whitetrash84 Posted July 20, 2012 Report Posted July 20, 2012 Just wondering, with a slot port running down the middle and the branching off left and right at the back, does the width stay the same or is it 1/2 the width? I've always done 1/2 the width and now I'm not sure. So in my sketch-up the port shrinks to 3 1/8" at the back, or does it stay 6 1/4 on both sides: Quote
bassface Posted July 20, 2012 Report Posted July 20, 2012 Yeah you got it right half width. I have seen many of these designs with a v diverter right in the middle though. Quote
whitetrash84 Posted July 20, 2012 Author Report Posted July 20, 2012 (edited) Yeah I was going to try a "v" and see if it does anything Edited July 20, 2012 by whitetrash84 Quote
bkolfo4 Posted July 20, 2012 Report Posted July 20, 2012 Input a V on the back wall in the middle when I can. Just make sure the port is not restricted to less than 1/2 width at the corner. You can also cut the end of the port walls at a 45 to take away the point where it turns.

412 CVX Posted July 20, 2012 Report Posted July 20, 2012 You got it right. you don't need to add the V thing, but it does help. Quote Just say no to Ground Pounder Customs.

whitetrash84 Posted July 21, 2012 Author Report Posted July 21, 2012 Yeah just not sure about a kerf with a 2" radius. Might be kind of tight. Quote
sprkn_ranger Posted July 21, 2012 Report Posted July 21, 2012 Yeah just not sure about a kerf with a 2" radius. Might be kind of tight. I did my kerf with a 2" radius. It was a little tight but it came out fine. Check out my build log in my sig for pictures.
