User Manual Yamaha ATS-1080 Sound Bars

Yes it has really nice bass. It plays music well and is perfect for an apartment. We use it in our camper and it rocks the walls off with bass if we let it. It is great for movies too. It has a voice button that makes a huge difference for movies. You can hear what they are saying very clearly. This is just a really well made and engineered sound bar.

You need some sort of audio output on your TV - but the 3 primary methods are covered. This speaker has HDMI ARC (audio return channel), digital optical, and a 3.5mm stereo connector. If your TV has RCA outputs, you could get a cable that has a 3.5mm connector on one end and red + white RCA connections on the other end.

Yes. also, this unit has great sound. I was going to connect a subwoofer but the bass is very good without one.

There are no built in sub-woofers. There are woofers and there is an output jack to connect a sub-woofer to the sound bar

Yes, there is an adjustment for subwoofer volume on the remote control. The effect on sound quality is entirely up to the listener's preference.

Yes. It has Bluetooth capabilities. So a laptop with Bluetooth should connect just fine. Also there is an analogue input which could be accomplished through the audio out of a projector if the audio signal is sent to the projector via HDMI.
