ahh the kerf for box is only kerfed at the exit.. problem??

The air goes both ways, so you really need it flared on both sides to make much of a difference

fritosaregood honostly what do you think about the kerf on my box? should move some air?

i just looked at the pic, it doesnt look like the kerf it tangent to the port, but more like just 2 angled pieces, i would have also made it smaller

why make it smaller?

Steve I don't know why but everytime I see your new paint I want a Dr. Pepper...... is this normal?

heres an analogy for you. running a high power stereo without a fuse is like having unprotected sex with that hot chick at the bar with the sketchy sexual history. Sure you may be fine and nothing happens but that one time something does happen you're fucked.

i dont want woofer broke like bass sound clip clip and voice coil overheat

it looks like the radius is more than twice the port width,

i just never go bigger than the port width

i just thought doing that would help move more air lol... do you think it might cause a problem..?

Lol I think you worry too much, just wait till you get it up and playing then you will know if it sounds good.

i was thinking leave the 12 sitting in the box in the hole and duck tape from the bottom of the sub to the bottom of the baffle so the sub doesnt free air. would that work?

pretty much. but you need to flare both the entrance and exit of the port, and also add one radius of your kerf to the port length. so a 14 inch long regular port would now have to be a 17" long port if you put a 3" radius kerf on each end

basically if i where to think about what you said basically make it look like a candy cane. because ive wanted to try and do this but wasnt sure which direction to go as well.

It depends on what you glass. when i do it i just flare the kerf since it is too weak without it due to all the wood cut out
