It's amazing what your generation does with your audio equipment. When I was an undergrad, we shook the living crap out of most dorm floors ;).
That said, and understanding your budget and focus on digital music from the PC/iTunes/streaming/etc, you might consider not going with cheap PC speakers (the T40 is nothing spectacular, just cheap). Visit a used audio shop instead, or look online @ amazon or ecost.com to find a basic receiver with digital inputs. Brand is not much of an issue at your price point/budget. Used audio shops/craigslist/etc. will also be able to hook up up with budget speakers too to match this receiver that would be able to accommodate your digital sources *and* shake the walls. If you can spend $200 that would give you more wiggle room. Why bother with subpar computer speakers when the real deal is right there for the taking(!)
Hey there, just signed up to ask this question. I am looking for a good, affordable, set of speakers for use in my dorm room at school. Right now the set that I am considering are the creative gigaworks t40 (http://us.store.creative.com/Creative-GigaWorks-T40-Series-II-2.0/M/B001S14DYO.htm). They are around the price I am looking to spend (~$150) and seem to have great reviews concerning sound quality.
Anyone else have any suggestions? The GigaWorks were released in 2009, so I hope that somewhere out there someone has released a better set for around this price point.
Thanks! Let me know.
