I already have my own thoughts, but I want a general consensus. Since a ported enclosure limits the cone movement of the driver at the resonant frequency, and when using a large ported box the responce has a bump at that frequency. What do you think makes the biggest SPL difference, the driver or the enclosure AND WHY !!!!! Engineers and tech freaks need not answer.

I believe that both driver and enclosure play equal parts in determining SPL. A ported box designed for a Stroker will probably not be anywhere near as loud when loaded with a driver designed for sealed applications. And a Stroker won't do *****in a sealed box.

Whew, thought I wasn't going to be able to reply...
Only occasionally is the response bump right at tuning - usually it is around a half octave above tuning, right where both the vent and driver are contributing lots. The reason you get more output near tuning is that the vent is resonating the entire air volume of the enclosure - not just the displacement of the cone. Provided you have a large efficient port this coupling of box volume to cabin volume can be very effective. (ooooops - the 'secret' to the VT???)
How's that for not too technical???

And that's the bottom line, cuz: LORD DUKK SAYS SO!
