Could I blow these speakers??

I've got a question for you guys:

--> My surround sound and back speakers are in-wall Klipsch R-5650-s:

---> and my AVR that drivers just the in-walls is a Denon AVR-687.

A question that I have is, I need to crank the Denon 687 close to max to get a good level of sound out of these speakers. So, as a question: Am I in danger of blowing these speakers [due to clipping]?

The specs of the speakers and AVR are:

Klipsch R-5640-S: 50 Watts Max; 200 Watts peak; Recommend Amp power is 100 Watts
Denon AVR-687: 75 Watts

I'd hate to blow in-wall speakers--what a pain that would be to retrofit.....

Make the speakers buy you dinner first :7:


The Klipsch don't have wide impedence swings, are fairly sensitive, and have a workingman's reputation for accepting tons of volume...you should be well within working parameters.

Took me a couple minutes trying to figure this out.... Finally did, what as shock. Maybe I should have said 'damaged'???

Yeah, I knew it was unfortunate as I typed it.

Seriously though, I doubt you'll have any problems with the speakers. Does your receiver have pre-outs? If so, there's always the possibility of adding an external amp for your front three speakers to alleviate any concerns.

No preouts, it's a low end Denon. I'm thinking since the max peak for the R-5650-S is 200W, that the clipping from a 75W source should not harm them. Do you agree??

Thanks,
Stan

I agree unless you're watching films with an extended, uncut, 20 minute explosion scene with all speaks running at their peak...otherwise, happy viewing and cheers. :thumbsup:

First, generally, not much sound comes from the surrounds.

Second, your receiver should provide more than enough power to safely drive them to ear-bleeding levels of loudness.

Third, even if you do manage to push it beyond the physically painful limits described in the second reason, you should be able to hear their distressed pleas for lowering the volume.

Finally, if you somehow manage to go beyond reason three, it's more likely that it's your ears that are blown, not the speakers.

takes going all out to get decent volume, then there is a very good possibility of some of your positives connected to negative posts on you speakers. even one wrong connection will screw everything up.

Trust me, i have 2 pairs of Infinity RSa and one wrong woofer connection threw everything off. Bass and all.

Easiest way of checking is to connect the positive on the speaker wire termional to the positive of a battery, of course the negative has to be connected as well. Low voltage please.

Klipsch speakers tend to have a high sensitivity so your problem is peculiar. Have you matched the levels of all the speakers with the tone (noise) generator and an SPL meter?
