for a little extra money and work is it worth it? how much louder does it actually get

probably on average 10-15% more output over a sealed box.

It is worth it. Going from sealed to ported is like night and day. The output is far greater ported. And a sheet of MDF still costs the same, no matter what you do with it...

generally it is more difficult to build a properly ported box than it is to build a sealed one. and an installer will charge you up the *** for that.

a noticable difference by ear is 3dbs. 10 is asking a lot.

No, In most cases a 3-4 decible gain is achieved when switching. And as mentioned it is near double the output to your ear.

I hope this guy is not talking about prefabbed.

With the statment of extra work, I was hoping he would do it himself:)

3dB is actually alot when talking about decibels. The difference between a handsaw(not electric) and a farm tractor is only 3-5 dB

this is kind of a general statement but anyway, if your systems output is maximized, to get a 3db gain you would have to double your cone area and double your wattage. so just for an example, if you have one 12" and 500 watts, you would need another matching 12" and 1000 watts total.

remember, that was just to show him how much of a difference 3dbs is.

so according bri, you will be SAVING money if you want the same output.

no, you can optimize the single woofer setup without paying for another woofer and another amp.

but you will never with a single woofer acheive the same output of dual woofers of the same caliber with more power and proper encolsure, never.

I would say yes, but it also depends on what sub you buy. Some like to be sealed some like to be ported. For example, a w7 sealed sound like crap to me, but thats just me. ;)

Increasing the enclosure efficiency also helps when you're reaching the upper limits of a driver's rated power level...just because you can send that woofer an extra 300-400 watts and not have it thermally self-destruct doesn't mean you're getting a lot of benefit. Power compression will set in.

It's totally dependent on the install, especially in car audio, where you can run into cancellation a lot easier with more drivers ...

very true. i have heard two 12"s kill eight 10"s before.
