well I am having my whole system installed at a shop I was either getting the p1 rockforte 10 ported or 2 10 inch primes sealed. When u say tight bass do u mean like a accurate bass where as ported is just for noise?nope ,dont know where you got your info.ported will be alot louder ,sealed has a better bandwidth and tighter bass .usually ported at 32 htz is a very good box,if this helps at all.
