That picture is 23 years old. Those were my pride and joy at the time. They are klipsch Chorus speakers. 15" woofer. Horn mid and tweet. They were and are extremely good speakers. They were sold for home use, but similar speakers were used in movie theaters. They had like a 97db effeciency I believe. Amazing dynamics with every little micro detail beautifully communicated. Of course, they did have a touch of the horn sound to them, but still a very fun speaker with a great sound. Giant boxes. Mine were black. I purchased them new for $1300 and that was pretty expensive back then for speakers.
EDIT: Make that 101db effeciency. Just read the specs on the Klipsch web site..
