I've been using a ~$200 10" powered speaker with Roland synth modules and a Yamaha WX7 for a couple years to emulate brass, winds, and strings. Clean sound, portability, and small size are all a must. This speaker was "ok," but in some situations, sounded slightly ragged. I need another speaker and decided to go upscale with the EON 610, knowing it was about 6lb and a couple inches larger, all around. Compared to my old 10" speaker, the JBL seems taller, wider, and deeper than the dimensional differences would suggest -- it's almost as large as some economy 12" models. Where the old box could be planted unobtrusively in front of a music stand or to the side of my chair, the JBL's size might be an issue. Sound-wise, the EON 610 is LOUD, very clean (like listening with a pair of headphones), tight, and transparent. Even with the gain set for mic input, it is extremely quiet. Instruments are smoother and more realistic, although not dramatically. Extended A-B comparison gave the JBL the edge, which, at near twice the cost and twice the power, isn't surprising. Dual channel mixer and selectable EQ curves are nice touches. It's definitely worth the extra $$$, size, and weight. The negatives -- yes there are a few. No manual in the box (you need to download it). The Android Bluetooth app requires Android 4.4 or better (why not 4.0?). Unless you have a device with Kit Kat, you are out of luck (or more $$$) to use the heavily advertised Bluetooth feature to tweak EQ and gain with your smart phone or tablet. Various JBL info states all the EON 600 series boxes have a handle on each side, but the 610 has side handles only. Lastly (and this is an observation, not a gripe), the 610 appears not to have the fancy woofer wave guide. Regardless, the coverage is still wider than the 12" or 15" model. In all, the EON 610 might be a little large for a tight pit orchestra, but can probably hold its own on stage for many applications where the smaller box won't cut it. Great performance extracts a small penalty in weight and size. Price gets JBL sound and quality, and a sense of confidence that goes with them. It's a keeper.
