I once assembled a 'frankenstein' 122 from an old -60's, plywood-shelved RV
cabinet ( with RV amp/speakers removed, and RV speaker ports covered up of
course :) "Frankie" was paired-up occasionally with my '70's 122 with
particle board-type shelves.

'Frankie' (RV cab) would blow away the 'newer' stock 122 every time in terms
of sweetness of tone and a fatter bass. These cabinets have a shorter mid
section because the horn shelf is lower than the standard 122 cab, in order
to accomodate the RV amp ( not to be confused with the 122 power amp :).

So whether it was the size/shape of the cab or the plywood shelves,
.......( or all of the above *o* )........ these differences were quite
ear-opening for me....

Cheers/Rob........enjoying this thread
