matching amp rms w/ speakers

[Beckman]

I thought you said "The common problem with speaker ratings is that nobody listens at 125 watt RMS,EVER." Must have been someone else.

The original question was about matching amplifier output to speaker ratings. I appologize on behalf of bturk667 if your ego was hurt. bturk667 was just trying to make a point that most sane people listen to music at levels that will allow them to still have some hearing past age 25.

I try to cut through the crap. I can't believe how many times someone asks a legit question (Usually an audio "wives tale") which starts something that gets the original poster nowhere closer to the information they need.

I try not to post anything stupid...well, an occasional "one liner" or tongue in cheek response to someone elses dumb comment...but not when there is a real question being asked. There is way too much disinformation being bantered about by people without a clue, or with an agenda.

My agenda is simple. Buy good hi-fi, don't regret your life afterwards. I fight against bad speakers, IC output devices, teeny tiny power supplies, inflated specifications, using numbers from questionable manufacturers as gospel, using numbers as gospel, and audio ignorance. Less is more. More is not always better, better is always better.

I haven't heard the "matching amp and speaker watts" thing for quite a few years. Thought it had gone the way of .000000X THD. Pockets of resistance remain.

Have a good one. Bedtime for me.

Hello, thanks all for sharing your opinions. However after reading the above I still don't know what to do. For an upcoming (hopefully soon) HDTV and home theater purchase, I was looking at Yamaha's RXA-710, a nice, easy to use receiver. I was hoping I could hook it up to existing speakers.. Cerwin Vega D9 being the best among what I own. I don't get a good feeling that the 90 wpc for the 7 channel receiver can handle moving the D9s?

Make sure the amp has an output so you can use an external amp....run it out of the box and if you still need power grab a used Adcom or Parasound, NAD poower amp and you'd be straight.

The D9's have a sensitivity of 101dB and impedance of 4 ohm's, 90wpc will blow out the windows in your house with the D9's. The speaker is rated for 5-350watts. You could use a 5 wpc amp and play it very loud. Just make sure the amp can handle 4 ohm speakers otherwise you are set to go!

I use a 5 watt amp on my main system and it plays loud, but not as loud as your system would play with the same power.
