Help with cheapo shop speakers

[nathank]

Question about some cheapo speakers I use in my shop. They are some old floor speakers that I want to build a new cabinet for, that will sit between the studs of the wall. The shop wall isn't like a house wall, so I can't do in-walls on a plate, it has to be a full enclosure.

My question is about the old enclosure. It has some weird setup and a HUGE port in the back. Does this port seem excessive for what this is? The enclosures have a 10", 5".

With the new enclosures do I need to mock the old design, or go a different route. I know absolutely nothing about the drivers. My feeling is they are too cheap to even worry about much, but I want to make these sound as good as possible. Sealed be better than ported?
I have no specs on these speakers.
