These are my "surround" speakers for my living room stereo:

They were built by my wife's best friend's stepfather, who was this amazing tinkerer, builder, inventor. In the '60's, he wired his entire house as a multi-zone audio system, with a switch-bay that turned speakers on and off through out the house. He also built most of the amps that powered the whole system, I think they were Heathkits. There were wall-mounted speakers in these exquisite little boxes in every room. These were his main stereo pair.
The larger one is about 18" in diameter and has 15 drivers, and the smaller is 13" with 11 drivers. There are 3 different types of drivers in the system, but there doesn't seem to be any system as to how the drivers are laid out. They do sound really good, they lack extreme lows and highs, but project the mids beautifully into the room. I have a pair of Infinity's that take care of the lows and highs.
I got the speakers after our friend's stepfather passed away, no-one could figure out how to get sound out of the system, and they bought modern equipment to replace his stuff. As it turned out, the only reason they couldn't get sound out of the whole system was because they had the tape-monitor engaged on the main receiver! They gave me these in exchange for setting up their new system, but as far as I knew, everything in his old system worked.
We used them for the cover of the Xenat-Ra LP:
