Speakers: JBL 705P
Stereo Subwoofers: JBL LSR310s (I can localize the subwoofers at any crossover and can post videos of me doing this if you don’t believe me)
My setup sounds DRAMATICALLY better crossed over at 120hz versus 80hz.
At first I thought this might be because the built in 120hz crossover on the JBL also includes a bass boost in some frequencies as described in the manual and the in room response of that boost might be more even than without the boost on the 80hz crossover.
But I’ve since calibrated the bass to the same target curve with Dirac live and calibrated 120hz crossover still sounds dramatically better than the calibrated 80hz crossover. I have 2 sets of measurements for each crossover setting so I’m not misapplying corrections.
Despite supposedly having the same decibel output and very similar frequency responses once calibrated the bass with the 120hz crossover feels far more impactful and realistic. Additionally, the midrange at the 80hz crossover feels boxy, stuffy, bloated. This is quite noticeable on vocals. At 120hz the midrange suddenly feels freed from it’s chains and ready to soar into the sky with the beautiful doves of the sound god.
Can any of you come up with theories as to what might be happening here with science?
