Box size and tuning for a low end monster

[hatedonmostly 5,000+ posts]

I currently have one AQ SDC2.510 in 1.5 ft^3 @ 40 and on 900W. My new setup is going to be four RE RE 12's on 1200W.

For the new setup, I want it to be a low end monster. This is going to be in the bed of a single cab Dodge Dakota. I want to be able to do hairtricks, which I don't think should be a problem considering how small the cab of the truck is and how much cone area I'll have.

For the subs, RE recommends 1.25-1.5 ft^3 @ 35. Is 35 really low enough for hairtricks, because I see a lot of people tuning lower for them.

I was thinking 30-33 Hz, but also don't want to lose my high end (40-50). But would I have to worry about that? Considering four 12's is six times the cone area of one 10", wouldn't it still be louder at 40 Hz, even if the box was tuned as low as 30?

And for box size, I have no clue. I see a lot of people with groundpounders have bigger boxes. 4x1.5=6.0 ft^3, or should I make it bigger?

All opinions would be appreciated...

I think a tuning of 32 hertz would work well for you. I don't think it is possible to lose output at any frequency when going from a single 10" to 4 12"s.

Thanks man, it's good to see you're reinforcing what I'm thinking. Anyone else?

I agree with the lows 30's tuning. If you make the box bigger it will decrease your mechanical power handling. I had an Fi Q on 500w in a 5.5 cube box. It hounded on the lows. One problem with the bigger box is that the higher notes sounded like ***.
