With something rare and notable like that, condition is everything. Apparently, they have an amplifier and equalizer built in; do those work properly? Do you also have the boxes?

Bose 2201 system
In December 1, 1959, Amar G. Bose received a patent number 2,915,588 titled Pressure Wave Generation. This was described as a radiating surface of a sphere, 1/2 sphere, 1/4 sphere or 1/8 sphere. The radiating surface was to be composed of many small closely-spaced drivers in a sealed enclosure. It also describes a compensation network which boosts the high and low frequency ends of the spectrum to compensate for the fall off in response of the individual loudspeakers at these ends. Bose cited the Aceves patent mentioned above.
On June 12, 1962, Bose was awarded a second patent number 3,038,964 that further defines the spherical surface concept. The preferred placement is for one section in each corner of the room on the floor. The system was reviewed in High Fidelity magazine, January 1967. It shows an alternate placement, above, by putting the two eighth spheres together to form a quarter of a sphere and placed on the floor against the wall. Each section contains 22 five-inch drivers mounted in a triangular shaped convex baffle which is framed in walnut and faced with grille covering. The enclosure is completely sealed. Inside is a self-powered 50 watt solid-state basic amplifier that drives the speakers and which itself is fed from a spectral circuit known as a “spectral matching network” (in other words, an equalizer circuit, shown below). Of course, placing the system, or any other system, in the corner on the floor provides a higher bass output.
