It is impossible for a lightweight, battery-powered portable speaker system to produce the same sound quality that a larger, high end plug-into-the-wall unit does. The laws of physics are too stacked against small, power-efficient speakers for that. But the On Tour portable speaker system from JBL comes remarkably close to breaking these laws. Newton himself would be amazed at the big sound that comes out of these little speakers. We are guessing that he’d also appreciate the On Tour’s design that includes a sliding cover and optional top clamp that can hold a portable game system (Newton being the sort of guy who surely would have had a Sony PSP).
What’s most remarkable about the On Tour system, though, is its low cost. At the current Amazon sale price of $50~60 there is absolutely no other speaker system that provides as much quality for as little money.
