Power Handling Question

Simple question, I have a Pioneer A-35R and a pair of EPOS ELS3's.

Pioneer is rated at 65W RMS, Epos are 100W max (no idea if this is for both together or for each).

Would I risk blowing them if I turned the volume to max?

Looks like each speaker can handle 100 watts. I don't know why you would need to turn it that high, but the speakers should be fine.

Wait for someone else to reply before you try this, though. I've erred before, and I will again.

Yeah, that's what I've been thinking, but at half volume they're already making huge sound, so I have no idea how they can go higher (they will need to for a party). 100W max might not mean 100W RMS, but then I heard respectable companies like Epos usually don't underrate their speakers and 100W Max really means 100W RMS...

YES!

You can easily blow your speakers if your amp clips or distorts, even if the amp's power rating is lower than the speaker's.

So should I just stop turning it up when it distorts? Or this a stupid question for a forum where people aren't as irrational as me?

I've been told that it's actually worse to crank up a receiver that doesn't have as much power because it'll clip easier. Just try to get a feel for when it starts to distort and don't go past that.

Some speakers list the power handling as a maximum figure, some quote as a continuous figure. In the past I have had speakers that have been listed as 100watts peak power, with 50 watts continuous power. Some speakers simply list a maximum SPL (sound pressure level), this can be calculated (not entirely accurate but close) as every doubling of the amplifier power produces 3db SPL increase... ie. speakers that are rated at 1 watt = 93db at 1meter, would be...96db 2 watts...99db at 4 watts...102db at 8 watts...105db at 16 watts...108db at 32 watts...111db at 64 watts (it takes 10db SPL increase to interpret a doubling in volume)

It is easier to overdrive speakers with an amp that does not have enough power and is driven into distortion than with an amp of more power that has lots of reserve.

If you hear any distortion from your speakers you are too loud. Turn the volume down slightly and put a mark at the volume setting. Do not go above this level until you have cash in your pocket and a short list of your next speakers

Okay, thanks for all the advice guys I won't turn it up past distortion then.
