The X Rocker Gaming Chair | XRockerGamingChairs.com xrockergamingchairs.com/the-x-rocker-gaming-chair CachedAudio TechnologiesVibrationConnectivity & Chair LinkingErgonomicsAssembly & MaintenanceStereo Speakers— The majority of the chairs include a pair of stereo speakers built into the headrest for optimal proximity to the user's ears. These speakers can be side-facing for more ambient sound, or forward facing to direct the sound toward the user. Subwoofer— A subwoofer built into the chair's back or seat provides a deep, resonant bass that can be felt. Enhanced bass tones are what fills a room or a theater, and provides a richer audio experience. AFM Technology— X Rocker claims to use an “exclusive AFM Technology.” AFM (Audio Frequency Modulation) is an audio reproduction method used in Hi-Fi stereo systems for more accurate synthesis of sound and improved audio quality. Surround Sound— Select models will include a total of 5 Speakers (two in the headrest, two in the seat, and a subwoofer) for 4.1 Surround Sound, providing for a completely immersive audio experience with compatible gaming consoles.
