How can I tell if I am overdriving the amp or the speakers?


I have a Hegel H390 driving KEF Reference 5 speakers and when I play something loud, the upper midrange ( saxophone, electric guitar, piano ) start sounding sharp and annoying. The amp is 250 x 2 into 8 ohms, stable down to 2 ohms and the speakers are 90 dbs, 8 ohm, ( min 3.2 ) 50-400 watts. I’m pretty sure it’s not room acoustics, but.

Thanks.

And while I am play some tunes loud, It’s no where near face melting volumes I’m talking about. I’ll put a meter to it tomorrow and give some numbers, but I’d be surprised if I was much past 85 dbs.

@erik_squires ,

I have been moving some 2’x4’ foam, absorbing panels around as well as some pillows and even a couple of blankets. It’s hard to explain, but the room probably doesn’t have 60% walls and it was worse. Not one wall is solid all the way from side to side. The front wall is the closest with only a doorway (no door)

I just googled the Hegel & those Kef speakers and wow.  If you can go by MSRP, that should be some pretty good stuff.

I hope you understood what I was trying to say.  I probably should stop posting after bedtime.🙁

So this morning after everyone left, I put on several different CD’s and cranked the volume.  I played some jazz and some rock and maybe it’s because it was morning (?) nothing distorted!  I pulled out the sound meter and I got well into the 90’s and the light flashed when I went over 100.

I’m going to try this a couple more times. Listen at night and listen again in the morning.

Maybe there’s nothing wrong with my equipment or my room. Wow, maybe it’s my ears? 

Mmmmmm
