A rather open question but... how they all compare? Do they sound very different between speaker configuration and size?
The Camaroon on the far left sounds like it looks: small. Very thin, tinny sound. With the lid on, it does fatten up a bit, but not enough. It actually has the most powerful amp of the bunch, but it is driving a very light speaker.
The Carona still sounds small, but is much better with a boost pedal in front of it. The speakers were from the center channel of an inexpensive home theater surround system. A functional little amp, but I wouldn't want to listen to it all day long. If you flap the lid open and closed while playing, you get a nice wah sound as a bonus.
The Rothchilde (Vox styling) and Cohiba (Cuban) amps actually sound very nice for their size! Much credit to the Jensen speakers in those. Surprisingly full, rich sound--not massively loud, of course. The Cuban amp has better bass response, possibly due to the slightly deeper cabinet, more solid baffle, or intact rear wall (I'm not an amp expert, so these are just my guesses).
