[QUOTE="squeak9798, post: 534553, member: 555320"] I think you may have your terminology a little off there, or I am reading it wrong. The ported will have greater low frequency [I]output[/I] down to the tuning, but a sealed with a decent Qtc will have greater low frequency [I]extension[/I] (i.e. sealed can play lower than a ported box, but down around the tuning frequency the ported will have greater output). Also a good time to mention Hoffman's Iron Law: You can only have two of the following three at any one time; 1) Small Box 2) High Efficiency 3) Low frequency extension If you want any two of them, then you must sacrifice the third.
