How loud?

[EYEdROP0]

Hello everyone. I have a Yamaha AX-592 reciever with klipsch rb-5 speakers. I have blown many crappy speakers in the past from over driving them when I was young and into bass. Usually, it dosent take long for them to blow. Of course I dont do the same to my current system. Ive never turned it past half way, and usually the volume is at around 25%. My main question is how much can these things handle? I have alot of stupid friends that come over. Alot of them are like "Dude that sounds awesome, turn it up all the way!". Im worried that one day they will just crank the **** out of it and overheat the reciever or blow the speakers. My neighbor cranks his system for hours straight every day. I havent met him yet, but I can hear that he has a good hi-fi system. His stuff doesent sound blown (not form next door anyway). Then again, hes probably running more watts then me. What do you guys reccomend I do to keep my system alive?

Your integrated amp can't put out enough power to overwhelm your speakers which are capable of taking 150w continuous and up to 400w peak. Your biggest concern should be clipping which occurs when trying to drive the speakers louder than your amplifiers output capabilities; this may trash your tweeters.

Having said that, your speakers have a sensitivity of 96dB/1watt@1m and driving them to clipping will probably cause deafness.

In other words, don't worry about it.

Is there a possibility that the voice coil can overheat after long periods of moderately high volumes? What about the receiver?

No, you won't "overheat your voice coils" by playing them loud even after long sessions.

Like I said, clipping should be your main concern and unless you live in a barn or your friends that can't keep their fingers to themselves are deaf you probably don't have to worry about it.

If you still want peace of mind, then add an external amp - a relatively cheap Behringer pro amp like the EP1500 will do the trick.

Remember, Klipsch produce some of the more sensitive speakers out there and they don't need a lot of power to play REALLY loud.

Clipping your yammy would be the chief cause of damaging your speaker, not over heating.

Ok, gotcha. I always knew clipping was a bad thing for the speakers. I just wasnt exactly sure because different people say different things like "too many watts on a lower rated speaker will blow it". Now I know for sure its not true. Thanks guys.

Klipsch RB-5

Are excellent classic speakers last manufactured until 2001. They have a high sensitivity : 96dB @ 1watt/1meter which means they will play very loud with low power input.

As far as clipping, that typically happens when you try to drive low ohm (averge impedance of 4 ohms or less) at a high loudness setting. A lower ohm speaker doubles the current on the AVR and typically there is protective circuity on the AVR to prevent overload; sometimes it clips and soemtimes it actually poweres-off AVR. The clipping puts out a signal that is flat on top, i.e. clipped. That it hurts a speaker is a old wives tale. The nominal impedance of your speakers is 8 ohms and the power rating is 150 watts continiuous and 400 peak; you should experience no problems even playing if deafeningly loud
