Best speakers for small listening room

Paulwp . . . thanks for the input. I do like to B&W's and don't have any experience with other speakers in my small area to compare. I'd just like the bass to be "tighter". I've played with the setup and have the back of the speaker about 18" away from the back wall. Since it is an office, I don't have much flexibility. I don't really understand the "standing wave" thing. Joel

Im not sure I know what a standing wave is either but I know one when I hear one. It's sort of like turning on a light in a room full of mirrors. I can get my little mini-monitors, supposedly down 6db at 60hz, to put out a 10db peak at 60 hz if I put them in the wrong position in a perfectly symmetrical room.

What you want in your room with your electronics, I think, and some might disagree, is a small but warmish speaker. I've never heard of the Dynaudio speaker you mention, but the Contour 1.3 is small and very good. Not really warm though, might be a little bright with the Plinius in your room, unless Ive heard wrong. I would suggest little Spendors, but I dont think they're known for having "tight" bass.

For my home office, I chose to go with very inexpensive speakers, Acoustic Energy Aegis Ones, ample bass but not "tight," nice detail, but a little soft on top. I listen off axis closer to one speaker than the other and found that my cleaner, more revealing, more detailed little mini-monitors were too bright in that situation. Small rooms are tough, especially if you cant listen in the sweet spot.

Ok, I was curious so I did some research. I hadnt heard of the Dynaudio's you mentioned because I dont shop in that price range (on principal, sort of, but I guess if I were filthy rich I might). Properly sited they would probably be fine and a better match for your room than the B&W's.

Joel, having lived in confined space, the advice above is sound (no pun). Recommended for easy set-up: JM labs with careful positioning, strongly recommended -- BBC LS3/5A (used; don't think U get them new nowadays), Audio Physic Step. Not easy to balance the sound from yr B&Ws: IMO U need an unnecessarily big amp.
