I have 4 of these connected to a Beovision 9 (the Lounge). They sound great but...I have a 'movie room' with 2 Beolab 9's (as fronts) and 2 Beolab 3 as rears, and a sub...The sound from the Lounge doesn't compare to the Movie room (obviously I guess)...Which is fine as I use the setup in the Lounge for general viewing, and use the movie room for, well, movies...
What I'm getting at is I can compare the two, and my advice to you is if you're thinking of these speakers to watch movies on, they need the sub. If you can get these and the sub, I would. They sound nice, but with the sub they are sweet...I had the sub in the lounge for a bit, and when I took it out it made a hell of a difference. I was actually suprised at how much they do get used as rears as well, I personally think they are worth having there.
Hope that helps.
