I think I’m confused as to why a person would use a big tapped horn subwoofer for Metallica? Especially with a driver that’s likely to ring (high Qes) ?
there’s ringing and group delay all over in the 65-90 hz region in your box design, and it uses a driver that’s prone to it as well?
Poly fil doesn’t do anything at those frequencies, you might as well just clog up the vent mouth/ exit with it instead and make it a sealed box.
I dunno…. Nobody uses an Ultimax in a devestator either (the resulting high Q resonace spike sucks) 🤷🏼

I’m Not sure anyone would tolerate this much delay? As a result, nobody is using tapped horns or things that require radical filters typically ? Except for the blip on the radar like 2 decades ago in diy cause it was new and exciting at first?
(I dunno 🤷🏼)
