since the 12pw seems to have a decent range
I think it is a better fr than the A12p. Response to about 10k. Give yourself 2 octaves that means anything up to about 2.5k.

Hey guys!

I was thinking about trying the 12PW fullrange, in 3 ft^3 @ 23hz (-6dB Extended Bass Shelf). Xmax is completely fine down to 10hz at 3.5W/ 93dB @ 100hz in Box Sims. I was planning to use this with a 3.5 watt SET amp, so it works out perfectly!

20hz Xmax is exceeded @ 12.4 watts... but any rogue sub 20hz frequencies will probably destroy the thing, with cone travel up to 16mm at 10hz.

-3dB @ 60hz
-6dB @ 23hz!!
-9dB @ 20hz!

Enclosure dimensions would be 24" high, 18" wide, and 12" deep. Similar dimensions/look to the JBL L100 Classic, for that "retro" look.

What do you guys think?

I am not a big fan of that kind of alignment. Something that came about with drivers that canít actualy di decent bass. Scott's ML-TL get simialr extension (and i expect smaller)

And unles syou use 2, the sensitivity will not exceed the 87-88 dB 1w figure. And given that it is extended bass shelf something less than that (typicaly 3-6 dB less).
