Infinity Column II
Three Way Loudspeaker System (1977)
A high-efficiency speaker incorporating new developments in driver technology is Infinity's Column II.
To add spaciousness, one of its two piezo electric tweeters faces the rear. These specially developed, remarkably clean sounding tweeters, unlike other piezo electric devices, use no horns, but act as direct radiators.
To prevent interference from the woofers, a new 10 centimetre midrange driver is sealed in its own sub enclosure.
To provide excellent transient response in the midbass range, a 25 centimetre woofer utilizes an unusual low mass radiating element. To couple bass output to the room, a 25 centimetre subwoofer faces downward, near the floor.
Radiating area of the two woofers, configured in what audio engineers call a dual driver staggered resonance system, is 60% greater than that of a single larger 30 centimetre woofer.
Column II can deliver plenty of bass and plenty of power, without the roughness and midrange peaks typical of many high efficiency speakers.

I bought these at an estate sale. Had listened to them back in the day and was very impressed.At the time(I was a senior in college)and could not afford the $1200.00 price. The sound is outstanding and if you get the chance to buy don't hesitate.

I simply have not known of another that can take the beating these do and still impress everybody with the clarity. Woman love the sound, musicians talk about hearing all the background and to me they always sooth the beast. FIVE years out of warranty Infinity CA sent me TWO NEW mids. When I called to explain I could not afford them she said just enjoy. About eleven (11 !!!) yrs out of warranty I called Infinity CA to find out about foam kits....yep within a week I had a box arrive with FOUR NEW POLY WOOFERS! I never have written but told anybody at any chance about Infinity and how they treat...funny word TREAT their customers. Who she was I protected. Now is the time to let the world know what used to be and is one very very special Lady! THANK YOU sweetheart and thanks Rich Reed for giving them to me in 1979. ( He melted a few bits that Infinity also sent me!)
