If you're meaning computer speakers, I would be looking more towards what is most common rather than most accurate. You already got plenty of accuracy. Commonness might give a better idea of what most people are listening to. I use some really cheap noname ones that came with an Emachine computer I had. Really helps when I am making things meant to be heard on web sites. The most common are probably the Creative (Cambridge? whatever, the SoundBlaster guys), like these perhaps?:

or maybe whichever are the stock Dell ones, lol.
