Okay since i was vague or open on comments foe help on what the AB XFL15s like box wise lets narrow it down.
I want lows, something tuned to 28-32hrz.. 3.8-4.5 cubes. I have wiggle room in box size. 44"L - 24"AD - 28"H is my max. So any help would work. Just want a good street pounder.. Ported.. 4th Order etc..
So i have my box built. Sealed for now. 4.6cubes net sealed. Building my square 6×6 port soon. Pretty impressed with the lows and loudness on juat 500watts in the sealed box. Once my new wires and deck gets in ill put the port in do the big 3 and wire it to 1ohm and put 1k on it.
