I'm looking for a small full-range speaker cabinet with a tweeter for jazz guitar and amplified nylon-string guitar. My budget is very limited--$300 or less. Used gear is always an option (I don't buy amps new, as a rule). I will be pushing it with my Acoustic Image Clarus head. Any of the BG/guitar doublers here have any recommendations? The Acoustic Image Contra extension cabs look really awesome but I just don't have the money.
