sprkn_ranger Posted February 3, 2012 Report Share Posted February 3, 2012 Hey all, I'm wanting to learn a little bit about flaring a slot port. Im not wanting to know how to do it, cause my wood working skills are there,(I've done kerf bends before) my questions are more about how it works and what it takes to calculate the flare into the port design. I also read somewhere that if you flare the exit of the port then the other end of the port needs to be flared to match, is this correct? I'm new to building ported boxes (correctly anyways) and would like to learn, so If someone could point me in the right direction then I would be greatly thankful!

Hollowstylez Posted February 3, 2012 Report Share Posted February 3, 2012 Those are some good questions. I'd be interested in finding out as well. I first thought that kerfing was just for looks but as I read into port/vented designs i realized that every sqin determines the sound you will end up with. I'll be watchin this with you man. haha Link to comment Share on other sites More sharing options...

RAM_Designs Posted February 5, 2012 Report Share Posted February 5, 2012 Find a port radius that you can physically do and that gives you a nice and even number for 1/4 of it's circumference, since that is the length that will need to be added for the total length of the MDF that you need. I usually do a 3.5" radius since it requires 5.5" of length to do it, which is easy to add into the measurements...easy for me and easy for the customer.

sprkn_ranger Posted February 5, 2012 Author Report Share Posted February 5, 2012 Thanks for the reply ram, I do understand that, but what I'm looking for is more so how to calculate tuning with a flared port. Or does the effective port length end where the kerf'd radius begins? if that makes sense.

I've heard from somewhere that you just measure the straight part. I forget who told me that. Link to comment Share on other sites More sharing options...
