Design and Build

The Klipsch R-12SW subwoofer has a cube-like shape like most subwoofers. A little more than 30 pounds weigh the unit, with dimensions of 14 x 18.5 x 16 inches. It has a luxurious, but bulky design.

Klipsch subwoofers are bulky and difficult to reposition because of their size. They are well-built and sturdy.

In terms of build quality, the Klipsch R-12SW is outstanding for its price point. This same subwoofer has a smaller footprint than a subwoofer with a similar power rating.

• A black polymer veneer covers the medium density fiberboard (MDF) cabinet. There is a little more texture with the brushed veneer than the flat black.
• Subwoofers are covered with fabric grilles. It can reach the corners of the front panel despite having a minimal curve around the edges. LED indicators are also covered, which makes them less visible in a dark room.
• Klipsch R-12SW features a 12-inch driver as well as a 400W all-digital amplifier. Copper diaphragm accentuates the design of the driver.
• Speakers are usually made of plastic or paper. Especially at low frequencies, copper is less flexible and therefore minimizes distortion. Copper is a more durable material than other materials.
• Rubber rings secure Klipsch speakers to their cabinets. Rubber surrounds may last much longer than foam and are more durable than foam.

Located on the back panel are a power cord, a port for rear-firing, and control buttons. The subwoofer is equipped with thick rubber feet to minimize vibration and sound absorption.

Features and Connectivity

There are RCA audio inputs on the Klipsch R-12SW. LFE inputs (low-frequency effects) are also taken from the left input.

Also on the back panel are a number of knobs and switches, including the on/auto/off switch, the phase switch, a gain control, and an adjustable low-pass filter.

• A knob on the receiver controls the volume going out to the speakers. The speakers will produce the same amount of audio in the same volume if you set the gain to 0. In order to make the subwoofer stand out more, you can increase the gain.
• An electrical delay is added to the audio signal by using a phase switch. The subwoofer’s polarity can be reversed by 180-degrees to improve the frequency response when it is set opposite the other speakers.
• You can adjust the low-pass filter knob to adjust the cutoff frequency for the low bass that passes through the subwoofer. There is a 29Hz to 120Hz frequency response on the Klipsch R-12SW. You can adjust the low-pass filter’s cutoff frequency between 120Hz and 40Hz.
• In low-pass filter mode, the subwoofer will be completely turned to the right. Dedicated subwoofer outputs of amplifiers and receivers connect subwoofers via LFE. Rather than sending the entire audio signal to the subwoofer, it can send only the low frequencies, which results in greater clarity.

Other subwoofers in the same price range may not offer as many features as the Klipsch R-12SW. Wireless options may also be available, along with detachable power cables.

In spite of the lack of extra features, the audio quality is not affected.

Klipsch offers wireless kits if you need wireless connectivity. Connect the wireless kit to the WA-2 port on the back panel to add wireless capability.

• The Klipsch R-12SW is also an excellent speaker. All-digital amplifiers provide 200W RMS and 400W dynamic power to this 12-inch subwoofer. It will provide a lot of bass to your home audio system.

As a result of ground loop feedback, customers often hear a hum.

Multiple devices are plugged into one outlet at the same time, which causes this. If you are using inexpensive audio cables, such as Klipsch’s R-12SW cable, you may hear hums. Use the shortest possible cable length if you hear hums.

How many watts does the Klipsch R 12SW subwoofer have?

Front-firing 12-inch copper-spun woofer. 400 watts of dynamic power from all-digital amplifiers. Excellent for movies and music. High pass and low pass crossovers.

Which Klipsch subwoofers are the best?

Klipsch subwoofers like this one are our audiophiles’ favorites. Additionally, the brand’s copper-spun IMG woofer is paired with RCA and line-level inputs for maximum compatibility with your receiver.

Subwoofers from Klipsch can be placed on their sides, right?

Subwoofers that fire down cannot be placed on their sides. They use the floor to amplify the bass. When oriented on their side, their sound will be amplified more through the air.
