Small speakers...big sound??

Hello

I'm looking for some suggestions please!! I'm running some vintage Goodmans Triaxioms which I really love...the sound is big, full, definitely not the last word in detail but I can sit and listen to them all day with zero ear fatigue :)

Now question...can I get the same sound from a bookshelf?? I do not like anything bright sounding but I want a full sound that can fill my room.

Unfortunately I might have to part with these beauties. Locally I can audition nothing so all I am going on is internet reviews. Here are some that "may" fit the bill:

Era D4 or D5
Usher 520
Von Schweickert VR1
Gersman X-1
Mordaunt Short Carnival 2
Epos ELS3
Others??

What am I missing and can anyone make suggeestions that would work for me??

Thanks kindly!!!
