This is for an 8" sub, its just a test box but a nice one at that.
0.6ft^3 is what were shooting for and a tunning of 35hz.

I would like to start off this build with a video of the design. Just messing around in c4d having some 3d rendering fun ;)

Ok had to squeeze it depth wise 2.5" and stretch its width. Im really getting the hang of the 3d program now.

I cant wait to see what it sounds like...
If you ever feel the need to upgrade, this box will handle a lot stronger 8" easily.

IF i had FG to strengthen that bend i would but im fresh out so ill just use a mdf/woodglue paste and if needed I have some bondo i can toss on top. Although i doubt bondo will add any structural strength. From what ive seen though, it should be fine after i glue it up.

how far apart did you cut the relief cuts for the kerf? going to try one this weekend.

how far apart did you cut the relief cuts for the kerf? going to try one this weekend.

at first they were 3/4" apart from eachother but that just didnt work so i did 1 in between each 3/4" cut.

I went over it a few times.


Instead of doing more cuts, try to do them spaced very evenly and depth is key.

Ever take a slice of mdf... a 1/8" thick peace.. it bends but past a certain point it snaps.

Well now take a slice that's maybe 5x thicker than paper.... It will almost bend in half without snapping. This is what you want to achieve.

Just make sure that its not so thin that when you pick it up it will break apart.

I recommend doing a test strip just to see how thin you can get and how flexible it will be. This was also a rather very tight turning kerf on a really small box. If you want more information there was a thread about it somewhere on the forums. Goodluck

So Its not all that bad for a 30$ ebay sub
Not sure how much power i was feeding it, it was running off my 4ch orion
It was reading 3ohms so it probably saw around 140 watts max

The video doesn't do justice of it really
Sounds nice for something so small but placement really has a huge effect. I messed around with placement and such and noticed increase in spl.


So Lets hear some comments, and most importantly, how does the box look:laugh: (http://imageshack.us/)

this mans work is outstanding:D the box came out beautifull. Now, I placed the box sub up port back in my hatch and it sound nice and pretty loud for an 8"(this is actually my first 8" sub)I couldnt be happpier. For a 30 bucks sub it does a great job.

is there like a certain amount of cuts that should be made?or just what ever it takes to curve the wood?

there should be no visible gaps in between the cuts on the backside of the kerfed piece...

can you elaborate?
thickness is 3/4"



and yes there were to many cuts.

at first i did 3/4" apart and it wouldn't bend enough so i thought more cuts was the answer.. which was false i just had to make them deeper and that worked just great.


Definitely learned on that and that's the reason this is a test box ;)

If i was on a really tight budget i wouldn't mind having it sit on my back seat for the time being =)
