More About the Chairs

Head speakers
There are two speakers (high frequency drivers) in the head rest portion of the seat back. Each speaker is angled approximately 30 degrees toward the listener.

Back speakers
Both spine speakers (mid frequency drivers) are contained in the same cabinet, although a divider separates it into two independent chambers, one for each speaker.

Seat speaker
BodySound refers to the low-frequency driver in the seat as a driver, not a speaker per se, since speakers typically consist of driver(s) contained within a cabinet or housing and the seat driver is not housed in a cabinet. Even so, it’s a speaker for practical purposes.

Arm speakers
For a 7.1 experience, arm speakers are optional. They must be connected manually to the amp’s external speaker connector.

The five- or seven-speaker array is powered with an in-chair 650-watt, seven-channel amplifier. DSPs provide independent channel control of volume, audio AC3 component mix and EQ shaping. The same goes for the automatic volume adjustment system, the Body# system (vibratory special effects), two sonic massage generators, Dolby Digital decoding and Dolby Virtual speaker encoding.

Amplifier inputs include optical, analog pair or inputs from BodySound’s BodyLink, a dedicated audio router that connects up to seven sources to the chair’s amp.

The BodySound software allows users to personalize their amplifier settings and save them as presets. The software runs on the company’s Control Link hardware and offered free of charge for running on a PC.
