Need opinions on modifying a built in port - that I built in ...

[Bmsluite]

Long story short: I screwed up the length of this port royally

It utilizes a Tang Band W5 for the low end

Anyways....take a look at the screenshots of the model. The one that looks like a proper rectangular 3 way cabinet is how it looks now. Yes, I already built this.

What I want to do is modify it by cutting out a portion of the port.
My questions is whether this crazy outlet shape will still function as port even with the one face still remaining in place. Thoughts?

There is no difference in the port outlet shape or cross sectional area "before and after", shortening the port will simply raise the Fb, and the pipe resonance frequencies.

That said, looks like a huge port cross sectional area for a 60Hz Fs driver with only 3mm Xmax.

OK, good. I wasn't sure the effect a plate would have right next the port.

9.25 mm xmax. It hits.

Right now I have a huge rise at 20 Hz for the port but then a giant dip at 40. Can't hear it. Can definitely measure it

I redid my calculations and found out I screwed up and it needs to be 21" shorter to give me the boost in the frequency range that I want

~Ts parameters for that driver leave a lot to be desired.

i put them in a 28 hz tapered qw tube for fun regardless
