Sony HT-A9 Wireless Pro Home Theater System

Whether you're addicted to action films or fall in love with rom-coms and dramas constantly, there's more to cinema than just the screen. That's why the proper sonic engineers crafted the Sony HT-A9, a surround-sound home theater system made for wireless performance. This high-powered, low-maintenance collection of speakers by Sony is made to drive up the performance of every sonic aspect you hear. It's all crafted for the modern user who expects more: there's no need to fiddle and fuss, or move components from one side of the room to the other. Instead, these speakers make their own audio adjustments. Simply use the brand's Sound Field Optimization feature to create the optimal setup. The Sony HT-A9 will map out the room for you. This Sony home theater system measures the distance between the included speakers and your ceiling for a completely optimized sonic experience.

The Sony HT-A9 is truly a premium product packed with more features audiophiles want, demand and love. Technology-wise, its 360 Spatial Sound sets this system apart from the pack. With this technology, users are engulfed by 12 "phantom speakers". It's not all about invisible sound, though. This home speaker system is made for modern life. Connect to your smartphone via Bluetooth and hear music in a completely new way, or use voice commands via Amazon Alexa or Google Assistant. For true compatibility, pair these speakers with a Bravia Sony TV. That way, the TV itself functions as the center-channel speaker. That's true entertainment that coexists in harmony.
