i would love for you to share this info with me as well if you could

i have the same baffle> came out of a wall in a local buffalo theater> the baffle has exactly or almost eactly what you have. i was wondering what kind of enclosure as well

HI did you still want some info on your University Sound speakers? My Dad and I know some about these speakers, drop me a line if you’re interested. Cheers!~ Bellarmine

I bought an Eico ST40 amp kit built it to specs in mid 1962 and bought a C15W along with a MF1 horn and Sphericon tweeter including the crossover/L pads. I took down a single clothes closet door and braced it on the inside and installed all the speakers in the door and screwed the door to the framed opening and sealed it (closet was the infinite baffle enclosure). Without getting into all the installation work I fired the system up and dam it to hell it rattle most all the windows and kitchen cabinets in the house. Neighbors had no words for it. I had a Bogen turntable with an Empire 880P cartridge plugged into the Eico amp and it was a heck of a system. I later made a clone tonearm similar to the Ortofon arm out of tube of aluminum along with a glinbal piece and it tracked well. Still have the C15W and the HF1. In Jan 64 I went into the USAF and carried everything with me except the closet. Set the system up in my room in the barracks. Most all the guys gathered around when I played music with it. Never forget them days. Im still messing with stereo systems today. I have Carver amps and pre amps along with Audionics , Sansui.

I’m told that this configuration of pairs happens quite a lot.

What’s up with that?

By the way, I paid $60 for the pair two months ago and today somebody turned me on to a single 315c up in Canada for 450 which I promptly bought…
What is the non c worth?

Actually the reason for the smaller speakers is due to the cost of manufacturing. Basic acoustic physics demonstrates that several things are required to produced sound for music. Avery Fisher and Henry Kloss selected 12 inch as the ideal compromise. Then came the matter of the size of the magnet, the larger and design of the cone was relevant based upon the size of the enclosure. They then dveoped the “bookshelf enclosure” using heavier magnets to offset the size of the enclosure with great success. Acoustic or Bass designs were the most common. However in 2020 we have advanced prosumer speakers, but the goal was and remains to actually reproduce the sound. It is fun to alter with treble and bass (loudness control) controls to achieve personal satisfaction often totally different from being at the actual performance or recording studio. I have a pair of AR3s in exc condition and a pair of 1970s Fishers. What is fantastic now but unavailable then was the excellent electronic components we use to literally crossover the bass with (often midrange) abd treble speaker to achieve sound quality unavailable even in the 80s. Good speaker sound remains subjective but still requires intelligent manufacturing with quality choices. Vinyl is no longer for the fringe and is bringing back the need for hearing the wonerful nuances of analog sound.
