Imagine you get to design a brand new community hall or church building. I'm thinking of gear in the future not yet built.

What if (theoretically) you had similar L1 tower assembly and B1s/B2s, modifed to be fixed into the back wall of the stage, and there were five of them spaced 3m apart across the stage. Five T1 local stations could handle all the on stage musicians.

Would most of our sound problems be solved? Wouldn't need a mixer desk at the back, and the in ear monitors and the FOH etc. Anybody could use it without, needing the expert sound technician.

Is Bose heading in that direction?

Hi Valvenerd,

The Pro Bose folks will design a system to fit about any needs. The MA12 speakers that are very similar to the L1 series are available for built in installations and I am sure that a competent architect could work with Bose to provide a "hidden" space if it were desired.

I'm not sure that a church or community center could get away with not having a sound engineer on hand. Even with competent performers, to make meetings and entertainment festivities go smoothly you still might need someone to turn things on and off or up and down depending on the action on stage.

I got a chance to sit in while a local Bose installer gave a demo at our church. It was very enlightening. They brought a test rig that allowed them to place two columns (one on top of the other) in various locations. They then ran various test material into the system while we walked around the church and listened.

The resulting clarity was astounding compared to our present sound system. This church is very acoustically problematic and the line array systems are the obvious solution. The key is that they keep the sound from going into the upper portions of the facility, which add a lot of unwanted reflected sound. That 2-column tall test rig was an immediate improvement over our present system.

They did explain that, for a room the size of our church, they would go with 3 columns stacked on each side. The key factor here is how far you want to project the sound. The more drivers you stack vertically, the better the sound carries to the back.

While a number of L1s mounted on a back wall might work in smaller rooms, bigger rooms need more penetration and, therefor, taller line arrays.

The downside to the professional installation is simple: cost. This would have been a very expensive installation and our church hasn't been able to justify the expense with the present faltering economy. I really wish they could find the funds, though, because the Bose install would be such a massive upgrade over what we have now.
