Polk's engineering breakthrough changes the rules for small system performance. Conventional table-top systems "beam" the sound straight towards the listener, even those with two speakers. At best, these designs can create a stereo soundfield for someone seated directly facing the unit. It's not at all satisfying for any other listeners in the room.

Only Polk's exclusive, patent-pending I-Sonic design lets everyone in the room enjoy the rich sound. The I-Sonic stereo soundfield is projected all around. No matter where you are in the room, you'll get the full I-Sonic experience with either the I-Sonic ES or the I-Sonic ES2.
