For around $100 or so, I bought an Altec Lansing 2.1 setup a few years ago for one of my PCs. I'd venture the current line up is better perhaps, but I'm more than happy with it. Given the pc's controls, it's own bass and treble and vol knobs being right up front, and with a mini headphone jack, they fit the bill indeed.
Klipsch too was a consideration.
All the threads I've read here and elsewhere on active speakers, especially for use with pc based (office, bedroom) systems have indicated to me a fairly substatial investment is required to out run these desktop systems.
I've thought about it/them though... but figured to put my $$$ to better use elsewhere. Good active speakers for $200 it seems is asking a bit much.
I now recall a DAC oriented set of speakers that went off for $250 which were getting a lot of press not long ago... sorry, but I don't recall the maker, but it's resonably prominent. I think they went up to $299 after the introdution period.
