Hi Everyone, I've had these around for some time and thought I might be able to put them to use but can't find any hard data on them. I ran the tests to determine the TS numbers and found that they are different. I suspect age has caused the change and one either has a more supple support structure or the other one that is more rigid. Ideas on getting them to match are welcome.
TS data
Speaker A / Speaker B
Fr 28.4 / 41.0
Qms 6.46 / 10.85
Qes 0.40 / 0.87
Qts 0.37 / 0.80
Re 5.8 / 5.8
They are 15 inch co-axials. They came from Lafayette Radio/Electronics sometime in the 60's or 70's. The only number is 21-47254W on the baskets.
LRE had some from several manufactures I believe incl Goodmans, Jenson, Utah. A web search didn't turn up anything in this size and configuration.
