Members ksl Posted April 4, 2023 Members Share Posted April 4, 2023 Greetings,,, The Marshall plate pictured, is what I want to end up with (w/o the series load option, only parallel)The other plate is mine, with each 1/4" input going to one of 2 16 ohm speakers & I'm trying to figure what my double throw on/off would need to do to make this DIY happen?? Or should my initial wiring be the parallel connection, & then get the switch to do whatever...?I want only MONO (8ohms parallel), then 1 left & 1 right speaker for stereo ops.Many thnx Quote Link to comment Share on other sites More sharing options...
Members Djangler Posted April 4, 2023 Members Share Posted April 4, 2023 Try this. If you want completely independent stereo speakers, change S1 to DPST to interrupt the ground connection between the speakers. Quote Link to comment Share on other sites More sharing options...
Members ksl Posted April 4, 2023 Author Members Share Posted April 4, 2023 (edited) cool,, in this diagram, what is S1 as it sits? Looks like it is connecting the 'hots'...? I thought i had done this exact set-up, but i couldnt isolate the left from the right & vice versa....thnx Edited April 4, 2023 by ksl Quote Link to comment Share on other sites More sharing options...

I thought i had done this exact set-up, but i couldnt isolate the left from the right & vice versa....thnx Yes, S1 connects the positive side (hot) of the two speakers to put them in parallel. The negative side (ground) is always connected. This assumes that the two "stereo" channels come from the same amp so they have the same ground reference. If you're using them with two amps, get a dual pole switch and add it to the connection between the negative sides of the speakers. Remember, if the two speakers share the same speaker cavity, there will be acoustic coupling between them. If you play a tone in one speaker, the other one will move in and out too because the air inside the cabinet loosely ties them together.
