L1 x 2 (with a twist) + B2
At a funeral in a church the other day, I noticed that the sound was very clear, well dispersed and none of the folks at the mics had to raise their voices. I couldn't see speaker systems in the places you'd normally see them (suspended from side walls or ceiling).
Eventually I spotted the system ... two L1 towers and a B2. And they carried the sound perfectly (as I would expect them to!). The B2 was placed on the side of the raised 'stage' (for want of a better word) but the L1 towers were bolted to the walls. I could see a clamp holding the two arrays together and the wallmounts were most likely fitted into the channel behind the towers. The towers were mounted on wooden wall panels so they were really discreet - difficult to spot.
Since the towers were not placed in powerstands (they were raised off the floor - I'd say about 8" from the floor), I tried to figure out how they were connected. All I could see was some wires rising off the floor and attached to the bottom of the towers.
My guess is that they've got some sort of adapter to plug into the bottom of the L1 array towers and both power and signals flow through that adapter.
Very interesting setup. Elegant and understated. And the sound was excellent. Would have loved to get photos to show you what I mean, but it was not appropriate at the time.
