port calculation, gross box or minus the port itself?
I'm a bit confused, there's no surprise.
The port length calculation I used is this ((14630000*(D/2)*(D/2))/((Fb*Fb*Vb*1728)-(1463*(D/2))))
Sticky confirms gross volume is without port or subs volumen removed.
This is 2 x E8's, 0.6 cu ft each. for 30Hz = 4.5" dia port with something like 40" port length
That would be like tacking an extra 0.35 cu ft of folded port onto the 1.2 cu ft of box.
what do you think? 40" sounds a lot.

JL 6.5's in the front doors
AP1040 bridged driving them.
2 Sundown E8's in 1.1cu ft tuned to 30Hz.
700rms @ 2Ohm Cadence... let's see what the the E8's can take
