Another alternative could be MicroLab SOLO6C...thats them in the background of my Pic thingy, there actives so sorry if your after passives! I have mine on my desk close to me and they sound great!
Yeh you have never heard of microlab but more people should have... got these a few months back and I can whole heartedly reccomend them...they are crazy for the price of £70 over here in the UK, you can connect a 3.5mm or RCA aux in too, they have built in EQ and a remote...bloddy brilliant and solidly made too, with thick wooden panels, if Microlab had the mark up of more mainstream companies like M-Audio, or Swan etc they would quite literally be 2-3 times the price, and still then I would still be over the moon with the SQ for that price!
Soundstage is a little narrow but that is the only thing i can say are bad about these speakers! clarity, mids and highs are all very good...bass even shocked me quite a bit for such small speakers, (bigger than your average set of 2.0´s with their 6.5" woofers!) but I had already bought a used wharfedale SW150 10" subwoofer, and I have to admit this setup really has to be up there for one of the best bang for buck things i have ever gotten, compared with my parents B&W 684 floorstanders with an arcam solo neo, this 2.1 setup > Titanium HD really does compete well considering its a fraction of the price!
If your not a basshead then you will find the Microlab just fine with no sub...heck I sometimes dont even turn it on and dont feel I am missing anything, only thing is when you put on some dubstep or similar with bass that extends past 30Hz then that is where a sub does add more of a benefit as you can sense the Micrlobs start straining, but still put on a good show!
Also for the price I doubt you will find any active set that can go louder...when my parents go out and i have a few friends over they literally shake the house LO...as in i go downstairs and glasses are shaking, and this is WITHOUT the sub!
This review sums it up quite nicely...http://www.tweaktown.com/reviews/4112/microlab_solo6c_powered_stereo_speakers_review/index5.html
Sooooo glad i went for these over the swans as i really cant see the extra cash giving me a big bump in SQ...you would be better upgrading your soundcard!
Pics dont do the speakers justice, I love the retro look of em´ (wood panels look great!)
EDIT: I think i made these seem like a bass heavy set of speakers...and I would just like to clear this up, they are more on the bright side than dark tbh...but after a bump in the built in bass EQ and the treble EQ the balence is lovely, they are neutral with no EQ but i like it with an authoritive bass thump, and these are capable of producing that with the help of EQ, whilst retaining great levels of clarity and full mids with sparkly treble!
