These speakers have so much depth in the sound stage. Vocals come through clean and very highly believable without distortion on most of my CD collection and even poorly recorded CDs sound better with these speakers. The midrange is measured very well and the bass is tight and you can feel it when they are cranked up. I can listen to the F20s all day and not notice any ear fatigue. As far as looks, the piano black is a beautiful mirror finish and the black stainless outriggers not only look cool but are so easy to adjust with a twist if the hand...no tools required. Also, they are bottom ported so if you are limited on space these can be placed closer to the wall than most other tower speakers (i keep mine about 16" from the wall) I do highly recommend these and i think they are worth every penny. I cannot think of anything I dislike so all i can say is go for it if your considering these tower speakers

These speakers are great as standalone speakers. Their bass digs decently deep with great resolve on the tweeter. The soundstage is good with very good separation of instruments and vocals. Present a great a center image. I will say if you have good subs already at your disposal, opt for the XT B100 bookshelves from Martin Logan’s. Doing a direct AB between these two, it was very apparent how the motion XT tweeter shines over the motion tweeter in these. The B100s have a very transparent sound, much better depth and a greater sense of scale surprisingly. They completely disappear and the sounds seems like it’s coming from a large canvas. A true marvel at their price. Just remember, they do not have solid bass and should be used with a sub, preferably crossing over at 80-100hz depending on your room and subs. Used a denon x4800h bi-amped for both speakers. If you have the space, B100 with good subs 100%!
