The real surprise here is that you are pissed off. That was entirely predictable after you bought a miserable sound bar with mini speakers, and a puny useless sub. The problem is you lack common sense, which is actually rare, and not common.

[Packed into the Sony’s stylish case are two up-firing speakers, two beam tweeters and five front speakers. There’s also a built-in dual subwoofer for added bass.
