Klipsch R-12 SW Overview

With its founder, Paul Klipsch being a renowned pioneer in the audio industry, these speakers have paved the way to changing how we listen to music forever!

What’s great about these speakers is that there’s no break-in period; it sounded great from the first minute!

Plus, they’re aesthetically pleasing too!

The Klipsch R-12SW subwoofer is a 10″ or 12″ subwoofer with 200W or 400W of dynamic power from an all-digital amplifier.

Its design includes a built-in digital crossover and phase control that can deliver OUTSTANDING performance for both music and movies.

Main Features

Check out the features of the Klipsch R-12SW subwoofer you are sure to love:


The Klipsch R-12SW build quality is solid and neat. It is designed with utmost class and luxury, looking above par for its price tag.

The cabinet of this subwoofer is made with standard medium density fiber wood brushed with black polymer veneer. This brushed veneer gives it its texture for a higher-end feel.

Rubber surrounds the cabinet of the driver for added security and durability.

The Klipsch R-12SW carries a less flexible copper diaphragm. This minimizes distortion, especially at lower frequencies.

  • Copper is more durable compared to other flexible materials like paper and plastic, which most speakers are made of. It also gives it that minimalistic feel that can fit any home theater setup.

On the front of the subwoofer, you will find a removable cloth grille with minimal curves on its edges that give it its sleek look.

This also covers its LED indicator, softening the glowing light when in a dark room.

On its back panel, you will find its controls, power cord, and rear-firing port, and on the bottom are four thick rubber feet for sound absorption and to reduce floor vibrations.

Dynamic Power

You can opt for the 10″ or 12″ subwoofer with 200W and 400W dynamic power.

With this power, your speaker can create deep and clear sounds that enhance your whole listening experience!

RCA Audio Inputs

The Klipsch R-12SW comes with a set of RCA audio inputs. 

The left input also functions as the LFE input for better audio frequency response. These give the ability to reach low frequencies from 29Hz to 120Hz without distortion.

Knobs and Switches

The back panel contains knobs and switches that include an on/auto/off switch, a phase switch, a gain knob, and an adjustable low-pass filter.

The gain knob adjusts the volume of the audio signal over to the speakers connected to the receiver.

If you want the bass to stand out, increase the gain on the subwoofer.

The low pass crossover and phase switch adds electrical delay to the audio signal for a balanced frequency and level of bass.

For multiple speakers, this must be set to 180 degrees to improve the frequency response between opposite-facing speakers.

Lastly, a low-pass filter knob is also available to increase the cut-off of frequencies from the upper range of 120Hz down to 40Hz. 


The Klipsch R-12SW has a built-in digital amplifier that creates enough power allowing listeners to enjoy clear and solid sounds.

Sound Quality and Bass

Unlike other subwoofers in its price range, this copper spun woofer does not create that rumbling noise that comes when low frequencies are played at a high volume.

Distortions are at a minimum too!

Even the deepest bass notes can be heard accurately, clearly, and smoothly, thanks to the copper diaphragm of the Klipsch R-12SW sub-woofer.

However, many people have noticed hearing an occasional hum. That’s because of a ground loop feedback that occurs when multiple devices are plugged into separate outlets.

If this is an issue, it is advised to purchase better quality audio cables than what the kit comes with.


Unlike other subwoofers in the same price range, the Klipsch R-12SW does not come with a wireless connection. Quite surprising in this day and age, isn’t it?

It does, however, include a WA-2 port that connects the wireless kit to achieve connectivity, which can be bought separately.

Alternatives to Consider

If you want to broaden your options a little bit, here are 3 alternatives you can consider that are on par with the Klipsch R-12SW.

SVS SB-1000 Pro Subwoofer

This consumer-level sub can still pack a punch at very low frequencies!

It has a wide frequency range from 20-270Hz that provides enough bass for your exciting movie nights.

The SB-1000 Pro is also accompanied by a smartphone app so you can control features, adjust volumes, create presets, and optimize settings in the comforts of your coach.

This mid-range subwoofer is a neat 12″ driver that is easy to tuck under furniture. It is PERFECT for a small home theater.

PreSonus Temblor T10

This studio-grade sub is feature-packed to suit any home theater or music studio.

This 250W powered subwoofer, cased in black non-resonant MDF, is a 10″ front-firing woofer that can deliver superior quality bass sounds even at higher outputs.

It includes rubber feet, a footswitch connector, and a footswitch.

Other notable features include a high pass filter and a continuous variable low pass filter that integrate well with your home theater.

KEF KC62 Subwoofer

This side-firing design compact subwoofer is a sleek and simple box you can easily tuck out of sight.

But don’t be fooled by its size!

It comes with two 6.5 in drivers and a 1000W built-in amplification that can deliver big and deep bass sounds for all bass lovers.

It’s a great-looking speaker with a lot of power but is not the most affordable option.

Frequently Asked Questions

Does Klipsch R-12SW Have Bluetooth?

Unfortunately, unlike other speakers, the Klipsch R-12SW does not have Bluetooth capabilities on its own.

The subwoofer will have to be connected to a standard RCA cable into an output on the receiver to function.

What Should My Klipsch Subwoofer Be Set to?

It would be good to turn the low-pass filter knob entirely to the right to set the subwoofer on LFE mode.

This will send only those deep and rumbling frequencies to your music system so every sound comes out crisp and balanced.

Putting too much bass in one speaker will create fuzzy noises.

Also, if you are connecting multiple speakers for surround sound purposes, put one phase control at 0 degrees and the other at 180 degrees when the speakers are facing each other.

This is so that they don’t cancel out each other’s frequencies.

How Do I Connect My Wireless Klipsch Subwoofer to My Receiver?

The downside to this subwoofer for your sound system is that it does not feature any wireless connectivity.

If you still prefer the Klipsch R 12SW for its other features but wish to benefit from the convenience of wireless connectivity, you can buy the R 12SW kit that connects to a WA-2 port on its back panel to connect to the speaker through Bluetooth.
