Designing a Sealed enclosure using a M130 driver(*)

Danny,

A fairly easy question you can answer on top of your head. I still own 2 units(New) of your M130, 5" drivers(in fact I own 4units so far used 2 units).
I found the midrange performance to be very good. I want to design a sealed enclosure for this unit. So can you advise me:

1. Optimum size of the enclosure, for the maximal flat roll-off at the bottom end?
2. What is the -3dB freq. at the bottom end?

BTW enjoy your Youtube channel. Thanks.

* I want use them as Omnidirectional driver, so no baffle step is required.

You'll need .26 to .28 cubic feet of air space.

The -3db down will be low 70's but with a gradual roll off.
