Hello @nitro2

Couple of questions: what is the source? Is it a Beomaster, a tv or other line-level product?
If a Beomaster is used, what volume is shown on the Pentas?
What type of music? Does it happen all the time when any source reaches the same volume?

Type of music does not matter , the 4 of them are connected to a beomaster 7000 , volume on the set around 40 when the "soft clipping "starts on 1 of the 4 penta's ( always on the same unit )

And this problem excists whatever source is played , always around 40 ( ish )

Could suggest that the amp runs not symetrical.
Any DC on the speaker output?
