Iv got 4 DC lvl-3 15's The box I built is chambered (two 15in subs per chamber)
and each chamber is 8.8cubic ft after sub's displacement... How many 6in round
stright pvc ports per chamber should I have

I went to http://www.psp-inc.com/ and my results tuned to 34hz
with 3--6in round straight ports per chamber 18.08in long each

Or should I go with 4 ports per side? cuz I hate that air noise when the ports are
not big enough?

3 per side is enough I would think, are you made of money to buy 6 total?

For a daily setup I'd go with two on each side. For spl go with three each.

The only thing I dont want is that port noise where it sounds like high pressure air
coming out of the port...Will I be safe with two 6in round ports per chamber for sure??
