I BOUGHT THIS PRODUCT A FEW DAYS AGO TOGETHER WITH THE SONY HT-A7000 SOUNDBAR AND THE SONY SA REARSPEAKERS 3S. INSTALLATION IS SIMPLE AND QUICK AND EACH SPEAKER SEEMLESSLY CONNECTS WIRELESSLY WITH THE MAIN SOUNDBAR, (YOU JUST HAVE TO FIND AN APPROPRIATE AREA IN YOUR ROOM CLOSE TO AN ELECTRICAL SOCKET FOR EACH SPEAKER). THE 7.1.2 SOUND SET UP, IS TRULY SPECTACULAR ENVELOPPING AND IMMERSING THE LISTENER WITH HIGH QUALITY AUDIO OR DOLBY ATMOS/DTS SOUND FROM BLU RAY, AUDIO CD AUDIO AND 4K UHD DISCS. THE SUBWOOFER PROVIDES SUBSTANTIAL SOLID AND POWERFUL BASE SOUND THAT COMPLIMENTS MY NEW SOUNDSYSTEM PERFECTLY. I'M IN SONIC HEAVEN EVERY TIME I USE MY NEW SOUNDBAR/SUBWOOFER SYSTEM!
