I love the Barbetta Sona 41 series. I have the 41C with 2- 10" speakers and the bass is huge. And at under 40 lbs it is a better deal than the heavy Rolands. I use it for restaurants and smaller single gigs. When I do larger rooms or play with the band , I use EV sb122 passive subs and ZX1 satellites. Power amp in my rack. Or you can get sb2a powered subs from EV and eliminate the power amps. Thunderous bass and lightweight. My subs are only 36 lbs and the powered ones are only 3 or 4 more. The satellites are 16 lbs ea.
