My face melted when I saw the craftsmanship of these. So awesome...Mine looks like Homer Simpson built it, but it was fun and I learned a lot about what not to do next time. I built a sealed, next I am building a ported to see the difference when using the same driver.
Just go creative with a CAD software and find a buddy with a CNC
I never accounted for the lost volume with the big vents but they turned out well either way. Lining the walls adds some extra volume seen by the driver.
Buy a measurement equipment there are well known kits for decent money that are simple to use and very useful when getting the tuning right.
Software like WinISD will ball park it quite good but a lot of things can go side ways with real cabinet volume, vent diameter, lengths and lining.
Eminence also share some recommendations in the pdf above that would be the safest simplest choice, large vented.
Hello Vin, I am a huge fan of your builds. I was wondering if you would be able to let me know how long each 4” PVC port is on this build. I went over the build numerous times and can’t seem to find that information. I am not good with computers so I don’t use Winisd or such. I have a similar build on the go and it would save a lot of trial and error to get the tuning right.
Thanks for your time
