Summary: I feel compelled to answer one of my own burning questions from when I bought these speakers: yes, a subwoofer does indeed improve the sound! I use the 8" sub from the same B&W series to get that extra punch (I think of it as "wetness") in pop-ish stuff and some modern big-band jazz. It really lifts the experience to nirvana! That said: excellent speakers with a wonderful deep bass, yet on the lean side.
Summary: For a long time I had owned Linn Keilidh floorstanders which in a few words I would describe as sophisticated, laid back floorstanders with a wide, impressive sound stage, very smooth and easy to listen for long hours. However, they were missing some enthusiasm, had rather weak mid range, and overall were not too much evolving.
Summary: These speakers are pretty good. Let me first explain my situation. I have a small 12'x18' room with hardwood floors and 9' ceilings. I wanted a good pair of bookshelves with a sub port to create a simple audio package. I'm using only these, and no sub. The speakers are easy to use, and directly out of the box have a great, solid, smooth, and clear sound.
Summary: I am a drummer and have been listening to many various types of music including classical, over the past 45 years. Having previously also owned the B&W 602s3 speakers, all I can say is that these speakers are mightily impressive. I bought the speakers and a Nad C355BEE amp a couple of months ago and have only felt that the speakers are now on their way to being fully run-in. From week to week, they really do sound better and better.
Summary: Je ne peux me faire une idée précise de la qualité des enceintes pour cause de voisinage. L'écoute d'enceintes en niveau 'ambiance' n'est pas idéale pour les apprécier pleinement, surtout si je les confronte à des casques haut de gamme tels que AKG K1000 ou K701, qui mettent l'auditeur sur les genoux des musiciens de l'orchestre !
Summary: très bonnes enceintes bibliothèque qui ravira les oreilles de mélomanes pour un budget et encombrement mesuré. Je ne regrette en aucun cas cet achat . Ne convient pas avec un ampli à tube ... je l'ai couplé avec un ampli cambridge : magnifique !
