4th order vs vented wall

[Trevor28139 10+ year member]

i have a 2001 expedition with:

2 DD 3515 CF

1 DD M3A

currently have a vented box subs firing up vent back.

going to do a rebuild this weekend and trying to decide between:

A fourth order with subs firing up into vented chamber with vented chamber firing forward, everything walled off behind the back seat.

A vented enclosure subs firing forward vent firing forward everything walled off.

my thought process is that if i wall off the space behind the back seat it reduces the amount of space to pressurize.

my main focus is daily listening but would like to see a nice number on the meter as well.

I dont think that the dd's are suited for a 4th, but im not too sure..I think you should try a 6th order //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

i thought 6th orders were really hard on subs?

Not if designed correctly, just like any other box. I agree, 6th order over 4th.

I agree too. with DD's you gonna wanna go with a 6th or ported.

A 6th would be a fun build, but a 4th will work as well. If you are able to design/build it yourself try em both. The baffles for sealing it off should be the same for both options.
