Summary: If your looking for great sound that takes up little space, these speakers are the answer. Yes you will need a sub-woofer but you will be pleasantly surprised at the sound these small babies put out. A recommended buy.
Summary: I have not done any audio analyses on these speakers, but the sound is great. I had an old Cambridge Soundworks 2.1 system and one speaker blew. I bought a low-mid range system to replace the bad Cambridge Soundworks and was very disappointed, and quickly removed it from my setup.
Summary: Received them as a gift for Christmas 2012. Built very sturdy, and very sleek design. I knew when ordering, that these little guys didn't have much for low end, but if you're adding them to a system, they do extremely well amplifying the highs.
Summary: I needed a really small speaker and did not want one that sounded like a tin can or that hollow/boomy sound so many of the low end speakers have. The clarity of these is fantastic. As long as you don't expect really poweful bass I highly recommend these.
Summary: I like the size and sound of these speakers so far... I use them as rear surround in my home theater system. it's a lot smaller than my previous pair, and the sound is more pleasant also. It's a good buy for the price.
