Our take on the Polk Audio RM75 Home Theater Speaker System

by Loren Barstow
Polk Audio

Why choose a pre-matched speaker system?

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.

The Polk RM75 offers exciting wraparound audio effects in a sleek, modern design. These compact, wall-mountable satellite speakers fit beautifully in most rooms, and they're a great cosmetic match for a flat-panel TV. You get two front speakers, one center channel, and two surrounds. Just add a Polk powered subwoofer to complete the system and enjoy full, detailed home theater sound.

Each stylishly sculpted speaker sports a heavy-duty, non-resonant composite enclosure. The included wall-mount brackets let you pivot the speakers up to 180 degrees, so you can easily aim them toward your listening position for the best possible performance.

    System Components: The Polk Audio RM75 home theater speaker system is a 5-channel speaker system that includes four identical satellite speakers and a matching center channel speaker.

    Additional Speakers: If you wish to use the RM75 for a 6 or 7channel surround sound system, you can purchase an additional 107RM7CB single center channel speaker or 107RM7B satellite speakers to fill out your speaker requirements.

    Driver Technology

    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.

    Drivers: The drivers used in the RM75 home theater speaker package are as follows:

    Satellites And Center Channel Midranges: Each satellite speaker features a 2-1/2" dynamic balance composite cone driver while the center channel speaker features two 2-1/2" dynamic balance composite cone drivers, which are lightweight and efficient, resulting in clear, distortion-free midrange.
    Satellites and Center Channel Tweeters:
    Each satellite speaker and the  center channel has a high-performance 1/2" dynamic balance composite semi-dome tweeter for sweet highs and more lifelike imaging.

    Enclosure Design

    Enclosure: The RM75 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 speakers will accept pin connectors and bare wire.

    Mounting Options

    Video Shielded: The RM75 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 RM75 satellite speakers can be placed on a shelf or table top without a stand due to their flat base. The satellite speakers can also be wall mounted using the supplied wall mount brackets which allow the speakers to swivel horizontally. In addition, the RM75 satellite speakers are compatible with Polk's SA-3 floor speaker-stands. The RM75 center channel can be placed on a shelf or table top with the supplied mounting stand and can be angled up or down. The center channel speaker can also be wall mounted using the supplied wall mount bracket. The center channel's fixed wall mount bracket does not angle or swivel.

    my installer talked me down from more expensive options

    Written By joeC, birmingham, al on Sunday, December 19, 2010
    Crutchfield Customer Review (What's this?)
    and I'm glad he did. You have to add a subwoofer to complete the package - the only
    criticism I can come up with. Great sound - huge improvement over the "simulated
    surround sound" single speaker+subwoofer option I scrapped recently.

    As always, great execution by the folks at Crutchfield.

    Good buy for the price

    Written By Ryan, Detroit on Wednesday, March 17, 2010
    Crutchfield Customer Review (What's this?)
    I picked these up to replace some JBL studio series speakers I had at my new house. I wanted something small with good sound at the right price. The speakers are very slick and are currently mounted on the walls in the corners of the room. I am very happy with the installation and the wall mount brackets that come with them are a huge bonus.

    The speakers themselves are good for the price. The JBL's i took down performed better, especially with very high notes - but they were more expensive and much larger with larger tweeters. These speakers will meet my needs at my home and will look much better with my wall mounted plasma. The price is right, so I am happy.

    great stuff

    Written By Jesse, Knoxville, TN on Wednesday, February 25, 2009
    I purchased these speakers and they are the best thing i have ever heard. i have them hooked into a Sony 6.1 receiver pushing about 115 watts a channel. I also have them hooked in with a klipsch 10 inch floor firing sub, and all total this system will make the dang house shake. The highs are so great and the lows aint to bad either. Also I got the stand with the glass on the bottom of them that match these things and they look real good sitting next to my plasma. Oh and the new Batman movie on these things is crazy.

    Polk Audio RM75 Home Theater Speaker System

    Written By Juan J., Jayuya, PR on Friday, January 30, 2009
    Crutchfield Customer Review (What's this?)
    So small and so powerfull!!! for my room 15' x 30'. Surprisingly good bass response. Very fine black finish and excellent high quality grille. Heavy magnets. Very well sound balanced. Very easy installation with sturdy small wall brackets for. Easy connections with clips, but the holes are a little bit small for the stranded monster cable CRXPNW-100. Good dominant central speaker with high speech distinctness in dialogs at low wolume. Very very good performance for the price. Heartly recommended. Excellent as a substitution of my old big speakers of differents makers in my first home theater. Installed with 32" Bravia and Sony Receiver STR-DG920.

    Great Sounding Speakers

    Written By Shaun, East Grand Forks, MN on Wednesday, November 19, 2008
    Crutchfield Customer Review (What's this?)
    I wanted 5 small speakers to finish off a 5.1 in-the-wall surround installation. These speakers are small, good looking, and sound very good. They came with wall-mount brackets and look great on the walls & ceiling. I added a high-power sub & the whole system sounds like a theater should! I highly recommend these speakers. I will surely be buying these again for my other 5.1 theater room (finishing basement). I should add that I am powering these speakers with a 100x7 Sony 7.1 receiver.

    Very nice sound for the price

    Written By Spencer, Winfield, IL on Thursday, September 11, 2008
    Crutchfield Customer Review (What's this?)
    My system is installed in the basement of my home, in a 13x25 room. I can fill up the room with sound. I know that these speakers seem small at first, but they really get the job done. I have them hooked to a Sony 810 and I also have the PSW10 Sub - movies like Star Wars really come to life. I am not disappointed with these, and would buy them again.
