I-Sonic® Speaker Technology

How we get room filling sound from I-Sonic

---

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. It's even worse if you're behind the unit.

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.

Couple this with patented PowerPort Technology and advanced Digital Signal Processing, I-Sonic and I-Sonic ES2 sounds huge, from anywhere in the room!

Christopher Jones from Playback Magazine commented “…the ES2 came as a revelation: when I walked between rooms, I heard nearly the exact same sound quality wherever I stood.”
