What are the best bookshelf speakers you have used?

I am looking for something with a maximum of 120 watts.

If you are on a budget, as evidenced by your last question, Infinity and JBL make great bookshelf speakers for under $200 a pair. Again, don't worry about watts - it's quality that counts.

If you double that money, you can get some used B&W speakers off eBay (some of the best made speakers money can buy).

I have yamaha, jbl, and other brands throughout my home. I use B&W in my home theater. I have been building stereo, whole house, home theater, and other similar systems for about 20 years, and I haven't come across any speaker better (although I have heard some that were as good). can and string I have a pair of Infinity Primus 160 speakers and I really like them. I measure them at H14.5" x W8.5" x D11"

My Altec Lansing speakers do sound a bit better but they're as big as a refrigerator. The Infinity speakers put out a really great sound and I got them for less than $200 for the pair. I am really happy with mine!!!! Are you on a budget or is it "anything goes?" If you're like most of us I would suggest looking at vintage speakers. You can get a set of Acoustic Research AR4s that rival the best of today's speakers with much higher construction quality for less than $100.
