My Sony STRDH590 went into protect mode after 30 min of listening

1. See Page 34 of the owner's manual from the Denon website. It is clearly specified that it will handle 4 ohm loads
2. The Sony receiver won't handle speakers with impedance lower than 6 ohms (indicated in their user manual)

Yet there's no actual 4 ohm use rating by Denon, just an indication that the range is 4-16 (and implied that you should also limit the power of the avr with the 4ohm impedance switch setting). The Sony simply doesn't recommend 4 ohm, not that if you hook up 4 ohm speakers it will not work.

The Denon's ratings:

For the record, I never use the max volume when watching movies, it's simply too loud and I also don't wanna damage the woofers as some scenes make them go super low when it's close to the max volume, I think the overheat happened because it was the first time I was listening to music and I guess music puts a heavier stress on the receiver compared to movies.

 

[lovinthehd]

The music could have stressed it more, depends on a few things, tho. So that's just where you've used the volume dial for movies for the most part? Movies and music are recorded with varying standards, movies adhering to one more than music.

I have watched several movies and it has never gone into protection mode, it's hot to the touch but it has never gone into protection mode, it only happened today when I was testing some music with loud volume, I wanted to watch a concert but I will avoid it until I get better cooling.

I looked at the Aircom AC Infinities, not sure which is better if the rear or front exhaust

I bought one of these when I had a Denon...instead of using the Denon as a toaster which would have been easy.

I still use it on my Pioneer, even though it doesn't get anywhere near as hot as the Denon did....cooling never hurts.
If you are listening to loud bass heavy music like Rap, Hip-Hop, Electronic etc, that will stress your amp a whole lot more than a movie.

You'd need to measure spl levels to compare really. I recently got an Aircom T8 and it works well, but isn't quite as quiet as a cheaper solution (but uglier and with less features) from a pair of speed controlled fans from coolerguys.com (also rear exhaust like the T8). The back of your rack is open, I'd prefer a rear exhaust myself.

This is why I indicated this AVR and it fits the $1,000 budget. We can tell him to go get the an top end AVR and a separate amp but if it doesn't fit his wallet, there's no point.

I made these today, I'll test after watching a movie how hot it is.

That may help, but you really don't have much space there. Can you mount an array on the back to pull heat away?

I could the issue would be fan noise

 

[lovinthehd]

Are those magnets embedded in the feet?

Yup

Yup

Nice! Hope it works out for ya....
