Not long ago, Gene offered me the opportunity to review a first production of a new loudspeaker system by AV123. I jumped at the opportunity as I’d seen their name pop up in a number of online forums and read the reviews of some of their other products. I was curious to see what the chatter was all about. Soon thereafter, The Onix x-ls, a 2-way, vented cabinet system, arrived.
