Pioneer SP-BS22A-LR 4" Andrew Jones 2-Way Bookshelf Speaker Pair for Dolby Atmos
Based on the industry favorite SP-BS22-LR, these Dolby Atmos ready compact speakers deliver a huge surround sound. Using the technology in the Elite Home Theater System, designer Andrew Jones implemented the CST technology to power these speakers with a concentric designed driver. With the tweeter inside of the woofer in a concentric array, these speakers are able to deliver more detail than other Dolby Atmos-compatible speakers that use a single driver.
The SP-BS22A utilizes a multi-element crossover to ensure that the high frequencies are routed to the tweeter, while the lows power the woofer. This allows for the speakers to sound as good in 5.1 surround sound as in Dolby Atmos. The curved design of the speaker helps eliminate standing waves that can occur in the speaker’s cabinet. This design also helps eliminate noise due to speaker vibration.
The top-firing concentric speaker which is composed of a 1/2" soft-dome tweeter inside of a 4" woofer, reflects audio off the ceiling to give a sense of height to the overall surround sound. The two-way driver design produces a much cleaner output than speakers that only use one full range driver.
