Our Verdict
Samsung HW-T550
Samsung HW-A450
The Samsung HW-T550 and the Samsung HW-A450 are similarly performing soundbars but the HW-T550 has a slight edge. While both soundbars have a very neutral default sound profile and have very comparable overall performances, the HW-T550 is better built and has a virtual surround feature. It also has more inputs including a Full HDMI In port. However, the HW-A450 can get a bit louder.
