Hey BBB, and Mike (and Eddie!) thanks for your kind words - much appreciated.
Yes we often put the Bose slightly in front of us, or to the side, or anywhere we like (within reason) when the stage cannot accommodate the "classic position" i.e. when the stage isn't deep enough to put the PA behind us - about 85% of the time.
It doesn't really matter where you put it we've found - as long as it's not very far away, and as long as there is some elevation (say 2-3 feet) because if the Dancefloor is packed, you will have trouble re the sound being absorbed by many bodies if it's not slightly above the crowd.
When you stand in front of the Bose, it's very very special (wrapped in the sound - hearing essentially what the audience hears), when you're behind, it's not as "heavenly", but you can still hear everything pretty clearly, especially vocals - more than any conventional PA we've ever used - no monitor required.
In other words, we're not afraid to place the Bose just about anywhere (within reason) at any gig, at any time.
