You may want to contact Frankieve Audioworks directly. He had one in the store when I went to demo the Pa3x, I had no real interest in the bar, he played the Pa3x thru it, sounded decent but I really didn't listen carefully. If I'm not mistaken downside it only faces you the player not the audience.
Its not meant for playing at an audience, its meant for playing at home, or for using as a monitor.
