-- If your budget is really low, a pair of Altec-Lansing BXR1120 speakers are really good: http://www.alteclansing.com/bxr1120-...-speakers.html
. I bought a set (pair), for use with a PC, from my local office supply store. They sound surprisingly good, better than 2 small, low cost, speakers should.
The Logitech Z130 stereo speakers (http://www.logitech.com/en-us/speake...s/devices/6684
) are a little more expensive, but are good too. They should be available at your local computer store or Best Buy. They may not be quite as good as the cheaper BXR1120, IMHO.
The M-Audio AV40 speakers are a very good choice (I just looked them up). They make very good audio products. I did notice that you are looking at a much higher price than I thought (since you didn't say what your budget was). I, also, looked up the Audioengine 5 (A5), and those look very good too.
You should also look into the Klipsch ProMedia 2.1 system (less money than the M-Audio AV40s, at least the list price is). The ProMedia includes a subwoofer, which really makes a difference. I have the much older ProMedia 4.1, surround, system and it really rocks (it was rated as the best of all the PC speakers). At close range, it sounds as good as my main 5.1 channel surround sound system. The ProMedia speakers should be available from your local Best Buy, or you can buy it direct from Klipsch.
In terms of list price, the choices look like:
1) Klipsch ProMedia 2.1
2) M-Audio AV40
3) Audioengine 5 (A5)
All of those should do the job you require. The Audioengine looks like the best one (from a specification point of view). If you can, you need to listen to them, before you decide.
