I'll try to remember the name of his speakers and/or company. I did Google it in March, and found information on it, but I'd forgotten about these photos until just now.
This guy really loves Classical music. After introducing his speakers and components, he proceeded to play selected tracks of music. Each track was chosen to demonstrate his speakers' strengths. There were something like 15 tracks. Each showcased different instruments - violin, cello, bass, French horn, flute, kettle drums, harp, piano, guitar, opera, etc. Much of the music was new to me. However, I came away with words like "magnificent", "spectacular", "thunderous", and such. He played "1812" and the cannons were thunderous!
As you can see, these are 4-way speakers. I don't recall anything about the drivers. Actually, now I'm second-guessing my first statement about the 15" woofers. These speakers may have had 12" woofers. I'll have to ask one of the others who were there. He'll know.
