sue me, its a ford.
argh's have no lows sealed, even with polyfill.
GO PORTED TUNED LOW AND SHUT THE **** UP ALREADY

I have ran them both and I can assure you there is nothing incorrect about my statement.Not true. But if someone has ran sealed and is happy with it, they may not port it. So its hard to find someone who has run both and isnt biased.
I would run ported tuned to 27hz for a SQ set up. The point to running sealed is a flatter response, but I feel a sealed enclosure can sometimes puts added strain on the mechanical aspect of the subwoofer. If I can achieve a flat response running a low tuned ported box, with less power to get the same output, why not?
I never said it could be achieved. But in some situations it is more difficult to get a 1 cu ft box tunned to 27hz. This is where sealed comes in. I for one do not like sealed boxes. They sound nice, but I always feel they roll off too quickly. Maybe its just the sealed boxes I have ran. //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gifI have ran them both and I can assure you there is nothing incorrect about my statement.
How can sealed have flatter response if you can get the same thing with ported?
Sealed boxes usually do roll off quicker. A low tuned ported box will often give you a flatter response, that is why I was questioning your blanket statement that sealed boxes have flatter frequency response.I never said it could be achieved.

Sorry, I should have explained myself better. I ment above the roll off. A ported box often has a peak (as in the 30-33hz tuning mentioned) but I was trying to make the point a low tuned ported box would do better then a sealed box in a flat response.

You are right though, it is usually quite difficult to tune low in small enclosures.
Again all he is saying is the ported box will not have as flat of a response curve as the sealed box.what he told me in that was the type rs in a ported box even built to specs will have under damping at lower frequencies and get "flabby" sounding:
"But the key thing to realize here, and what the people who are recommending you use a ported enclosure are omitting in their advice, is that this is really a sealed box woofer. Look how bloated the low-end becomes once room gain is added in. And more importantly, look at how the phase response and especially the group delay tear up at low frequencies. This is indicating that the speaker will be underdampened at low frequencies in a ported box, even one designed as expertly as possible. The low-frequency output will definitely increase, but it will be out of porportion with the output at higher frequencies, and the bass will be loose and flabby"
