Sorry for any duplication, but I've got a question for any owners of the 830W. For the rear speakers, can you detach them from the stand and have them just stand-alone, sitting on a surface? I've not got room for the wide base on the floor, so may need to have them 'as is'. Are they able to sit flat or does have to be on a stand or wall mounted? Without nipping to Comet to check (I'd really want to order them this afternoon to pick up on the way home tonight! ) can anyone enlighten me? Cheers!
