Electronics Expo via Amazon offers the Pioneer Dolby Atmos Add-On Speaker Pair, model no. SP-T22A-LR, for $99.99 with free shipping. That's $40 below our February mention and the lowest total price we could find by $99. Designed by Andrew Jones, these speakers work with Dolby Atmos-enabled systems to provide an extra layer of ceiling-reflected sound; each features a top-firing 4" concentric driver, 0.5" tweeter, and integrated grill.
