I received a very damaged box containing the TCL Fire TV Edition Alto 8+ Soundbar that I purchased on sale during Black Friday. I was attracted to the price and the fact that it claims to contain a Fire TV 4K Stick. At the moment, I'm not so sure this is really the case as I have several 4K Sticks already installed and working with a Mouse Toggle program. For some reason, I can install and "Start" the application, but double clicking the play button quickly does not seem to enable the onscreen mouse cursor and pressing the 4 way ring and Select buttons don't seem to do anything that would lead me to believe the Mouse Toggle Program is working. For this reason, I'm beginning to doubt that there is really a full blown 4K stick inside this device.
On the other hand, the sound is just OK and the difference in actual sound output when selecting "News", "Music" or "Movie", then pressing the Select Key while playing Music, News or a Movie is virtually indistinguishable to the human ear. As with most soundbars I have tested, the Bass is poor at best and when playing spotify music, if you crank the volume up to 70 percent or so, some of the songs will cause the built in subwoofers or woofers to crackle during heavy bass notes. It claims to have a 30w Amp built in, but you have to divide that output across 6 speakers, so yeah, not very loud compared to a traditional home theater system. It is however a little better than the down facing speakers on the TV hanging on the wall. One concern is that 4 speakers, 2 SubWoofers and 2 mid range Woofer speakers send sound straight up and only 2 tiny tweeter speakers send sound out the front of the soundbar. Mounting the unit on the wall under the TV simply pushes all of the sound up under and behind the wall mounted TV so that was disappointing. I ended up placing the soundbar on top of the TV wedged at an angle between the wall and the top edge of the TV with the front speakers facing directly towards the viewing audience at about a 60-70 degree angle. This also causes the mid range woofer and subwoofer speakers to send sound up to the 8 foot tall ceiling where it bounces off and out towards the audience in front of the TV Screen. Fortunately, the sound bar is exactly the same width as the 42" TV under it, so it almost looks like it belongs there. It is about 1 foot below the ceiling.
I also use an Off Air ATSC Antenna which I bring in through a SiliconDust HDHomerun device, and in my area, 2 of the 4 major networks still push out an Interlaced 1080i signal. If you have tried to play this signal using the HDHomerun Application or through the Kodi MythTV Application (Which I use for my DVR) on earlier Fire TV Devices such as the Fire TV Box ver 1 and 2 or the Fire TV Stick, Version 2, you will quickly see that there is NO Deinterlacing done in hardware, and the result is a horrible grainy picture display. The Fire TV 3 Pendant, Fire TV 4K Stick, and it appears this TLC Alto 8+ Fire TV Soundbar DO in fact perform Hardware Deinterlacing right on the devices which outputs a nice clear HD picture as one would expect to see. Overall, the performance of the Fire TV part of the device appears to be similar to that of the normal Fire TV 4K Stick with the exception of the Mouse Toggle Program working for me. This device needs AC Power and does not use a wall wart. Also, there is no way I can see to use an OTG Cable to Expand the Memory of the internal Fire TV device, so that was a bit of a let down. So with all of that said, I guess the $75 that I paid for it on Black Friday was a fair price for what was delivered.
