Well, first I have to admit my preference for old Celestions from late 60´s ´ early 70´s ;
but Goodman speakers were considered upgrade speakers in several British amps in the 60´s and from high quality, (btw, they made all kinds of speakers,) and so long as they were intended for guitar/instruments, they are defenitely not bad, also the ceramic magnet speakers from the 70´s in the 20-50 watt range, sounds good to me.
Generally I don´t like front loaded cabs,

(like AOR 4x12 or any other manufacturer).
Rear loaded cabinets are warmer, have a bigger bottom and low mids,
of course in a band context you won't hear a difference, it's subtile.
Front loading gives you more of the speakers sound and rear loading gives you more of the cabs sound.
A newer Laney GS 4X12 might work and would be an "OK cab", but TOO MODERNISTIC.

I wouldn´t go this road.
And furthermore, of course soundwise 500 miles apart from a good vintage Speaker. This is not a real surprise, cause what you pay is what you get and a good vintage speaker all alone, 60´s / early 70´s Celestions for example, each speaker would cost $ 200 - $ 300 (in good condition).
