Ralf1e Posted March 7, 2023 Share Posted March 7, 2023 (edited) The challenge is can I wire a 2x 8ohm speakers in one cab both in series to a jack socket to use with one amp (16 ohm output) and in parallel to a speakon socket for an alternative amp (4ohm )output without using switching or will the speakers being wired both ways at once cause expensive smoke. Amps connected one at a time to either not both at once. I should be able to see this but I can't get my head around it. Born too soon I expect Edited March 7, 2023 by Ralf1e typo Quote Link to comment Share on other sites More sharing options...
Downunderwonder Posted March 7, 2023 Share Posted March 7, 2023 Without a switch you are getting smoke. Too late for me to draw you a diagram but someone will. Follow it very carefully or you will get smoke. 1 Quote Link to comment Share on other sites More sharing options...
itu Posted March 7, 2023 Share Posted March 7, 2023 I already see smoke... If your other amp has tube power amp, wire the cab to fit it. Solid state is more immune to load. 1 Quote Link to comment Share on other sites More sharing options...
Dan Dare Posted March 7, 2023 Share Posted March 7, 2023 The problem is that you will short the + and - speaker terminals even if you follow your plan to wire the different configurations to different sockets. Try drawing both wiring types and see. You could break the shorts using switches, but forget to set them correctly just once and it's probably bye bye amp. I wouldn't risk it. 1 Quote Link to comment Share on other sites More sharing options...
Ralf1e Posted March 7, 2023 Author Share Posted March 7, 2023 I will wire it to the 16 ohm in series as that is a tube amp that can do 8 or 16 and the other is a Peavey Mini Mega at 4 ohms with power to spare. Thank you for the help and quick responses. I am not risking switches Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted March 7, 2023 Share Posted March 7, 2023 Wire it parallel for 4 ohms. Tube amps aren't bothered by lower impedance loads than the tap rating. It's higher impedance loads that they don't care for. 2 1 Quote Link to comment Share on other sites More sharing options...
Baloney Balderdash Posted March 7, 2023 Share Posted March 7, 2023 (edited) Can I drive both back and forth from A to B (and back to A) at the same time, using the same traffic lane? The answer is: YES You Can! If you just drive fast enough! But not without causing a car and space time continuum crash...

Bill Fitzmaurice Posted March 7, 2023 Share Posted March 7, 2023 You can in Italy. For that matter it's mandatory. 1 Quote Link to comment Share on other sites More sharing options...
itu Posted March 7, 2023 Share Posted March 7, 2023 3 hours ago, Bill Fitzmaurice said: Wire it parallel for 4 ohms. There's another point in parallel wiring: if the other element happens to break, some of the load still remains. 1 Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted March 7, 2023 Share Posted March 7, 2023 It's also harder to mess up parallel. That's the only reason I can think of for Ampeg using 32 ohm drivers in the 810 SVT. Quote Link to comment Share on other sites More sharing options...
