Would this box be alright? I'm pretty sure it is, just getting some opinion before I build it. Dimensions are 31.75X11.25x10.5 with ~1.4 ft^3 of volume and 30.5 inches of port tuned to 33 hz.

It's better to run the port straight against the back wall rather than zig zag it.

Well I don't have anything to kurf cut the mdf and bend it if I do it that way. Is it really that bad to run it this way?

You don't need to kerf cut anything. Just join two pieces in an L shape.

I had my 2-10" Type Rs in a 2.15 cu ft box (after displacement) tuned to 35 hz...I thought it needed a bit more of the lowend stuff

it got pretty loud though

congrats on your sub...good choice ;)

Alright man thanks I'll just redo it with the L.
Thanks again slammed so you think 1.4 ft^3 would be too much for 1 10"?

I'm looking for SQl and at the moment I only have 280 but I'm looking to add a little more in the future

1.4 before sub displacement?

if so, I think you will be fine. If you want lower bass and want the sub to be more efficient you can make the box bigger...but it will probably get a bit boomy.

Hmmm. Since it is being underpowered.. Wouldn't you want the box larger? Decreases power handling but increases output. Right?

In theory, yes... but the sound can also change slightly, in favor of a more boomy sound.

Hello all,
Can anyone help me with a box enclosure design. I bought one sax100.2 and one SD-1 v.2 on sale from Jacob, he recomended these specification for the enclosure

1.8 - 2ft^3 tuned to 30 - 35 Hz

but I wouldn't know where to start. This box will be going into a Mitsubishi Lancer
I didn't want to hijack the op's thread but thought it was the closest to my question.

thanks.

I am really debating on getting some type R's or Diamond D3's, with your experiance would you say its more of a SQ sub or SPL? I am trying to find a good in between, maybe more on the SQ side, my mtx 9500's are just too much for daily driver.
