Some of what I found

Aperiodic
Aperiodic enclosures utilize an external membrane to dampen the woofer and flatten out the impedance curve of the
enclosure.
Pro's: extremely small enclosures, very flat response, excellent low extension.
Cons: low efficiency, usually needs large subwoofers to perform, EXTREMELEY difficult to design and tune properly.

ok so everything I've read so far says they are perfect for SQ but a pain in the a$$ to build and an even bigger pain to tune.

that's about it.
I use two RE XXX 12" in an AP box in my car.
each sub gets ~1300 watts.

Transmission line enclosures are excellent for SQ as well. A well designed ported box can outdo sealed IMO, with ported you can control the level of damping at resonance, something you can't do with sealed. You just don't get the benefits in group delay that AP and TL offer you. Infinite baffle (or dipole) is great, too.
