in my opinion, this speaker is the best value for the money in category of 10" guitar speakers, very good "all-rounder" for home/small studio use. I wouldn't go below 10" size, because 8" size guitar speakers can not provide sound that is "big" and good enough. on the other hand, 12" is to big for home use.
VT-junior speaker sound similar to his big brother V-Type, not exactly the same, but close enough.
