Onkyo Cable Amplifier

Introducing a complete home theater audio solution for people who crave true cinema excitement without breaking the bank.—the RM6750. The integrated Power Port Bass Vent designed right onto the back of the compact Satellite & 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. The RM6750 comes with its own subwoofer module, an 8 inch long throw driver and high current power amplifier for real ground-shaking bass thrills.

Heffernan 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. 103 of 104 people found the following review helpful. Fantastic Speakers By T. Anderson I do consider myself to be picky when it comes to electronics. And I am absolutely floored that speakers this good can be had for a price this low.
