Since I changed the LF transformer and increase the output stage loading I did address the problem with power limit. It looks like now the midbass does not clip at very high power and has some headroom – that is good. I however not absolutely comfortable about the new midbass configuration. The extras lording gave me some extra harmonics that I killed by the third filter. I also use some acoustic filtering at my triangular wall – something that you guys do not know yet but I will post the pictures as explanation later on in “my new room thread”. Still, I have extra 2 dB of gain in midbass and that set my former last week absolutely perfect midbass configuration to be not as good as I wish.
Thos extra 2dB is a pain in ass. It is simple to kill it by divider in midbass driver stage, this would even add some power to the channel. However, I do not like to attenuate the LF and I asked myself why do not increase the rest of the channels for 2 dB, I do have this option. The irony is that the attenuation of bass for 2 dB is not the same as jacking up the rest of the rest of the channels for the same amount. It shall not be so. also, the almost transition slop use of my midbass do give some benefits – like an ability to virtually decompress some recordings and to hold the bass level properly at wider volume level.
Anyhow, I do not have my piece for now at what level I will be locking the midbass. I will be looking at it over the weekend.
