Its been about 3 years since my last build of 4 15in DC's lol I got married and stuff.
Anyway, im getting ready to build a box soon and i think this time I'm
Going with round ports and i was using the round port calculator from
The12v.com and my simple question is if i want two round 4in ports
do i just double that into the calculator and say 8in round and then the length
It gives me divide it by two ? Right.
I know that sounds like a stupid question, but its been awhile.

Also what's a good hz to tune the ports to for a daily driver needing
good lows ? I for got that too :/
