Speakers pop when amp turned on

[spwath]

When I turn on my receiver (Onkyo tx-sr606)

My speakers make a semi loud deep pop sound.

Is this normal?

Can this damage my speakers?

[iamdarkyoshi]

It is normal, and no it shouldnt damage them. its the DC offset cap charging likely.

[manikyath]

my amp does this as well.

OK good.

I just didn't want them to actually pop.

[Enderman]

My receiver doesn't make any pops at all...

My receiver doesn't make any pops at all...

Neither does mine. but it does a soft start on the amp circuitry. It happens with cheaper transistor amps. My portable 30W speaker that I made has no pops due to it being a class D amp.

My onkyo amp would have been like 400-500$ back in 2008

I kinda meant simpler design when I said cheap. Its not really a huge issue. My receiver... I have no idea what the price would have been back so long ago.

It actually can damage the speakers, I have broken 2 sets of Studio monitors by the "Pop" you hear it will eventually rip the cones and need reconing.. Turn the amp on before your speakers and it will be fine.. Source: Me, Somebody who works in a studio and own his own

With @spwath 's new speakers, they should be fine. I can see how it would damage them, but not if the amp and speakers were of decent quality.

I cant turn on the speakers. They are passive.

There is no way to turn on amp before speakers.

How loud is the pop? If its not any louder than you would ever crank up the speakers to, its probably fine.

It doesn't really matter the quality, The popping is a Transient producing a Square-Wave making the speaker cones extend farther than they are meant to depending on the Gain (IE: Volume) since speakers aren't meant to produce Square-Waves at a medium-Loudish volume..

If they are powered before the amp then make sure the amp volume is turned down before you turn it on and it shouldn't make the pop.

IDK how to avoid it though

IDK, I dont think its that loud, its normal volume.

I am aware of this, I have rebuild speakers and designed audio amps. But if its a DC offset cap causing the spike, disconnecting the speakers and waiting for a bit wont solve anything unless the amp has a resistor in it to discharge the cap when speakers arent connected.

Yeah, i could do that, it seems to work

[iamdarkyoshi]

Some amps will still do it. If the preamp is whats making the sound, then turning it down MIGHT solve it. but if the driver amp is what makes the pop, volume wont matter. Edit: he said it seems to work, so must be a preamp turning on.

although it could be that it worked because i only left the receiver off for about 5 seconds

[CerialKiller]

the pop can be bad for the voice coil. make sure when you turn on or off your system that your levels are low

If you're turning the speakers on, they have their own internal amp. Two amps equal more power equals duh. With a single standard AVR he will be fine.

[Vozella]

I have very large speakers and I can confirm they pop when they start recieving or lose power. I usually control the power with the switches on the back though so they won't pop. 

I had a chorus teacher tell me that I shouldn't let them pop since it hurts them. Not sure if this is true.

Dont run an amp into an amp unless the second amp has a speaker level input...

Yes it is true that it damages them.

It's a good thing I have been doing it properly then.
