I have an old Boston Acoustics CR400 powered subwoofer, and a pair of their Micro 80x wired passive bookshelf speakers. The specs for each are below. I want to set them up so I can use them with my Samsung LN46B550 TV (regular TV, not smart; has Roku) and to play music from my (Windows) laptop. The TV connection would be wired, and the PC connection would be Bluetooth (or it could be Wifi if that would be better). \n\nThe available inputs on the subwoofer are RCA connections for line-level in, and the speaker-level inputs (and outputs) are screw-on posts that take wires or banana plugs. There are no optical or HDMI connections. Diagram of the connections is below.\n\nI tried connecting the speakers to the subwoofer and then connecting the TV audio out to the subwoofer but while the subwoofer seemed to work fine, I got almost imperceptible sound from the speakers when I connected the TV to the speaker-level input, and no sound at all when I connected it to line-level input.\n\nI'm setting all of this up in a fairly small room (17' x 11'). I want to keep my costs extremely low, but still have decent sound quality. Unless there's a better way to go, I'm thinking I could get a soundbar and use that to connect everything. There are a lot for under $100 on Amazon that have gotten decent reviews from Audio magazines. \n\nI need some advice on what to buy and how to connect everything. If a soundbar will work, what does it need to have? Since I have a separate subwoofer, would I want 2.0, 2.1, or something else? I saw an article that said 50w per channel would be good for a small room. Does that sound right? Do I need a receiver? What's the best way to connect everything? \n\nThanks in advance!
