Product Description

Amazon.com Product Description

Polk Audio's RM6750 5.1-channel speaker system gives you a complete surround sound solution for your home theater without breaking the bank. The integrated power port bass vent designed right onto the back of the compact satellite and center channel speakers-the same technology used in full-sized Polk Audio speakers-improves lower midrange response and all-important sub/sat blending, taking the RM6750 beyond the performance realm of any other sub/sat system in this price range.

This integrated design reveals midrange with no "hole" in the frequencies between the sats and the sub, for male vocals that are rich and full-not thin and weak like other sub/sat systems. It comes with its own subwoofer module--an 8 inch long throw driver and high current power amplifier for real ground-shaking bass thrills.

Key Features

• Satellites use a 3-1/4-inch (8.25cm) Polymer composite cone driver: lightweight and efficient, for clear, distortion-free midrange. The center speaker uses two of the same high quality drivers for even greater output capability.


• Integrated baffle and grille design allows maximum sound dispersion with minimum diffraction for superior imaging and room-filling sound. Everyone in the room hears clear, well-balanced sound.


• High performance 1/2-inch (12mm) silk dome tweeters for superior imaging and smooth highs.


• Mineral-filled polypropylene enclosures are non-resonant for great looks and natural sound.


• Individual satellites available to accommodate 6.1 or 7.1 channel systems.


• Integrated keyhole slot wall mounting brackets (two keyhole slots on center channel speaker) allow for easy wall mounting, with no extra brackets or wall mounts to buy; threaded inserts accept popular articulating brackets (sold separately).


• The Subwoofer, in a compact ported enclosure, features an 8-inch Long-Throw Dynamic Balance poly composite driver for longer driver excursion and better linearity, resulting in big, musical bass.


• Built-in Subwoofer power amp (50 watts continuous/100 watts dynamic power) with active crossover offers the control you need for real home theater thrills and big, musical, accurate bass. Features variable low-pass filter and volume (level) controls, as well as phase switching toggle, and signal-sensing Auto ON/OFF, for even more control and convenience.

Customer Reviews

I have not written product reviews on Amazon before but I find them to be extremely helpful and want to give some payback. In particular, I found the home theater system and home theater speaker reviews to be very useful.

The Polk Audio RM6750 5.1 channel home theater speaker system is phenomenal and an outstanding value. I had originally been looking for a home theater in a box system to mate to a newly acquired 37" LG LCD HDTV. The search was partly precipitated by the demise of the older generation DVD player we owned coupled to a failing 10 year old Onkyo surround-sound system. As I poked around on-line reviews and shopped Circuit City and Best Buy it became clear I could get more value and flexibility buying a receiver, an upscalable DVD player (improved picture with regular DVDs on HDTV) and a new speaker system than with home theater in a box.

The room housing our entertainment hardware is a family room -- 20 X 20+ with a vaulted ceiling, fireplace and hearth on one end and lots of upholstered furniture -- a relatively big space to fill. However, I did not want bulky speakers. I was initially intrigued by the Amazon reviews on the Yamaha NS-SP1600, quite favorable, great price and describe great sound output for small speakers. Sadly, I couldn't find these to purchase anywhere locally, nor get them from Amazon or even from Yamaha. I heard a set that I think were badly wired at a Best Buy -- good sound, not much power. Yamaha's next higher line NS-SP5700 were bigger and clunkier looking than I liked and I couldn't find reviews. They sounded OK in a poorly set up demo.

I kept shopping and was very happy I did. I looked at speaker manufacturers' websites and rapidly coned down on the Polk Audio RM6750 as looking to fill the niche I sought balancing size, quality and price. I was able to listen to them in a well set up home theater showroom at a local Circuit City and was immediately sold on the clarity and power. I bought a set for $299; they're a steal at that price and better on Amazon for $249.

I brought them home, hooked them up with the Yamaha 5930 receiver ($179) and upscalable Toshiba DVD player with HDMI ($89) I had also acquired and connected to the HDTV. This is a true dream system! The speakers generate enormous high quality sound. We tested them out with "Master and Commander" -- clear highs from all, natural voice from center channel, terrific oomph from the subwoofer and amazing surround sound experience in the early battle scene. Next test was a Down to the Waterline on a Dire Straits CD -- I heard notes I never knew were there with great balance and driving bass. (The Yamaha gives multiple modes of play including 2 concert hall variants, 2 movie variants, 2 and 5 channel stereo and a few others I haven't played with yet.)

I have filled this large room with amazing sound without going beyond 60% of full volume. I am a very happy customer.

I had looked at the low end of high-cost speaker lines -- Bose and Cambridge Soundworks. With them, you get single speakers in front and surrounds as opposed to 3+" plus tweeter in each of the Polk Audios. Also, the Polk Audio RM6750s sound better to my ears and cost much, much less.

Speaker wiring is straigtforward; wire is not supplied and best to buy/use thick gauge to handle power. Speaker set up instructions from Polk are relatively meager, especially about the subwoofer, but their website is very informative and makes a compelling argument for hooking up subwoofer in parallel with front speakers rather than using subwoofer port and sound is terrific this way.

Polk RM6750 5.1 Speaker System

Before reviewing - "thanks" to everyone who did likewise. I recently upgraded a few elements and placed a lot of emphasis upon user reviews to guide decisions between rival components.

As for the review, first a description of my home theater and audio system: Dell WD4200 1080i HD Monitor, Yamaha RX-V661 A/V receiver, Toshiba HD-A2 HD DVD player, Polk RM6750 system as the "A" speaker set, Klipsch Forte's as the "B" speaker pair. The listening/viewing environment is a carpeted, 12 x 14 room opening on one narrow side with an archway into a larger room, with the TV, front speakers, and subwoofer placed on a long wall. The RM6750 center speaker is installed immediately underneath the wall-mounted TV, the front right and left RM6750 surround speakers atop the Forte's in the room corners, the subwoofer on the floor, and the rear right and left surround speakers ceiling-mounted and directed downwards to a sectional sofa at the rear of the room. Since my receiver allows user-defined selection of the LFE crossover frequency, I wired the RM6750 sub to the receiver's sub-out, set the receiver LFE lowpass at 160 Hz, set the sub LFE lowpass to 160 Hz, and set all other RM6750 speakers to "small".

My view based on both surround and stereo playback programs is that the RM6750 represents a huge upgrade for folks interested in a basic surround system - particularly if the alternative is listening to standard TV speakers - though the system is not a substitute for more refined audio monitors if the primary content is music. At this pricepoint what are remarkable are not the system's weaknesses but its strengths: the center provides clear dialog, the four surrounds are bright and forward, and the sub adequately if not accurately renders the "thumps". "thuds", "whacks", and harmonic base tones associated with studio music tracks. Using a variety of Dolby and DTS-encoded film audio tracks, the surround-scape created by the RM6750 was unexpectedly good: clear, defined, well-separated, and without obvious flaws in stand-alone listening. The subwoofer pumps out a lot of sound - even with the volume set to the unit's midpoint - but it tends towards the "thumpiness" I associate with over-driven car audio: no buzzing or rattling, but just short of that. However, as movie audio effects emphasize presence over accuracy, this may be by design and the results for standard surround-sound movie audio are impressive.

The system's weaknesses stem from the inability to accurately and smoothly reproduce standard music. To minimize listening bias, I performed several hours of A/B testing of the RM6750 in most listening modes provided by the RX-V661 with the Forte's as reference using classical and rock CDs as input material and my wife and daughter as blinded panelists. The Fortes were hands down smoother, crisper in the highs, and more accurate, deep, resonant, and non-boomy in mids and the lows. The largest difference was in the low-base response, where music material with complex deep-base (some Floyd tracks in particular) was boomy and mushy on the RM6750s but clear and seamless with the higher frequency tones on the Forte's. Pound for pound, however, the RM6750s were surprisingly good competition for the more expensive horn-driven tweeters, midrange, and base of the audio monitors playing music: the Forte's, though aging, were among the best speakers made at the time I purchased them (I replaced a set of Bose 901s), cost 5 times then what I paid for the RM6750s now, and do not provide a dollar-for-dollar linear sound advantage. One would be hard pressed to say the RM6750's suck for music listening and minor deficiencies in accuracy would be difficult to detect - expect for obviously inaccurate deep base - in the absence of a superior comparator.

The bottom line in my view is that if you bought a big TV and don't have a surround sound system, spending another $250 for the RM6750 will render an outsized improvement in your home theater experience. For those who like loud low-bass and don't necessarily care if it is a bit jarring and "thumpy", you could use this system for both home theater and music listening. For those who prefer accurate music reproduction, only the most budget conscious should consider the RM6750 a standalone solution to all their listening needs.
