Hmm, I thought this cab was the SHV, which IIRC was listed as being 9 ft^3 and the one Todd had the drawings of, or is it an Iconic Manufacturing custom?

If I could get an extra 10-20 Hz lower, I'd prefer that.
As a general rule, the point of diminishing returns is Vas/1.44, though if driven with a high output impedance, up to Vb = Vas is desirable due to the increase in effective Qts and why cabs tended to be relatively huge way back when.

Tuning to Fs is desirable, so with a large enough cab it can often be ~flat in room all the way down due to room's contribution and/or with some form of EQ to trade some efficiency for tonally balancing it.
