The Model II system also features Articulated Array speaker technology for better tonal balance. The loudspeaker's 24 vertically mounted drivers are precisely angled to create clearer highs and more consistent tone in the room. Even people off to the sides of these stage speakers enjoy well-balanced, detailed sound. My Bose L1 Model II systems come with two or Four Bass Subs for that deep sound depending on the size of the room. When it's time for Speeches you want the people at the back of the room to hear you, and my Bose speaker system will deliver that. I use a Separate Bose System for your Ceremony so you will get that crystal clear sound, and when you go to do your vows your guest will hear every word you say.
