when they discovered they couldn't get at the inside of the cab to install speakers if they were sealed. several prototypes of sealed rear-loaded cabs were made but nobody could ever figure out that dilemma well enough to proceed to market.Aren't we missing something more obvious? I mean an old-time "rear-loaded" cab with a modern ampeg logo? Even if it was an old ampeg cab did they even use a logo like that on them then? When did everyone start front-loading cabs?
i know, i'm being a wisenheimer today...sorry...
