Stereo shutting off at high volume

[Woolysworld]

Well here it goes.shuts down after a point when it gets to crazy levels. So what I have is a Yamaha RX-V465 AV Receiver 525 watt (105w x5)
I HAD a practically new pair of Polk Monitor 70 series 2 Tower speakers which were rated at 275w, I sold them last week. I have a Bose center speaker which I’m not sure of the watts. I think its 200w but when I was having problems I disconnected the Bose.
So now I bought a pair of Klisph Reference Dual 8” Floor standing speakers 600w peak 150 w continuous and also a pair of Klisph Reference 5 ¼” Bookshelf speakers 340w peak 85w continuous for the rear/back of my living room. I bought 12 gauge copper wire and I also bought a 5” electric fan for the receiver which is in a stereo cabinet. (I cut the back out of the cabinet where the receiver is for air to escape. So now I’m thinking of adding a sub.(Heard that may also help with my issue, not sure though) will adding a sub help with my volume issue?

I think you should back up just a little bit.

"Crazy levels" doesn't really mean much. If I were to guess, either the AVR is defective or there isn't enough ventilation around it. The Polk's and most likely the Klipsch's are slightly above normal for sensitivity...around 90-91dB. So when you are running them at only 32watts they are sitting around 105db at one meter (per speaker) which is past crazy and into stupid loud, unless you are listening to them 12 feet away or more.

Have you tried running them with the AVR out in the open where there's plenty of ventilation? Also, don't run it with any boost just have flat eq for now and run the speakers as "small" with the crossover set to 35Hz or whatever is closest to it.

Thanks, I'm trying to put everything in perspective. My system is not used for movies, just for music. Let me ask this. If I wanted to have rear speakers in the room which is 14' x 25’ what advice would you have? I'm going to get a good amp like you suggested. Let's back off from CRAZY levels to just real loud.

With my comment, it's more so that you need to find out for sure what's wrong...or at least rule out thermo-shutdown from being in a cabinet, otherwise the same thing can happen with any amp you buy. This is why I suggested setting the Yamaha in open air and see if it still shuts down at the levels you normally play at.

Even if you have a fan to move air through the AVR, if the cab isn't well ventilated you could have problems. So, if the yamaha works in the open, you'll need to do some work on your cabinet to increase airflow to get rid of the heat. If everything gets corrected, then I'd suggest that the money you were going to spend on a new amp on a good sub instead.

If the Yamaha still shuts down in open air, then it's a problem with the AVR and getting something new to replace it is most likely the way to go.
