I'm sure you can change the perception of sound stage depth etc by moving them about just like regular speakers. Thought if I had a pair they would be put precisely where Keith's got them as the main advantage in my room would be great bass even close to the wall. Like keith says they are 'designed ' with the extra reinforcement of the back wall in mind ( I think ) .Don't get my wrong, I not attacking the D&D or Kii's, I'm sure they are amazing sounding speakers with the flexibly to help them work well in difficult situations.
But no one speaker can be all things to all people.
They are simply two small monitors making the best possible use of todays technologies to provide the best possible results within their limitations.
May well end up with a pair, see how I get on with the JBL 705p first.
I'm thinking of unloading all my kit, making my lounge 'sane' again and just having a pair of actives and live like a normal person
