ZforMe

Just ordered my Zenclosure box with a 12" cutout (1.18ft3 sealed box). I'm planning to start small (use my existing equipment), then move on to bigger and better things.

Initial setup:

Infinity Perfect 12" 4 ohm svc powered by a Best Buy version of Rockford Fosgate 250aii (250rms when bridged).

The future:

I'm strongly looking at the following subs (i'd like to keep it under $200, but i've listed some models that are higher than that):

FI SSD 12" 1 ohm dvc ($179)
FI Q 12" 1 ohm dvc ($244)

Image Dynamics ID12D4 V.3 4 ohm dvc ($179)
Image Dynamics IDQ12V3. D4 4 ohm dvc ($279)

Ascendant Audio Arsenal 12" 4 ohm dvc (no clue on cost)
Ascendant Audio Chaos 12" 1 ohm dvc (no clue on cost)
Ascendant Audio Havoc 12" 2 ohm dvc (no clue on cost)


Amps I'm considering:

Audioque AQ1200D run at 2 ohm ($249)
Hifonics Brutus BRZ 1200.1 run at 2 ohm ($279)
Sundown SAZ-1000D Run at 2 ohm ($315)


My goals:

SQ first and foremost, and i really enjoy super low frequencies. But i don't mind being able to melt peoples brains on the side.

What would be the best setup for SQ and hitting the super low frequencies?

I'll also take suggestions for different ohm setups, but I want best SQ first.
