I don't like to recommend brands of speakers for two reasons because speaker selection is very individual choice.
[*] I am in my 60's and during my life I played with fire crackers, served in Vietnam, rode motorcycles, and listened to loud music. I did just about everything a person can do to destroy ones natural hearing which resulted in me getting hearing aids this summer. What I found out is I have a rather significant hearing loss in the mid range frequencies (woman's voice) and pretty normal bass and treble hearing. Therefore, before I knew this I was naturally attracted to speakers that were either flat sounding or tended to be strong in the upper mid range. I didn't like systems with a strong or dominate bass or those with strong high range, for example those with horn tweeters, because when I played them loud enough to fill my mid range loss their strong bass and treble would annoy me. Given that we all have a different hearing profile what might sound good to me many not sound good to your ears. [*] Before I renovated my family room to my present 5.1 HT I had a combination of 1970's vintage equipment, six large speakers , two receivers, and lots of other audio equipment littering the room. My goal was to add a 52" LCD, a modern 7.1 receiver and a 5.1 speaker system, and change the whole furniture arrangement so that it would best fit the Dolby labs guidelines, and reduce clutter. To effectively do this I determined that a satellite type 5.1 system would best meet those goals. Therefore, I narrowed my search to those type of systems and didn't even look at large tower or large bookshelf systems. Given my hearing loss, goals and budget after much listening I purchased the B&W M-1 system, and after having it for two years I am very happy with it.
About the only speakers I would not recommend are any of the Bose Cube system and those that are sold out of white vans. Their are so many brands, styles, and price ranges within each brand its hard to make a specific recommendation. I tended to look at speakers who had good reviews and were made by the major players and could listen to at stores. In addition to the B&W's I also liked the Definitive Technology line, I also looked at Kilpsch, Energy, Polks, Marge, to name a few. I found the better listening rooms were found in the smaller Mom an Pop stores as opposed to the big chains like Best Buy. One thing I was not aware of at the time was the number of quality Internet direct sellers like SVS and Axiom who have pretty liberal return polices. SVS has $1,000 a system that would have worked for me and I would defiantly give them a look if I were in the market today.
My advise to you is design your room layout and then determine what kind and size of speakers will work best for you, If size does not matter then set your budget and start listening to as many brands as you can. You will also find almost as much difference in sound as you go up in price in a particular brand as you do in difference in brands. I started with a $600 speaker budget but had to double it to find something I was happy with.
