Small but oh my!

The Barbetta SONA 31C Keyboard Combo Amplifier delivers 225W continuous RMS power from 2 - 8" woofers and a 5" horn tweeter -- and it weighs only 35 lbs. Like all Barbetta amps, the SONA 31C keeps it together on the low end, has bell-like clarity on the highest notes, and the middle notes sound absolutely fantastic. It features a modified Linkwitz-Reilly active line-level crossover specially tailored for the SONA 31C. Ported reflex cab with proportional damping is made of polyurethane bonded wood. The power section is a fully discrete, bipolar, class AB design with a slew rate of 70 volts per microsecond. Active level control. 3-band EQ. Barbetta built 5 input channels including an XLR mic input into the SONA 31C combo amp.
