When I first was setting this up I wasn't expecting to be so surprised to the quality of sound this has. I began setting up the rear speakers & subwoofer first. Then set up the soundbar. I turned on the subwoofer first as it needs to be seen by the soundbar to connect. The light around power button was flashing, Then turning on soundbar it instantly auto connected & went solid. Rear speakers are powered by the subwoofer & comes with very nice long RCA cables to connect them, so one can have wide rear placement or rear speakers if desired. Why are the cables always black in color? We don't paint our walls black so the cable sticks out badly on any light color wall. Why can't they be white or almond color? As always the brackets for the rear speakers are non adjustable, another issue I wish all companies would fix, providing adjustable brackets. The subwoofer is bottom firing, but speaker is totally exposed. I wish it had a metalic grill over it to protect it like the soundbar front & the rear speakers are made. No worry about damage to any of those. I do get it that the subwoofer is smaller than we all would like, but with the amplifier/Bluetooth connectivity it has, a larger one would put this system much higher in cost. The app is excellent and provides firmware updating using the app. I do wish it had more controls in it, such as surround level, bass/mid/treble that is only available by using remote. Remote is well designed with great functionality, but sadly it's not Bluetooth, just infrared. It has excellent surround sound level with it set at max+6 setting. Still sub has very decent bass with bass set at +6 & using movie setting on EQ in app I found it to be very good for it's size. Overall vocals/surround sound is amazing! I cannot believe this system produces this much big sound from such a small package! Vocal & night EQ settings are great for quieter listening when someone else in the home is sleeping. Switching to Bluetooth I listened to some tunes with my phone which is also excellent. I love the front display. Volume number shows up on display matching my tv, shows what connection input being used, & has brightness level adjustments, sound prompt volume adjustment for on/off prompt, & can be shut off if desired. Very nice features for a low price unit also. I highly recommend this system to anybody out there, especially if you are on a poor boy budget. You definitely get maximum bang for your buck for this!
