Popular Science's Feb 1957 Speaker Roundup

These tables are from Popular Science, February 1957. They accompany an article about basic speaker properties and selection; I didn't feel it was important enough to scan. The article draws no conclusions whatsoever about the relative performance of the speakers.

Most of the manufacturers are big names, but I've never heard of Quam or Stephens Tru-Sonic.

My apologies for the file quality of the first two images; the maximum image size here on AK makes the tables pretty hard to read. The much higher quality original 300dpi scans, in color, are at http://cs.oberlin.edu/~hbent/psscans

Quam were generally replacement speakers, pretty generic.

Quam is/was an old company. They made drivers for a lot of companies.
 
I don't think that one is particularly valuable... I am going to put it in my single Karlson K-15 cabinet, where I expect it'll be very happy.
 
Mr Stephens was an understudy of Dr John K. Hilliard, as were a couple fellas by the names of James Bullough Lansing and Jonas Renkus.

You can be sure that most of his products were born of the same ingenuity and excellence as those of his peers.
