The AE driver in my sims reaches over x-max at 25hz with 200 watts while the Fi still has plenty to go. The AE did have more spl at 10hz than the Fi at 200 watts but only one can be used with 200 watts. The FI can double that for 3 dBs more too. What am I missing? If 8 AE would have given me more spl down low than the 8 Fi's I would have went that route since the price is similar.
You're not missing anything. All I intended was it would be interesting to see that sim with an AE driver.
You got the right drivers, displacement wins, when one has power and EQ tools, ... you'll have more Sd, more Vd. Eight 18s will barely be moving 99% of the time.
Utilizing the 8 18"s, with massive amounts of displacement, keeping both excursion and VC current low, you're lowering the non-linearities including linearizing Bl(x), and lessening any inductance variation related harmonic and intermod distortion by again keeping both power and stroke to a minimum, Le(x), Le(i).
No regrets MK, the baffle wall IB should be stunning, both measurably and subjectively.

I'd say you've increased your relative*
Vd capability by 2x-3x, compared to what you had before.
*as I've shared before, I believe
the eD drivers rated Sd was generous. The piston area is really small relative to other drivers of a similar trade size. Hence the 2x-3x comments. Admittedly, speculative.
