Along with that limitation, both budget and space constraints seem to be problematic in your case. I was going to suggest a very simple refurb HTIB. Airplay speakers are also on the expensive side, and generally aren't anything impressive/can't be separated physically (like a sound bar is fixed per se). Hmmmm.
OTOH, how about the audioengine A2?
Not certain though if input 'B' on the A2 would permit you to connect via 3.5mm output from your other devices.
I wonder if the D1 would be an additional solution, or something similar-
Will have to graph this out and think about it in a little more detail. Is there *any* way you can fit in a very compact HTIB rig(?) Would make things much easier, especially feature wise.
I currently have a TV (digital and analog audio output), Fios cable box, and a 3rd gen Apple TV. They used to be connected to an old Sony DAV-X1 (HTIB), which did a fairly good job, but which I can no longer use. Given that the TV speakers are awful, I am trying to find a good speaker alternative. I'm on a very tight budget (under $250) and have limited physical space (so probably no AV receiver), but would like as good quality sound as possible because I listen to a lot of music from the ATV. I also need some way to control the volume by remote, because I don't want to have to get up each time I have to change the volume and the only way I can use external speakers with this TV is by turning the TV's volume all the way down. Lastly, a soundbar is not ideal because of limited space and sound quality for music generally isn't great.
Any suggestions for a reasonably-priced 2.1 (or even 2.0) solution would be greatly appreciated. Thanks!
