Review: Very Impressive Soundbar!! - This soundbar (Polk Signa Solo) is definitely a surprise to my expectations! I recently returned one from a different brand due to me being underwhelmed and defective so decided to go with this one. This one is perfect for a bedroom or small to medium living room. This is perfect for older TV units because this isn't equipped with a HDMI/ARC connection. It has an Optical and Line In for audio. The Bluetooth connects flawlessly! The only downside side is that the remote control is a cheap and flimsy design. Very small and could easily be misplaced. I think the remote under compliments the quality of the soundbar. Fortunately the learning code that Polk has will highly likely connect to any premium TV remote control that offers universal connection. You may only be able to control the volume and not the other functions, at least in my case. Overall it is definitely a good soundbar with a good sound!
Review: Sound is goood, limited interfacing with TV - I have all Polk speakers for my surround setup, and bookshelf speakers for the TV upstairs that sound great, so I wanted to stay with Polk Audio for my sound bar. I am connecting it to a 43" TCL 5 TV. The setup was pretty easy, just plugged in the included TOS cable and it worked. The cable is cheap, but it does work. The sound was very good for dialog, and even for music. It does not have the low bass punch that a sub could give, but it should be OK for most viewing. I tried it against a plaster wall, so the sound from the bass ports could bounce out from the rear facing openings. If that is all you need, then these are good for <$100 speakers. The issue I really have with this is controlling the audio. I tried programming it with a Roku remote, and it couldn't register the up and down volume. The Roku remotes all use the same signaling, and there are a ton of them out there, so I was surprised by this. Also, there is no mute function to program, since you can only select the buttons on the top of the bar. A mute function is critical to me to instantly mute if I have to talk on the phone, and I didn't want to have to use the separate Polk remote just for that. Also, as with all TOS connections (I think), you only get a line feed. You can't control the volume coming in. One thing it does do is turn on if it senses an input on the TOS link. That is good if that is what you want it to do, but not if you are trying to purposely keep it off. Also, it does not shut off when you shut off the TV, so it's just a sound sensor. I didn't even get to test the Bluetooth, since I've already determined that I need to move up to the Signa S2 with the HDMI ARC control. Also, the additional sub would be nice.

### ⭐⭐⭐⭐⭐ Very good sound and features
*by O***A on December 30, 2018*

This is a great performer for a very good price making it a great value. TV speakers on newer flat screens are typically tinny sounding and fail to deliver the type of sound the other wise excellent picture deserves. Enter the Polk Sound bar. It delivers decent base without booming, and great sound across the frequency spectrum. It also is Bluetooth capable and used frequently in our installation. I have been a Polk fan since they started making small bookshelf monitors in the 80's and still have two pair that sound as good today as they did when I bought them 30+years ago. Features I like include the auto-on and off when the TV is powered. The sound bar can be easily configured to respond to the TV/Sat receiver remote control reducing clutter. Skip the bulky 2.1 set-ups if you want simplicity, ease of use and useful features.
