Home theater enthusiasts are excited about Dolby Atmos’ elevated sound technology, which creates a Height channel sound experience. The SP-T22A-LR add-on speakers were designed to add to your current compact speaker or floorstanding front speakers. Upgrading your AVR and adding on the Pioneer Add-on speakers allows for Dolby Atmos content to come alive. The SP-T22A-LR uses an upward-firing concentric driver array to reflect sound off the ceiling to produce a truly heightened sound experience while integrating with your already established home theater system. The SP-T22A-LR was designed for use with the Pioneer SP-BS22-LR compact speaker or SP-FS52 floorstanding speakers, but are also compatible with most speakers that have a flat top big enough to fit the SP-T22A-LR. Add two SP-T22A-LRs and a Dolby Atmos-enabled receiver, to upgrade your existing surround sound to Dolby Atmos.
