Thanks for all of your repies.
I am not a big fan of the 4000's put together under a screen, I always have a feeling of afterthought when I see this configeration.
I will have to go down to my dealer (what a bummer!) and audition the 3500's. I am still convinced that the design of the speaker, (very B&O, It's lifespan say's it all), fit's my application, the 3500's have got to sound better than pioneer, panny and the like tv speakers. I will update as and when.
I am quite suprised that B&O have not developed the 3500's, they would look great as an outdoor speaker, in the middle of 2 patio heaters (I'm from England)
