There were a lot of prefab "one size fits all" cabinets on the market in the 50s. Seems people would buy drivers and upgrade when they could, etc.

The problem is one size (port) does not fit all!!

I wish there were options for ready made cabs like this today. Most of the premade cabs are under 1 cu ft, which doesn't do people like me (many of us here) much good.
