Kris, I agree with you about the unobtainable 300Hz.
Had really hoped for that, but so far no go with my set up:
An old Oris-150 with a 4" throat wood adapter/cradle that John Sheerin made for me,
with the 2482 playing out the back, so you see the entire 4" phenolic diaphragm. Room logistics inspired this solution.
I'm not sure it is ideal by any means, but it works fine.
I can use a relatively large coil, 6mH, on my TAD 1601b. They measure 6.5 ohm.
The 2482 is filtered with a first order PLLXO at 300Hz. This should likely be raised a bit.
I wonder if an exponential horn would raise the bottom slightly?
Also, what could one expect from returning to the 2" throat?
I know nothing about loosening suspensions.
