just try one you can add more later my box had 4 6 inch aeros and after exstensive testing ended up with just 2 tuned to 27htz and you can always take out the 2nd aero and plug the hole but 1 should be great

why not a single 8

13 inches long for 35

A 15 needs more than 26" of port area aero or not. unless your constricted for space

a single 8 is way to much port area

ok so one 6in flared port is what i will go wit. Will having more port area make the sub handle power better and hit lower notes ?? Just asking some of the things i have been reading

More port area makes the sub easier to unload below tuning, it also makes there be a sharper roll off below tuning. So although it would be loud from 35hz-whateverhz, you'll start to see the response drop pretty fast below that.

i want it tuned so it will be loud but still hit lows should i go 35htz ?

I'd shoot for around 33-35hz...I'm just not a fan of higher tuned boxes.

the smaller port will make it better on lows and musical

big ports work good in walls and bandpass designs

48 inches of port is perfect for a btl in 4.3 cubes. 11 inches per cube
