Conclusion: The Samsung HW-E550 is a flexible home theater sound system, with plenty of included hardware for various mounting options, but it suffers from mediocre audio quality and a slightly too-high price.
Pros: Supports Bluetooth wireless streaming. Multiple speaker configurations add placement flexibility. Includes HDMI, coaxial, and analog connectivity, plus wall-mounting hardware and speaker stands. Useful remote.
Cons: Input ports are located on the subwoofer's back panel, which is tough to reach. Can sound a little thin and bright with music. Confusing manual.
