I wanna build a normal dual enclosure for two 12"s.. but I was thinkin of building the box one side sealed and the other side vented.. its gonna go in my chevy cavalier trunk.. j/w! how would that sound... the subs are 2 12" L7's and thier gonna get thier RMS wattage at 1 ohm

would sound like mad cancellation.

if thats what you want, why not try a bandpass enclosure?

or, do what the post above says and pick one or the other (hint, this is your best bet)

people always talk about cancellation but the truth of the matter is you cant say if this will actually happen or not until you try it. Build it and if you like it keep it, if you dont build another box

i have a feeling if it's built right then the sub that is ported will be "louder" therefore causing cancellation. But i could be totally wrong tho

i feel very confident in saying that the output and results from this type enclosure would be much less desirable than an either sealed or ported enclosure.

eh true ill stick with a vented box.... is thier a difference between a dual 12" enclosure with the two vents on the out side of the subs(not in the middle) compared to a normal box you would see with the vent in the middle with a divider in between like this... for 2 12" L7's

middle- http://www.tycromedia.com/images/Custom%20Dual%20L5%20L7%20Ported%20Sub%20Box%20(12-inch).jpg

Dude I think you should do it. Just have each sub running off of another amp and set the crossovers and sub-sonic to where each sub only plays a certain frequency. Who knows it might work and sound really good. What kind of car is it?

what the hell is high bass?

Will sound like ****, it will sound like two completely different subs playing, which in this case is no good. If you did enough tuning through trial and error and with lots of processing you could make them compliment each other nicely. But i dont think anyone on here has the knowledge or resoures to do that well.

or just build the box to be ported and wire up an actuator inside to close up the port. then flip a switch and it could be ported or sealed..

I'm trying to envision that and I can't picture it. Bandpass?

I'm sure that someone before you has tried it and it failed. Therefore, nobody uses it today.

dont do it.... a sub does not have to be sealed to sound good. Unless your going to be a super SQ master the just do ported. You wont even know what you missing

Depending on where he mounts the woofers will depict whether its a bandpass enclosure or not..

what the hell is high bass?

bass above 80 hz

James Bang

bass above 80 hz

oh...

hmmm..

well, how would a sealed box coupled with a ported box yield a peak in 80hz+?

if he had his crossover high it would.

James Bang

he just needs a good pair of correctly installed midbass speakers.

That's not the subwoofer's job, that's midbass at that point.

Why even have a LPF if you set it at 80 hertz
