[QUOTE="huricaine, post: 7173219, member: 622532"] Sealead bloxes have less group delay, which means it has a more linear response on the rolloff. Like a 6db/octave highpass xover vs a 12db one for example, so it "sounds better". Anyway, you can sacrifice a little output at tunning for a lower extension, you can get the extension very low like 20hz, which is good. Depends on the sub, competition subs with an fs of about 46hz, and a low Qts will almost need to sacrifice efficiency for the extension. Ported boxes have MUUUUCH less distortion for high SPL applications on music vs sealed, for sure. Or atleast around tunning. [/QUOTE]
