wall ?

[mcbuggin 10+ year member]

I've never built a wall but plan on trying it this winter I have a design in mind but was wondering about kerfing the back wal and if it would help spl wise as opposed to just keeping it flat? Any ideas would be nice

Might help might not.Just have to do it and see.

since I don't have a mic avaliable to me would it hurt me in the lanes or just no way of telling without testing. I just figured that if the subs were on the passanger side and the port on the drivers side then it would help the air flow better out the port makeing it more efficient. Sorry for my bad spelling but i can only spell a lil better than seth

ur best bet is to go with a normal square back wall and do a temp kerf and test it and see if it helps or hurts. try a simple 45 in the mix too to see how it helps or hurts.

No need to apologize, I cant spell either lol

Do a temp setup once the wall is built. You can experiment with 45's in the corners. If your in love with the idea it would be a lot easier to round the corners out with bondo or fiberglass, so you dont lose any rigidity.

wish i had a mic and then that's what i'd do. So since i don't has anyone tried both and what were the results? this wall will contain 4 HDc3 15's and be powered by 2 IA40.1 amps if I can find another one after the first of the year 16cf net and 250sq" of port tuned to 40 hz. just an fyi

lol what do people not understand about there is too many variables when it comes to walls and boxes. everything is different. if it was easy to know the best way everyone would have the same exact design.

u will not know the best way unless u get it on a meter and try them out urself.

Its best to build a flat wall and change the interior shape and test.

In my tests and others tests, curved back walls hurt SPL. The reason is that waves are being compressed to a focal point at the center of the radius, this increases air velocity which is bad for SPL, then low pressure eddys are created just outside the center of the radius causing turbulence.

Guys in Europe building walls with 2 subs have been building straight cubes in small cars and have been doing 167s and 168s.

With larger vehicles such as Astro vans, you need angles in the corners to work properly.
