Ears can definitely be deceived as far as frequency presence too

Still going to disagree, ears are *very* easily deceived about level. That’s the whole point of the difference between Magnitude and Loudness

Strongly disagree LOL 
That’s literally the whole premise of the Bose effect.

Wrong context. Sound can be deceiving to the ears, but not level. Its quite noticeable. Unless there's gremlins inside casting spells or something.

Edit: in the meantime, some folk might have missed the discussion & modelling I did on the big boy Paraflex back at the start of this year. Here’s that old thread:


Really enjoyed our conversations and your insight into taking proper measurements. I appreciate your time for sure! Hopefully things work out this weekend as I'm myself interested in a proper test measurement.
Also if you can, please try and get one from the rear of the cab to test rejection. I know its been modeled to say differently, but ears are not deceiving. These things are very quiet behind them, compared to in front of them.

22mm is a commonly available sheet size, I’d trust HMAudio meant what he said LOL
