Exclusive Speaker Technologies

Four-speaker I-Sonic Technology

I-Sonic Entertainment System

Four-speaker I-Sonic technology delivers a room-filling, stereo all-around soundstage 360º around the entertainment system. You will hear big life-like sound everywhere in the room, even if you are to the side or behind the unit.

Patented PowerPort® Bass Technology

I-Sonic Entertainment System

PowerPort venting technology belts out the kind of rich powerful bass you'd expect from much larger stereo speakers. Bass ports redirect the sound created by the back of the speaker cone into the room.

Digital Signal Processing

We've harnessed the incredible data processing power of the latest chip technology to bring you superior sound.

Bass and Treble Controls

No matter how hard we've worked to perfect I-Sonic's sound, there may be times when you'll want to adjust the sound to suit your personal taste or to compensate for sonic flaws in program material.
