<font color='#000000'>I recently bought a pair of Cerwin-Vega V-5m for my computer, and they seem to be quality units so far. The cabinets are almost solid when rapping my knuckles on them.
These particular ones have a 5.25" woofer and a poly tweeter. Power handling is very good. The frequency response has some midrange peaks (found this out through equalizing it out since it was making my head hurt), but for a $50 set of speakers I was expecting a bit worse, especially considering I am using them for near-field listening.
Cerwin-Vega since they first started making speakers has had a reputation for power handling and volume. From my experience with their car audio and now their home audio I like their smaller speakers (for car their separates) for their good price to performance ratio, but I have yet to like any of their subwoofers.
Just give those V10f speakers a listen, then go look at a similar product. Just make sure you give at least 4 or 5 speaker sets a good listening to so you have more to compare against.
**EDIT**
I now have had them for almost a month now, and I've since adedd a Yamaha YST-SW215 subwoofer to it. The reciever is a Yamaha RX-V430. I'm still tuning the sub to my tastes, which is hard when you have no SPL meter or any RTA setup of any kind. The end result is still downright awesome for anyone looking for some nice PC sound system.</font>
