Vintage Radio Shack Woofers Tweeters Minimus 7

[Raulduke]

I was rummaging through the attic and came across an old box of speakers. They are all new in original box and look like they are in good condition. I took out out of the box and they are stilled wrapped in plastic. The cones are all in great shape. I believe these were the original woofers used in the Minimus 7 line. Here's what I have. In terms of price, name one I'm flexible, would like to see these go to good use.

3x Realistic 4" woofer P/N 40-1022 B
2x Radio Shack 4" woofer P/N 40-1022 B
2x Radio Shack super dome tweeter P/N 40-1276 B
1x Radio Shack Horn Tweeter P/N 40-1377

I can check to see if that cross-references with the ones i have... with a spare set of Minimus 7 boxes i may well be interested.

RS MINIMUS 7:

For models 2030A, 2030C and 2034A the woofers were
SP5411
SP5412
XB1744
S4701
S4702

The woofer you have may fit but was one they sold to the public. Gimme a few more minutes and we'll see if they match.

Don't be fooled by the difference in power rating between yours and the Minimus 7's, the original woofer was a 10W max. also IIRC .
