I am looking for the best speakers for listening to music, podcasts, videos and some light video and audio editing. I don't have a particular price in mind.
So which speakers are the best?
The following advice comes from Ars Technica and echoes what the posters what posters above have said but check it out nonetheless:

Logitech Z-5500 5.1 speakers
For computer speakers in a surround setup, the Logitech Z-5500s are among the better ones available. Serious audio aficionados will probably prefer actual home theater components...
If you can skip surround sound speaker setups, higher-quality stereo or 2.1 setups include the Swan M200MkIII, M-Audio BX8a, Behringer MS40, and Axiom Audiobyte v3. All tend to sound far better than even the best "multimedia" speakers generally found at your local computer retailer, but they aren't cheap, and they don't get ear-bleeding-loud or provide as much thump.
Another consideration is headphones or headsets, particularly for multiplayer gaming, or as another approach to hearing positional audio. The Sennheiser MM 450 headset or HD 595 headphones are a good start, along with the Etymotic ER-4p in-ear monitor (IEM), and honestly, the range of choices is huge. Browsing the Audio/Visual forum right here on Ars might be a good start if your audio needs go beyond the typical multimedia setup.
The Logitech Z-5500 5.1 setup packs 505W RMS total power, with 62W RMS to four channels and 69W RMS to the center, plus 188W RMS to the subwoofer. The 33Hz-20kHz frequency response and 93.5dB signal-to-noise ratio isn't too bad for computer speakers, although we advise that you focus more on the sound than the raw specs.
