Summary: These are great little speakers. They have a small footprint and have a great balanced sound. They work great as stand alone speakers. I'm not sure I would pick them for a surround sound environment, but if you need stand-alone speakers with a small footprint, these are great.
Summary: I'm using these as the surround speakers (with larger Sony speakers in the front) and couldn't be more pleased. Sound is crisp and clean, and bass response is surprisingly good. My only quibble: no provisions for mounting (mine are on the wall, and I had to drill and pray). I have a pair of slightly larger Polk bookshelf speakers in my office, and these Sonys are almost as good for half the price.
Summary: I bought these to attach to my laptop and sit on my desktop, small size was important. The fractional watt headphone amplifier in the laptop is enough to push these to reasonable volume. A visit to radio shack and some quick soldering produced a cable. Not exactly hi-fi, but better than the 1 1/2 inch speakers in the laptop. The real use is listening to radio web streams while I work, and playback of my ripped CD collection.
Summary: These little speakers are quite amazing. I'm powering them with a 10 watt per channel integrated vacuum tube amp. Obviously, due to their size, they should be used along with a subwoofer. They weren't designed to blow out windows..... I have the Sony SA-WX700 dual 10 inch sub that they match up well with. The midrange clarity is outstanding for such a small speaker. The highs, unlike what others have stated, are very smooth and revealing, not harsh and grainy.
Summary: These speakers sound very good for the price. I have heard lots of $200 speakers that don't sound much better. The only difference in the speakers is the bass response. The sony speakers have almost no low response. You hardly get any bass. But for me that is not a problume for me though. I have two velodyne subs which pick up the low end frequences very well. One is a cht-10 and one is a spl-1000 which together have 1875 watts of total power.
Summary: These are great soundings little speakers for the price. The frequency range sounds fairly flat through it's advertised range 80MHZ-50KHZ. The highs don't roll off at 20KHZ like some cheaper speakers due to the extended range tweeter. This is important if you listen to any piano or electronic type music that produce frequencies in that range. The bass frequency response is good for it's size, but you will want to add a subwoofer if these are your main speakers.
