A big picture is key for great home theater, but our pulse really quickens when the sound kicks in. For that to happen, we need high-definition speakers that match the image quality on our HDTVs. Polk knows. They're experts on the subject. Their RM87/PSW108 surround sound speaker system teams two customer favorites to deliver maximum sonic realism for your home theater, with minimal impact to your wallet.
First, the speakers: the RM87's reputation for big, clear sound from space-friendly satellites is a hallmark of Polk's RM series design. The front speakers feature two woofers set at an angle to one another, which helps them create a large, spacious soundfield with excellent coverage to the sides. The center channel speaker anchors movie dialogue to your TV screen, and includes an adjustable cradle to angle the sound more precisely to your listening position. Four matching satellite speakers surround you with sound, for a more exciting and realistic experience with your favorite movies and video games. Every sleek satellite comes ready for tabletop, stand- or wall-mounting.
Nothing adds to the thrill of home theater quite like bass, and Polk's PSW108 powered subwoofer delivers. It combines a 10” woofer and 50-watt amp to produce solid, satisfying low frequencies. The cabinet is constructed from non-resonant MDF, and is reinforced with internal bracing for superior bass clarity. We like the way this sturdy little sub rounds out the lower end of music and movie soundtracks — and we love its thunderous oomph with on-screen explosions. Simply connect the PSW108 subwoofer to the RM87 speakers to tap into the full 7.1-channel home theater experience.
When Polk and Crutchfield assembled this system, we built in savings, too — it's $180 less than if you purchased the RM87 system and the PSW108 sub separately.
Looking for speakers that'll deliver thrilling, edge-of-your-seat surround sound? Choosing a pre-matched speaker system is one way to ensure seamless home theater performance. These systems are made up of speakers that share the same tonal characteristics that means the sound will stay consistent as it moves from speaker to speaker around your room. Most pre-matched systems come with a subwoofer a must-have for high-impact bass.

Seven Satellite Speakers: The Polk Audio RM87 home theater speaker package adds surround-back speakers to Polk Audio's original RM85 home theater speaker package. This 7-channel speaker package includes two identical wide dispersion array satellites (RM8), four direct radiating satellite speakers (RM7), and a matching center channel speaker (RM8C).
Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.
Center Channel Speaker (RM8C x 1): The RM87 home theater speaker system features one satellite center-channel speaker. The RM87's center channel speaker consists of two 2-1/2" dynamic balance composite cone drivers and a 3/4" silk/polymer composite dome tweeter for full-bodied sound.
Wide Dispersion Array Front Satellites (RM8 x 2): The RM87 home theater speaker system features two front satellite speakers. The RM87's wide dispersion array satellite speakers create a more enveloping, less localizable surround effect because the speakers drivers are mounted on opposing baffles for a broader and larger front-stage sound field and a more immersive and atmospheric surround field. The speaker features two 2-1/2" dynamic balance composite drivers mounted on different sides of the speaker's enclosure and one 3/4" silk/polymer composite dome tweeter for rich, real life imaging.
Direct Radiating Rear Satellites (RM7 x 4): The RM87 home theater speaker system features four rear satellite speakers. The RM87's direct radiating satellite speakers consist of one 2-1/2 dynamic balance composite cone drivers and a 1/2" dynamic balance composite semi-dome tweeter for distortion free and smooth sound.
Enclosure: The RM87 satellite speakers and center channel feature an acoustic suspension, non-resonant composite enclosure with a high-gloss black finish for great looks and natural sound. The three-sided cabinet design minimizes the visual impact on walls and shelves while the integrated baffle and anti-diffraction grille design allows maximum sound dispersion with minimum diffraction for superior imaging and room-filling sound.
Speaker Terminals: The spring clip terminals located on the rear of the direct radiating satellite speakers and center channel and on the bottom of the array satellite speakers will accept pin connectors and bare wire.
Video Shielded: The RM87 satellite speakers and center channel are magnetically (or video) shielded for safe placement near your TV or computer monitor without causing picture interference.
Mounting Options: The Polk Audio RM87 home theater speaker system offers various mounting options for each speaker.
Note: The RM87's front and rear satellite speakers are compatible with Polk's SA-3 floor speaker-stands (107SA3B, sold separately).
10" Klippel Optimized Woofer: The Polk Audio PSW108 uses a front-firing 10" composite polymer cone driver (with foam surround) for deep, accurate response with low distortion. By using a state-of-the-art Klippel Distortion Analyzer, Polk is able to optimize the woofer's motor structure, voice coil alignment and suspension for the best possible performance even at extreme listening levels. The PSW108 utilizes a powerful motor structure for a higher BL responses (the measure of the motive force applied to the cone) that results in louder, deeper and punchier bass. The woofer's Compression Circuitry limits distortion at high volume levels.
Amplifier: The subwoofer is powered by a high-current amplifier producing 50 watts RMS/100 watts dynamic power that supplies clean power for loud bass and a wide dynamic range necessary to recreate a life-like experience in your home.
Bass Reflex Enclosure: The PSW108 features a bass-reflex enclosure with non-resonant MDF construction and internal bracing for deep bass impact with superior detail and accuracy. The Polk Audio PSW108 is available in a black wood-grain vinyl-wrapped finish. The powered subwoofer's front firing port allows the woofer to be extremely efficient and provides more bass impact for your home theater experience.
Controls: The Polk Audio PSW108 offers the following rear-panel controls.
Connections: The Polk Audio PSW108 offers the following rear-panel connections.
Note: The PSW108 does not have a dedicated LFE input.
Not Video Shielded: The subwoofer is not magnetically shielded, so it is not recommended to place it next to tube TVs and video monitors. Though LCD, DLP and Plasma televisions are not affected by magnetism you should allow at least 18" of space between the subwoofer and any TV.
Placement: You may place the subwoofer anywhere in your room, but it will perform best when it's on the same side of the room as your system's front speakers. Also, placing the subwoofer near a wall or in a corner will increase its loudness.
