PRS Archon 25 speaker connection question

[jdcrossroads]

I have 2 celestion 8 ohm speakers. Ive installed a vintage 30 8 ohm speaker and set the ohm selector switch to 8 ohms . I installed the other 8 ohm speaker in a cab. What should the ohm selector switch be set at with both speakers plugged in?
Thanks

If your amp makes those two speakers parallel then you'd need/want 4ohm selection.

Thanks. So i dont have extension cab plugged in i would select 8 ohms, correct?

Not sure about your combo. Is there a sticker/printed info near the second speaker jack? If it was a series connection then you'd need 16ohm

It originally had a 16 ohm speaker and had a 16 ohm sticker on it. Im pretty sure their parrallel though. It has a switch for 4,8,16 ohms.
If parrallel,
4 ohms setting for 2 8 ohm speakers
8 ohms setting for 1 8 ohms speaker?
Thanks for your help!

Yes, that looks right. My Custom 50 combo has the same switching. I have the original 16ohm speaker in the 1x12, and had a 16ohm 2x12 with it so in that config I had the switch at 8ohm.

Perfect thanks again. Btw this amp really kicks butt with an extension cab!
