We have been approached to quote a very large PA system for a government building. Although it sounds a bit excessive, they have indicated that we'll need to furnish 150 speakers on each of six floors (900 total). We'll propose a 70 volt system with a separate amplifier (or more) per floor. A single zone controller will allow access.

For simplicity in troubleshooting, we'll propose putting no more than ten speakers on each cable run.

The problem is that they want us to reuse the existing speaker enclosures and just replace the speakers/transformers themselves. The existing wall mount enclosures are fairly well made of steel, so I can see why they want to keep them. The problem is, I was hoping to find a source for 8" speakers with transformers without any kind of grille or enclosure. I'm not having much luck. I'd hate to buy ones with grilles just to take them apart. Any ideas?
