breezefromtucson Posted February 19, 2019 Report Share Posted February 19, 2019 WOULD LIKE SOME INFO ON HOW TO HOOK UP MY STROMBERG CARLSON RS-406 SPEAKERS. 4 POST ON THE BACK MARKED W M T C , WHAT IS POS AND NEG? Link to comment Share on other sites More sharing options...
dxho Posted February 20, 2019 Report Share Posted February 20, 2019 I had some 406s. As I recall, they only had a two-terminal plate on the back. Your looks like woofer, midrange, tweeter, and common. Link to comment Share on other sites More sharing options...
breezefromtucson Posted February 20, 2019 Author Report Share Posted February 20, 2019 THANK YOU, HOW DO I WIRE THESE SPEAKERS, COMMON WOULD BE NEG, BUT ARE THE OTHER THREE POS? Link to comment Share on other sites More sharing options...
dxho Posted February 20, 2019 Report Share Posted February 20, 2019 That would be my guess. But it suggests you may not have a crossover wired up, and running straight amp power to the tweeter could blow it. My suggestion is to remove at least the woofer and follow the wiring to see what's up. Link to comment Share on other sites More sharing options...
JKent Posted February 20, 2019 Report Share Posted February 20, 2019 Maybe post a picture. I know absolutely nothing about those speakers but if they have separate posts for all 3 drivers, maybe they had an external crossover? Oh. While I was looking around the net I see dxho suggested the same thing. This page has instructions for the RS-506 but I couldn't open them http://www.audiophool.com/MadeInRoch.html This page shows recapping the internal xo on some 406s, so I dunno http://audiokarma.org/forums/index.php?threads/recapping-a-stromberg-carlson-model-rs-406-crossover.668793/ Best advice was dxho's to take a look inside. And welcome to CSP. -Kent Link to comment Share on other sites More sharing options...
genek Posted February 21, 2019 Report Share Posted February 21, 2019 You definitely need to open this up. These cabinets typically used an external crossover that looked like this: https://www.usaudiomart.com/details/649311292-stromberg-carlson-vintage-3-speaker-system-with-crossover/images/1369093/ Link to comment Share on other sites More sharing options...
