ok i bought ported box for my l7's from the flea market, i had no idea that the box played such a critical role when it comes to tuning. im trying to tune my amp, and i just found out that in order to tune the subsonic filter u have to know what your box is set to.

is there any way i can figure this out?

question 2.

then what do i set my subsonic filter to?

looks like your going to have to do some measurements.

( sigh. )

Measure the thickness of the wood;

Measure the outside of the box; width, height, length.

Measure the length and width of the inside of all the parts that make up the port.

( I'm assuming it's a slotport? )

ht. 14"

width. 32"

length. 14"

there 2 portsin the middle of the box approx 12.5 tall and 2 wide, it goes all the way to the back

also dont know if this goes without saying but the subs sealed off from each other from the middle wall in between the two ports

and the wood looks like its 3/4"
