how you use tube ports?

[fi audio]

how do you know whether or not to use 2 tubes or one and do you just tune it by cutting down the tube? is there caculators or a guide on aero port enclosures?

if its flared u can generally get away with less port area...

for a single ten..and maybe a 12 u could get away with one 4"aero

for a 15 u would want at least two or three...

i just guestimate...aeros are more efficient than slot ports
