Finally built my bandpass today. Its almost done. Its 6.00 Ft^3 tuned to 32 Hz, built according to Death By bass' calculations. Made my ports out of some 4" PVC glued it up today so tommorow i should be all set.
Camera phone pics so there ******.

Well I finished it up today, not impressed to say the least. I think im gonna tear it apart and salvage what I can. Im either gonna build a sealed or ported box. What do you guys think would be better for two 12 W/0's? Oh well I guess thats how you learn.

how did it sound ouput wise
and did it hit the lows decent
did it do anything besides waste your time

heres a tip
if u plan on over powering your subs u should have made the sealed chambers smaller

Maybe you were expecting too much from those drivers? Have you used them previously?

And the type of enclosure of course depends on what kind of results you are looking for. Is this enclosure not loud enough? SQ ****? Whats the problem?

the box was supposed to be:

100 litres sealed, 50 litres tuned to 60Hz?

which, I'm not sure if yours is...

which is the tuned section?
60hz is suppose to sound good? :laugh:

when tuning a bandpass box u suppose to tune the box in the middle of the bandwidth
so 60hz is fine
his bndwidth allows him to still go low not as low as a bandpass tuned to 40hz but low enough to play late night tip and have flexing

W0s used to be known as one of the best subs for a bandpass application.

SQ wise it sounded good. I just expected it to be louder. No im not blaming it on you Death by Bass, but i thought you told me it was tuned to 32 Hz? Its doesnt sound bad, but for the amount of space it takes up its just not worth it. I think im just gonna buld a sealed box.

w0's sound very very clean in a sealed box and ok output :)

saywhat?
04-04-2006, 08:36 AM
6 cubes? lmao thats a little much for a bandpass for those dinky little subs. me and 80 were lookin at like 4 cubes TOTAL for my SE's.

saywhat?

it has a -3dB point of 32Hz (in theory) meaning it should play very well down to 30hz...

it should be as loud as a ported box, but sound better :)


looks like it has crap output until like 60 hz.

JL's arent supposed to be brain rattling, expecially those. you got the wrong subs to get loud.

why would you have it peaking at 80? :rolleyes:

Its not that I want them to be brain rattling, there just not that loud. The size of the box is to big for what im getting out of it.

u needed to make your ported chamber bigger and your sealed chambers smaller......if u did this u would have had more output and u would be able to tune lower than 60hz

Then change the size of the box, or change the equip.
