, thx for the tip
That was easy. No really. I had cut the port like 3 times. 1st time only 2 inches then a couple more and then finally to 11" as LTD02 recommended.
Thank you for this ! Really appreciate the efforts into explaining the different steps.
I am actually planning to build a similar setup. I have built Mini Marties before, but currently have the two UM18's in 4 c.f. sealed boxes (PE flat-packs). I was planning to build two Full Marties now or possibly even bigger boxes with similar ports like yours, move the UM18s in there for low end duty, and add two PA460 in the sealed boxes that the UM18 were using before.
I actually just read about the Precision ports available on PE the other day, and was thinking to use those instead of the slot port as in the original Marties. Nice to see someone else also using these.
If you don't mind sharing, how did you cut the ports to length? Are those PVC ? I watched a video on YouTube I believe saying he found a miter saw best for this, in order to prevent kick backs or other problems. I only have a circular saw in my disposal, not sure how good of a job that would do.
Also how do these get attached to the box, I assume you just pre-drill through the screw holes and use screws to fasten and seal with some silicone from inside ?
Not sure if maybe applying some gasket type under the external flare (similar to how one would use for the drivers) is also a good idea ?
Thanks again ! Those look amazing and I bet the system sounds amazing too.
