PM me if you want to upgrade the 18 XCON route. i might have a deal for you.

Seems to me that sealed boxes handle low lows better. I might be wrong, but that's just what I've noticed.

Those low notes are put out by the excursion of the sub. A sealed box makes the pressure that the sub exerts force back onto itself, making it rebound faster and not allowing for that full excursion, unless you are using a very large sealed enclosure. ported lets the sub "breathe" so to speak and allows for more and deeper movement of the cone. (as far as my understanding goes)

Yeah, you lose a good bit of excursion, but I don't have really high power subs and I listen to a lot of different genre's of music so I was trying to keep the subs controlled by putting them in a sealed box. They do hit some pretty low lows though.

Generally a sealed box will handle notes below 25 hz better if the ported box is tuned to average in-car tuning frequency of around 32 hz. But a ported box generally rapes a sealed one from 30-50 hz.

As for excursion, you can definitely get full excursion in a sealed box. It all comes down to power. In a ported box it takes very little power under the tuning frequency to reach full excursion, whereas sealed boxes can handle more power that low.

Not really.

Not really to me or RickMorgan?

If I'm understanding your post, you would be correct in that sealed enclosures don't have the unloading issue that ported enclosures have.

Yeah, I've noticed that a lot of people I know from around here think my box is too small because my subs won't bottom out. Sooner or later, they'll listen to me about telling them to use the subsonic filter.
