Polk Audio's newest in-wall speakers were on display for all CEDIAnistas to see. In a separate part of the booth, Polk demonstrated the company's - and the world's - first THX Ultra2 Certified in-ceiling loudspeaker, the RTS100, along with the RTS105 in-wall. On static display were two THX Ultra2 Certified hopefuls from Polk: a dipole in-wall and an in-wall center channel.
