would going from sealed to ported w7 take advantage of it's spl capabilities?
sorry about making another w7 post 
but i'm interested in putting my 12w7 from a sealed to a ported box. i have heard ported boxes tend to be louder, and give deeper bass. anyway, how much louder could i expect the bass to be with a ported box?

Ported boxes usually give you 200% more throw from the subwoofer and about 40% less excursion. Also ported boxes give you GREAT low end extension.
The great thing about a ported box is that you can tune it to alot of different Hz giving it different capabilities. If you want purely SPL you should tune high (40Hz) and if you want a lil more SQ then tune low 30's (30hz-33hz).
Personally with a W7 I'd go with a 1.75-2.25 ported box tuned to about 30-33 Hz. It'll get DEEP...LOW...and loud =] and sound AMAZING while doing it. Though remember that with a ported enclosure it is vital to have a SSF (Sub sonic filter) or else your pretty much destroying the life expectancy of your subwoofer. Set the SSF to about 25-28hz and your laughin =]
Note: Ported > Sealed IMO

Ummm...you sure about that....
How about you do us all a favor and explain the technical term of "throw" that you just invented. While you are at it, let me know where in the sky you found 200%, and at the same time tell me what changed about the subwoofer that caused it to loose that random 40% of excursion along the way.
If people really lost 40% excursion going ported.....why would the SPL people go ported....doesn't make sense does it. Oh wait, I forgot about that 200% increase in "throw"

Not really vital depending on how careful/smart you are, and where you tune. I had my IDQ12 tuned to 28Hz and ran it all day long with no SSF and it survived just fine. You just have to be very careful with the kinds of music you play, and at what volume. The system will lose compliance dramatically near the tuning frequency.
So while a SSF is recommended, I wouldn't go so far as to call it vital. You will only hurt the sub if you start playing music at high volumes with audio information below your tuning frequency.

That all depends on the woofer, but generally, most people will be willing to compromise some aspects of the system for the increased output.

SSF should be set one half octave below tuning frequency. That would be 23 for 30hz tuning, and 25 for 33 hz tuning. That allows you to make use of some bass below tuning before the cone loses control.
If you are tuning to the low 30's or below, you can get by without it though. Unless you listen to bass cd's
I am not going to comment on the rest of that post

I'd suggest you do two things...
1. be able to explain what you are talking about if you want to be credible
2. quit taking technical advice from sounddomain.com

Everyone's got to start somewhere...too bad it's troll/scammer town now. It's still a good place for clasifieds and the Image Dynamics section.
