I?ve got some experience with those speakers. In the late 70s I worked for an audio shop in Dubuque, IA called Great Sounds Audio. It?s still there. It?s in a small 2-story house. At that time, the store occupied half of the second floor (the other half was an apartment), my boss lived in half of the lower floor, and the other half was the office for the adjoining 6-room motel.
We carried EV home stereo speakers. If the dealer catalog, the biggest speaker was the EV 30 W. 30? across, the speaker cone is made of ?? thick Styrofoam. At the time, this was the most efficient speaker in the world in terms of converting electrical energy to acoustic energy. The cabinets for these things were the size of china hutches, about 10 feet tall. We actually sold 2 pairs of these behemoths.
As an aside, we did several installations of 20? and larger speakers into the walls of listening rooms. The adjoining room served as the enclosure. I don?t recall ever doing this with the EV 30s.
Anyway, EV didn?t sell a lot of these, and had to do something with them. So as a dealer incentive, they removed the magnets and the voice coils, attached a set of legs, a round Plexiglas top with the EV logo, and packaged it with 4 EV directors chairs. If you purchase $6,000 worth of product, you?d get a table and chair set.
My boss decided he needed 6 sets, so he orders many thousands of dollars worth of speakers. Probably more product than we had sold in the prior 18 months. He tells me nothing of this.
One afternoon the truck shows up with many many many speakers, which the driver kindly deposited at the back of the truck. I was working alone, and had to cart these boxes into the store, stacking them in the bosses living area. When the boss arrived, he decided to rent a storage space rather than sleep with the boxes, so I got to move them all twice in 1 day.
I visited the store last month; he still has one EV table set left at the store, and another at his house.
