portable ipod speakers?

I agree with the Audioengine suggestion. You could even get creative and put them in a carrying of some kind.

Interesting thread as my college age daughter wanted these (claims she blew up her last rig) and the only simple smallish ones with a sub I found are the Klipsch. I ended up giving her an old set of Altec powered sub/sat speakers I had previously hooked up to an office computer. It drove me insane trying to find anything that might have any cojones for her "dubstep" addiction.

Don't know how "portable" you're looking for, but I have this setup and it sounds really nice.

Interesting stuff from Cambridge. By portable I mean having an active monitor w/ mini-jack or an all-in-one cradle/speaker box(i.e...simple connection). I have 2.1 M-Audio LX4 setup for my keyboards. Has to be best $200 setup ever. Shame they don't make them anymore. But this can't have a sub....too much stuff to drag around. She wants to take it to and from work. I might be able to talk her into 2 small monitors but that would take two wall plugs and I'm not sure how that mini-jack would get to a l/r unless they make a cable that breaks out that way. I should probably stick with something like this

I just looked at the the Audioengine and I like the minijack input with rca jumper. You could just keep the the two speakers connected and plug the ipod up as needed. Any other suggestions? Been helpful so far.

One of the Cambridge Soundworks Desktop Radios should work. Small with good sound and includes a built in iPod dock. The price is definitely right especially for the lower end models.
