Hi all, Does any one know if the 2231h speaker is designed to push to the rear when connected properly? I noticed this on my 4350b. On my 2231a speakers it pushes forward. Thanks, Ken

Hi Ken;

I am pretty sure that by design all of the old JBL drivers cones move toward the magnet with positive applied to the red terminal of the driver.

I think the 2012 ans 2020 were the first to make the jump to what is now considered conventional polarity.

Thanks Barry, I think i was wrong about the 2231a moving forward. Any thoughts why it is this was?, Have you ever checked yours?, Ken

Hi Ken;

Mine are "hacked" and have 1500AL's in them with no passive elements at all.

Hi Ken,

Positive voltage on the black 2231H terminal has to move the cone forward.
