Question: Will I overdrive these? If I buy the Yamaha RX-V471 which has 105 watts / channel, will that be a problem for these speakers which recommend a max of 100 w/ channel?
Document: Great deal! The speakers sound great, better than expected. You can buy them with your eyes closed. I have them connected to a Yamaha RX-V667 7.2 Channel Home Theater Receiver, a Yamaha dock station, a Sony PS3 and an LG LED 42".
With a maximum input power rating of 100 w/channel these speakers are ideal for my needs.The Polk Audio RM705 5.1 Surround Sound Home Theater Speaker System components are sleek and modern looking. The sound is splendid; crystal clear and beautifully reproduced.
Unpack it, set it up, connect it to your receiver, and you've got the excitement of dynamic, thrilling surround sound with deep bass for movies, games and TV. "The all black 6 speaker (5 satellite speakers, one powered 50 watt subwoofer) Polk Audio RM705 Surround Sound Speak System is a 5.1-Channel, Home Theater Surround Sound System with a recommended amplifier power input of 20 -100 w/channel into 8 ohms of impedance and an overall frequency response of 120Hz - 22KHz.
I bought this speaker set for $199. It sounds really great with the Yamaha RX-V473 Receiver after you adjust the channel EQ to ramp in some more midrange. I think these speakers would be perfect if the front right and left speakers were slightly larger. The sub sounds good. I used 14 ga RCA speaker wire, which may have helped. It would also be nice if they used binding posts instead of spring clips and the sub did not require a Y-cable to hook up.
My review usingYamaha RX-V371BL 5.1-Channel A/V Receiverwith these Polk RM-705 speakers:These speakers sound great with classical concertos to thumping Dubstep, and Blu-ray movies with Dolby HTS-HD are simply awesome.I searched for a while, and decided to buy these Polk speakers because of high reviews of the center and surround speakers. I figured, I could always upgrade the Sub later if needed.
I have this system paired with a Yamaha RX-V573 and the results are outstanding. No complaints at all. I will recommend it.
I usually look at these reviews to help me with my purchases, so it's only fair that I write one to help someone else. I just purchased this speaker system and I'm blown away. The sound is so clean and crisp and very bright. I have this connected to a Yamaha RX-V661 and the sound is amazing. This is perfect for a medium to large room. If you want a BIG sound without the bulk and the high cost, I highly recommend this. The set up was easy.
If you like really hard hitting bass, this one is just a bit weak. The three houses I have put this setup in all really enjoy it with no conplaints of lacking bass. I have set two up with Yamaha RX-V663s and one with Harman/Kardon AVR 354. The Harman seemed to be just a bit better sounding but could just be the room setup. Bottom line is these are a great buy!
If your receiver does not automatically calibrate the speakers, you will need to find the settings that best fit your listening preference. My Pioneer VSX 521K receiver set the crossover at 100 and all speakers to &#34;small&#34;. Before running the calibration, I set the sub woofer to &#34;max&#34; on the crossover and 50% percent on the volume, there is also a phase toggle and I set it to zero.
These are a great tribute to polks line up. For the music I listen to, these exceed much more expensive setups that I have heard.For my setup I used aYamaha HTR-5063BL 7.1 Channel 630 Watt AV Receiver (Each, Black)that has 90 watts per channel, which fell right right in the recommended wattage for the speakers.
Answer: p griffin is correct. Pushing any speaker system with an underpowered amplifier is often more dangerous than overdriving speakers. Just be realist about volume. If you are trying to shake the walls of a 30 by 30 foot living space - its not going to happen with this system. Many $500 plus amplifies have built in protection circuitry: they will shut down when hot. If driving this system too hard, you should notice that the speakers are clipping. Its not difficult to recognize. If so - back off the volume.
