wow the calc says 12" long so make them 12" long including the port. i think they are like 17" 3/4" long the way the come so cut off 4 3/4"

the flares add how much length?

the flares are like an inch each or so. get a tape measure and measure them

Are you sure 2 4's will give you enough port area?comes out to be 5.288 in^2 per cube

I did not design the box....did the best with the dim given

and with aero's you would dbl the 5.288

you dont double it. i really wish someone didnt say aeros need half as much port area. square ports are 12-16 and aeros are like 8-10 which is roughly half. which is way i said 3 4" aeros would be better it would give you 37 square inches of port area for ur 4.7cubes which is 7.8 square inches per cube. but the ports would need to be like full length to have similar tuning

lol i told u it was gonna die

2 4" ports is really small for a box that size. And each flare is 2.5" long.
