I have looked at sound bars for years, and just felt like…nah…I don’t really need it, the TV sounds good enough. I have a TCL TV and a couple Insignia TVs – and the sound is good…but there is no going back after the Alto Sound Bar. The difference is incredible. The sound bar arrived in a couple days from Amazon, was incredibly simple to set up, and looks great. I was able to tuck the sound bar behind the TV, and you can’t even tell it’s there. The subwoofer, I was surprised how great it sounds for being wireless…as good as a wired subwoofer I have in another room. The ability to use my phone, and play music is an added bonus. I put a TCL TV in a sunroom addition, it was not wired for cable, so the TCL Roku TV has been in there for a couple years. But to play music…I had to turn the TV on, and use an app (or bring a small portable speaker)….now I just use the Alto Sound Bar – and it sounds great. The subwoofer… with music…you forget how great some bass sounds. I didn’t listen to an Alto w/o a subwoofer (saw it first at Best Buy, but was on a motorcycle and could buy it)– but if you are torn between the 2 versions…I strongly recommend the subwoofer. It is small, tucks in next to the couch, no wire (just power cord) and makes a huge difference. I haven’t tried it with a non-TCL TV, but the sound bar came with multiple ways to connect to TVs and should have no problem. The bonus w/a TCL TV is you use the one TV remote and it controls the volume/power for both. The Alto sound bar remote is small and simple. Nice job TCL.
