After several searches on the Internet to procure a sound bar, my choice fell on the Yamaha YSP 2500 (I already have a sound bar of the same brand in my living room, the YAS 101).
After unpacking and installation in good and due form, I tested the sound bar before calibration with the film Prometheus Bluray (VO DTS-HD) and frankly I was a little disappointed: the sound parraissait fairly narrow, without really sitting in low and little or no surround effects ... Then I switched to the calibration with the supplied microphone, letting the system do its job for 3 minutes (pink noise) leaving the room.
On my return, and after backup in the internal memory of the bar (there are 3), I gave the same passage of the film ... and there miracle! A simply breathtaking and its crystalline, low very present but never invasive, well drawn surround effects ... in short, a pure delight! It's simple, my only piece of 12m2 seems much larger, the walls are pushed, I almost believe myself at the cinema. It's clean, bright, powerful ... even at half volume.
It's just incredible that such a sound could get out of a pregnant so fine!
I am fully satisfied after only 1 test day, I could not yet tested the Bluetooth music but for me the priority is to bluray movies (I have a Samsung OLED TV UE48H6400 and a bluray player Sony BDP S4200). I still have to dig through menus and make other tests.
I highly recommend!
