Wattage is linear but dB is logarithmic (I believe). That's why 10x wattage doesn't always equal 10x loud.sal paradise wrote: ↑Fri Feb 03, 2023 2:50 amWattage is logarithmic, not linear. 5 isn’t half etc.. is it related to that?
The relationship between an amplifiers wattage and it's subsequent output in dB is a complicated relationship...factor that in with an attenuator that has a dummy speaker (often at a fixed ohms and with its own efficiency) that then interplays with the real speakers, and their ohms, efficiency and their relationship with the amp and you end up with a VERY complicated and unpredictable outcome of perceived volume.
I'm sure Tony Balls or Brad or someone can come in here and tell it all better (with numbers and stuff) and with proper education and experience on the subject as I'm just an amateur hobbyist with borrowed and flawed knowledge.
