Hi Scott: Quite a few years ago I owned the smaller Sona 31c. Impressive clean sound but only one channel input and no on board eq controls on my version. I switched to the Roland KC300's about 5 years ago, preferring them for the multi- channel input & onboard Eq control, and I personally liked the KC300 sound better too. As much as the weight itself, I feel that the shape & weight distribution (ergonomics) play a big part in how easy it is to transport. In addition to the smoother frequency response, this is the the reason I moved to the EV SX-A100's 9 months ago. The JBL Eons were another option I auditioned & considered, but for acoustic jazz standards , I find the EVs the best at providing the natural acoustic sound without the hyped (boomy) bass, which appears both you and I prefer. I was lucky because the store I auditioned at (and purchased from) had all of the above speakers available in their listening room so I was able to compare them side by side.
