Mighty Favog Posted July 6, 2019 Share Posted July 6, 2019 So it's not the best of parts. It's only the garage system and, thankfully, Parts Express is not that far away for a whole $22! 😁😁 Quote Link to comment Share on other sites More sharing options...

Mighty Favog Posted July 6, 2019 Author Share Posted July 6, 2019 I swapped out the switches too. Might be lesser quality sound but it's only a garage system while I'm working on some other project (or to annoy the neighbors). But I'd rather be safe(r) swapping them out too. They were only 50 cents each. Quote Link to comment Share on other sites More sharing options...

glens Posted July 6, 2019 Share Posted July 6, 2019 Aren't the polys normally normally-closed across a resistor with a little meat on it's bones? I don't see it or the new polys in place... Quote Link to comment Share on other sites More sharing options...
Mighty Favog Posted July 7, 2019 Author Share Posted July 7, 2019 I didn't see any resistors on this board. Quote Link to comment Share on other sites More sharing options...
BEC Posted July 7, 2019 Share Posted July 7, 2019 Some of the crossover designs have a resistor in parallel with the poly switch which allows the tweeter to continue working at a much reduced level when the polyswitch opens. Some like the KG-4 just have the polyswitch so the tweeter will go completely silent when the polyswitch opens. Bob Crites 1 Quote Link to comment Share on other sites More sharing options...
Mighty Favog Posted July 7, 2019 Author Share Posted July 7, 2019 Thanks Bob. That makes complete sense. Quote Link to comment Share on other sites More sharing options...
glens Posted July 7, 2019 Share Posted July 7, 2019 I thought the reason for keeping the tweeter going through a resistor was to keep from practically shorting the amp at the crossover frequency via the cap and coil in series. Or is the switch between the cap and the bypass coil? Quote Link to comment Share on other sites More sharing options...

Or is the switch between the cap and the bypass coil? There is no bypass coil (coil and cap in series). It's a two-way, with a third order tweeter filter. The polyswitch is before the first cap in the tweeter leg. Quote Link to comment Share on other sites More sharing options...
Mighty Favog Posted July 8, 2019 Author Share Posted July 8, 2019 Can I join the crowd that screams that cap leads are too short?? Quote Link to comment Share on other sites More sharing options...
