From my experience with Klipsch powered desktops they went haywire after a few months use. The volume control was screwy. A friend who had the same set also had the same issue so I looked into it and apparently I wasn't the only one. Popular opinion says sometimes their electronics aren't all that great , even though the speakers themselves may be great. Unless they have used better quality components now to go along with the speakers. Maybe I got a set from a bad batch. There certainly were enough others online with the same issue.
That being said my brother went ahead and picked up the 2.1 setup ( wired ) and has had no issues, and they crank. Look deep into reviews on a particular model first( like I have to tell you that ). He's totally happy with his wired version of the 2.1.
I would recommend actually listening to stuff first-hand with decent quality files you like. Hopefully there's a store nearby that has them on display and powered up. That's what sold me on my Audioengine A2's, which for my place are too loud to play even at half. I walked home after listening to them,and then walked straight back to the store again and bought them. Incredible sound.
There's no artificial bass enhancement which I like, and the bass is there enough for me. I can feel the wind coming out of the port at the front with a bass heavy track.
The A5's have the port at the back I think. Good quality for sure. I'd buy them again in a heartbeat.
I would second the A5's, and would get those if I didn't already have these A2's.
Check em out in person if at all possible.
You're probably not going to need to bother with a sub on the A5's from what I understand. If you really feel the need to down the road Audioengine also has an optional sub to go with them, but I doubt you'd need it.
