Polk Audio has announced two new portable iPod audio systems—the MiDock10 and MiDock Studio. The MiDock10 ($180; shown) features two 3.25-inch full-range drivers in a black ported enclosure. It offers USB connectivity for syncing with iTunes, side-mounted handles, auxiliary input, and headphone jack. The MiDock10 can be operated on AC or battery power, comes with a credit-card sized remote, and fits all dockable iPods. The MiDock Studio ($TBA) is a slightly larger and differently styled iPod audio system being released in April. It features dual 3.25-inch high excursion drivers that are vented via a side-firing flared port. The MiDock Studio features a two-tone black grille/white body color scheme and also has handles, USB connectivity, and auxiliary input.
