Hi. I'm using a pair of XL7F in a bright, but extremely large room. Driven by a Denon AVR, they sound really good. Room reflections are large in magnitude, but roughly equal in orientation. (Tile Floors, a mostly Glass wall matching an "art gallery with glass-framed large artworks, vaulted ceiling in an "A" shape.) I don't have carpet anywhere. My other room has a pair of Sierra-1 bookshelves. My "critical listening" consists of classical music, and I want speakers to reproduce genuine acoustical instruments. After considerable testing, I set the Fluance pair about one meter from the wall behind.
The Sierras have a bit more "precision, accuracy" in relatively soft music without excessive percussion. Flutes Clarinets, Oboes, and French horns have a good approximation for the timbre of the genuine instruments. Violins sound like they're made of wood (that's correct). I've been accused of having "Golden Ears", and would never confuse these speakers with real instruments. But they're reasonably close.
The Fluance set is not quite as accurate, "genuine" for these midrange instruments. But they sound better in momentary situautions when the music contains lots of percussion, or too much content in deep base frequencies. Also, In terms of a "stage", the XL7F pair does not have a lot of vertical presence. The horizontal dispersion is excellent, but the sound seems to come from only a narrow band of height- as short as the speakers themselves.
I'm extremely pleased with the quality of sound from the XL7F pair at this price point.
