Okay, what I meant was, if you had a sub that could handle....lets say 400Wrms in a sealed box; wouldn't it be as loud as a sub that could handle 200Wrms in a ported box (if both subs were rated at the same db sensitivity, and were the same size)????
But the 400W sub would sound better and tighter, and less "muddy". But would the 200W sub still sound deeper???
I'm thinking this 'cause you gain approx 3db with the ported box, but you'd also gain approx 3db with twice the power.
Point being (depending on the answer to my questions above) if one were to prefer a ported box because of it's ability to get louder, couldn't they just get a sub that handles twice the power, at the same sensitivity rating, and put it in a sealed box so they don't have to give up the SQ????
Just a thought...I'm kinda bored GRIN

I was thinking again.......it's probably easier to put a sub in a ported box to get 3 more db then it is to find a sub that can handle twice the power....
Like for what I have, (2 10" subs that handle 350wrms) I would need to find 2 10" subs that handle 700wrms each, with the same sensitivity rating.....probably kinda hard to find, and very expensive....

Just my take on it,,,not an expert but ok..lets say you have a lower end subwoofer with lets say.....500watts RMS in a sealed enclosure(lets just say your gonna hit 130dB) Now..you have the same exact 500watts RMS sub in a ported enclosure (133dB). The Ported will net +3db gain over the sealed as well as hitting low hertz well as you already.
Now take a higher end subwoofer with a higher RMS value...say 1000rms compared to the 500watts in a sealed enclosure. Since you gain +3dBs everytime you double the power that will set you at 133dBs. But even if you did double the power, your still not going to gain the ability to hit the low hertz 25-35 as you wouild with a ported enclosure.
Not only that, but doubling the power to net another +3dBs will cost you $$$$ in electrical upgrades which isnt a very intelligent way to go about it unless you have money to burn.
Im sure Chronos, Swez, or some of the other guys will have more input. Im going to be in the chat for about 20minutes to see if anyoen comes by

when ur talking about the ported hitting lower hertz? i thought that they are tuned to not play some of the lower sounds?like say tuned to 30 hertz? is it that i could be thinking of frequncy or someting?

Your correct, we tune ported enclosures to a certain frequency that we so desire. Anything below the Port Tuned Frequency needs to be filtered out using a subsonic filter.
You can tune a ported enclosure as low as 25Hz and not have to worry about using an SSF due to the fact that anything below about 20-25Hz is used in car audio (most people can only hear down to 25Hz Maaayybe).

ya rigth here if your ported box is tuned to lets say 35hz and you use a 12db per octave SSF to block out anything below 35 hz then your sub would still play slightly below the filter say down to 25 hz it would just get quiter every octave(10hz).. and PL is right you cant really ehar anything below 30hz 25-30hz is audible but barely and antyhing below 20hz simply cant hear it you can feel it and hear it rattling things but not any sound so to speak.
also to adress the main question you could find a sub twice a potent and get it just as loud as a ported sub but you would not gain the low end response a ported enclosure has.
