The real way to elbow your ports...

[IDSkoT 5,000+ posts]

Here's a visual aid for you guys. The elbow part I put down 3.5" (The width of the port) to ease the transition. If you have any questions, ask. The part on the inside of the port is needed for structural integrity. What I would do when cutting the inside port walls, I'd under cut just a bit so there's excess, and sand it all down nice and smooth. The build log will come soon for this box (hopefully.) It's for a member on this forum, he can tune in if he wants.

Never said I was. I just see a lot of people throwing in a 45 deg elbow and expecting it to come out fine... and some people just need a visual aid to understand how it's supposed to be done.

Hmm. Where did you learn this??

Haha! From the master himself!

Do you make the beginning of the outside angle = to the width of the port? I.E. The beginning of the angle starts 3.5" from the back of the port wall. Would that be a good way of rationalizing where to start the angle from?

I'm going to kerf the elbow on my next box //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

define "come out fine".... i've never used this method and with the success i have had without it, i don't plan on making more 45s to do it the "real way".

show me proof that it makes one bit of difference in performance and i might care...

 

[Pop da Hatch 10+ year member]

yeah it really makes no difference either way.

Measure corner to corner in the elbow of your port. The measurement will be longer than the width of your port. This will mean your tuning is different, as you will have a different port area than you orginally planned for. Sure, it is negelible in most cases. As long as you realize that it does in fact change it.

Edit: Doing it this way (as IDSkoT mentioned) keeps the port the same width, and the tuning stays the way it was planned.

Unless you are shooting for extra .01 - .03 deebeez, then I dont see it necessary for any 45s at all. but continue on............

 

[grassroots 10+ year member]

hm, come to think of it.... i think IDskot designed a box for me about a year ago for a 18 with interchangeable ports...

his designs did not have this new found method of port design...

i want a refund

Like I said, in most cases it is absolutely negligible, but when someone requests a certain tuning freq, I like to stay as close as possible. Not to mention it looks teh *** //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I'm not saying my process is any better or worse than anyone else's. By theory, it makes perfect sense.

anyone know if the port will be too big for the sx 12 ?
