinets, reaches its limit and goes into clipping. That "clipped" waveform (or "square wave") will quickly heat up the voice coils in speakers, and if operating continually while clipping, eventually will burn the voice coils and cause the speakers to fail. Speakers abused in this fashion are easy to detect and generally not covered under a manufacturer's warranty. (Remember, engaging the Limiter will not allow the power amp to clip, so we recommend that you not disengage the Limiter when running at low total impedances in general.)

Also be aware that when running the amp at 4 ohms, you are operating at the maximum capacity of the power amplifier. With extreme settings on the Gain and Master controls and the Limiter circuit disengaged, you may hear audible clipping of the power amp. If so, you have exceeded the maximum capacity of the power amp. POWER AMP CLIPPING CAN CAUSE DAMAGE BOTH TO ITSELF AND YOUR SPEAKER CABINETS. Either re-engage the Limiter (by pushing in on the Limiter control) to help smooth out the peaks, or back off on the Gain and Master controls.

Remember, it's always better to have a little too much power than just barely enough. If you find yourself constantly wanting more power than the Workingman's 2x10C provides, either:

a) tell your bandmates to turn down

 

b) tell the monitor engineer to turn you up

 

c) (better option) take the time to investigate getting an external power amp for the additional speaker

cabinets to supplement

your rig

 

d) (best option) investigate getting a larger rig (perhaps something modular, with a large head and two

speaker cabinets) for

those gigs where more power and volume is needed

2X10C specifications

The SWR Sound 2X10C is a powerful and versatile bass cabinet designed for both studio sessions and live performances. With its compact size and lightweight design, it is an ideal choice for musicians seeking portability without sacrificing sound quality. The cabinet features two 10-inch custom-designed speakers, specifically engineered to deliver a balanced tonal range and impressive low-end response.

One of the standout features of the 2X10C is its high power handling capability, allowing it to handle up to 400 watts RMS. This ensures that even when pushed to its limits, the cabinet maintains clarity and punch, crucial for any live show or recording environment. The cabinet is also equipped with a high-efficiency horn tweeter, which enhances the higher frequencies and provides a sparkling top-end that complements the rich tones produced by the 10-inch woofers.

The cabinet utilizes SWR's proprietary technologies to enhance performance. The "Bass Reflex" design features strategically positioned ports that help to eliminate unwanted air turbulence while maximizing low-frequency response. This design not only promotes deeper bass tones but also allows the cabinet to remain lightweight, making it easier for musicians to transport.

Another key characteristic of the SWR 2X10C is its rugged construction. Built from durable materials, the cabinet is designed to withstand the rigors of both touring and frequent use. Reinforced corners and a heavy-duty grille protect the speakers from potential damage, ensuring the longevity of the cabinet.

For connectivity, the 2X10C comes with dual 1/4-inch input jacks, enabling easy integration with various amplifiers and allowing for daisy-chaining additional cabinets if more sound output is required. The cabinet is compact enough to fit into most environments, making it a versatile option for a range of musical genres.

In summary, the SWR Sound 2X10C combines advanced features, innovative technology, and robust build quality, making it an exceptional choice for bass players looking for a reliable cabinet that delivers impressive sound across various settings. Whether in a rehearsal space, a studio, or on stage, the 2X10C stands out as a top-tier option that meets the demands of modern musicians.
