Isobaric sensitivity question

Have a ton of dayton bass drivers that need to be used. Hence option to go isobaric
Driver spec is 8 ohm, 85db.
For each cabinet, if I side mount two clamshell per side (4 groups, 8 bass drivers per cab) what sensitivity wd I get? Wd imagine parallel twice and series once to bring it to 4ohm.

Then theres baffle step
Indeed. 😉 Sensitivity is usually for half space.

So if each clamshell is considered to be the same sensitivity as 1 driver, 0dB (also half efficiency but let's not go there). Then the top half here will be +6dB (half space). Then with half the drive Voltage it's additionally -6dB. After this, add the bottom half.

Which makes +6dB half space. At low frequencies that's 0dB.
