Sub enclosure question

[skirch56 10+ year member]

Hello,

I am planning to build my first ported enclosure. I use an online box calculator to tune the box. Here is my proposed drawing . . .

The program told me I needed a 19" port. I drew it like this, because to do a straight port the box would have to be a few inches taller, but I don't have room for it. This box is 6 inches deep from this view, the port is 5x1 and about 20" long as drawn.

The box is being built for 2 JL 6w3v3's. It has a volume of just over .5 cu ft, not including the port. It is tuned to 35 hertz. (Also this is lower than the manufacturer's recommendations of 38, is this ok?)

Does this still work as far as the port measurements I am supposed to have? If I didn't give enough info, let me know.

i highly suggest you use a program like google sketchup to make your designs, it will be much easier to understand and read.

I guess what my two questions are is

One, will there be any negative effect to sound quality between a straight port verses a port that zigzags back and forth, or even a L-port

And two, will I damage the subs by tuning lower than factory recommendations
