I think most of us here would love the Bose PAS.
As far as the speaker being behind the player, I just don't think it matters given the speed that sound waves travel through the air.
It's not so much a matter of where the speaker is but of how close it is to the player.
The preview does not come from the sound hitting the player first but rather from the player being able to hear the tiniest of notes played at the lowest possibole volume before the audience can hear them.
That could happen with the speaker placed anywhere so long as it is closer to the player than the audience.
If you ever see someone playing a fretless bass they will often do the exact same thing.
They start the note and adjust it before it is audbile to the audience.
It's a little easier with the bass since you can actually feel the onstrument in your hand but there is still some wiggle room regarding placement of the fingers and hand.
Other than that, it's just a matter of preference.
You should try ot play with a set-up that matches what you used to rehearse as closely as possible.
