Does anyone have DETAILED dimensions of the port that is on the early '90's PSB Stratus Gold as well as the mid-'90's PSB Stratus Goldi speakers? I have an interest in modding the earlier model to the latter model. I have not verified (yet) whether internal cabinet volume had been changed between the two. Any related info would be greatly appreciated.
I have litle info on the drivers. Both the Gold and Goldi had a 10" (250mm) doped paper-cone woofer with a 54 ounce magnet, and the tweeter was a Vifa D25AG-07. I believe the port on the Goldi is 4" in diameter, and of the Gold 3" diameter.
Still searching for more port specific and cabinet volume information.

That Goldi figure is a PSB spec (in their archive literature). I've since taken published overall outside dimensions, subtracted 1" for all nominal wall thicknesses, and arrived at:
Goldi internal volume 3.57 cu ft
Gold internal volume 3.61 cu ft
Should I acquire the Gold and fab a 4" internal diameter port with significant flare (on both ends), I'd then need to, after enlargening the cabinet opening as appropriate, do some iterations of port length. I have a UMIK-1 microphone and REW experience, though exactly how I'd assess the change(s) is a topic for the future.
