The PL-664 parallels design elements of the Olympica Nova Collection with the the leather embellishment around the tweeter and midrange. The magnetic edgeless square metal grille can be easily painted to blend in with the listening environment. Thanks to the swing out dogs fixing system, all Palladio speakers can be secured quickly and effectively to plasterboard.

The speaker is designed to cover multiple roles based on individual needs. It can be used as a front/side/surround channel in the vertical position or as a center channel if mounted horizontally. Two versions of the wooden panel are available to allow both arrangements by simply removing the four screws. Additionally, the PL-664 can be completed with the Premium Kit that includes the natural wood front mask, the string grille, and the paintable magnetic frame.
