I looked for small speakers compatible with an amp designed to broadcast music from my computer. I fell back, for the first time, a repackaged product by Amazon featuring an unbeatable price. These speakers are in very good condition even if one of them has some very visible marks indicating a wall mounting. No complaints after connection, the sound is correct and no change is lamented in relation to a used equipment. The only observation is that the necessary wall mounting ring is broken (perhaps because of the return) which prevents a suspended use. It must be possible to get a spare part replacement from Amazon or JBL if any, (to see). This is the second pair of JBL Control One that I buy and I'm not disappointed. The first is used as rear speakers in a home theater amp Yamaha RXV 473, in addition to a Bose Acoustimass old system of 30 who has lost nothing in quality !!! . These are for my Mac desktop and are sufficient to sound to a room of 10 m2. SMSL connected behind an amp 2 * 50 W, the sound is a bit metallic and deserves, for the most demanding, a small subwoofer. However we will wait lapping required amp / speaker to provide a more objective judgment. Moreover it is possible to adapt a better listening experience through the iTunes equalizer. I am very satisfied with my purchase, both in the repackaged product Amazon as speakers themselves.
