Yesterday, the Samsung HW-F 450 returned to Amazon because it was not yet, unfortunately, in the treble range as expected. Review can be read in the article description of the HW-F 450. So yesterday the Samsung HW-F551 in silver bestellt.Dank Amazon Turbo delivery as always, the Postman today morning rang for the third time with a sound bar on the door. Package fix opened and immediately impressed by the sleek looks and the quality of materials (metal grill on three sides plus processed top .Subwoofer round edges, provides much higher quality than it show the photos on the net. So from the appearance I have been very satisfied. So now came the 4 th Soundbar in 6 months for use by LG NB2520A, Yamaha Yas 101, LG NB3730A, Samsung HW-F450 !! Connected via ARC .The HW F 551 is already louder from the basic volume and a lot clearer in sound than any other Sounbars I've tested. In the treble, it is worlds better, such as the Samsung HW-F450 because you realize the additional cost Samsung F551 HW .Klare voices, very clean sound, just great sound .Then the Blueray Casino Royal started, and after 5 minutes I knew this would be my Soundbar which was partially .Very high quality workmanship, looks classy in silver .Klang my feeling very balanced treble, middle and bass range .These Soundbar is worth the money !!
