I recently acquired a RX Jr... I really want to run it through alnico speakers but one problem... The 2X12 cab I have with alnicos (Gold and Blue) is a 16 ohm cab and the RX only has 4 & 8 ohm outputs.
That being said, I’m thinking about getting another cab to run with the RX, but at 18 watts, I’m wondering if a 2X12 may be “too much” speaker. Would it be smarter to get a 1X12 and put a gold in, or should I just get another 2X12 with a Gold and Blue?
Forgive my ignorance, I’ve never run into this dilemma as I’ve always ran 2X12 cabs with 30+ watt heads.
I might add that I only buy used... And there’s an empty Dr. Z cabinet Clone in Reverb for dirt cheap. And I could add the speakers for about $400 used. Where’s as the used 1X12 I see on there is $400 shipped OBO, and I’d end up spending $200 on the one speaker...

You really can't have "too much" speaker for any amp in my experience. I've run 412 cabs with 8 watt amps. It only made them sound bigger. I'd say the Rx jr can easily handle a 212 with a blue and a gold. If it were me, the first thing I would do is run the Rx jr into the 212 16 ohm cab you have and put it in the 8 ohm tap. You likely won't notice any difference between that and running an 8 ohm into the 8 ohm tap. Some folks like a mismatch and it won't hurt the amp at all. Or you could rewire the 212 for 4 ohms, and run out of the 4 ohm tap. I'm assuming the 16 ohms is running two 8 ohms in series. Again I don't think you will hear any difference. Heck, you can even run the 16 ohm cab out of the 4 ohm without hurting the amp. You might with that get a noticeable decrease in power, but the Rx jr is a loud amp and it might not make a difference. I'd try all those before spending another 400+ dollars. Unless you just want another cab, which I can understand completely.

Marc is right. I ran my RXJR head into a 1x12 Greenback last night. 8 ohm tap to 16 ohm speaker. No problems at all. I'd say hold tight with what you have for now. No sense buying the same speaker you already have just to put it in a different cab.
Three ideas I would throw out....
#1 You could look at rewiring your current cab to parallel, which would give you a 4 ohm load. Simple (and free) fix, and lots of diagrams online to help.
#2 Install a switch or some sort of relay to run the speakers individually. Avatar has more complex ones like this for sound $40. avatarspeakers.com/shop/parts/guitar-input/ I recently did something like this for cheaper. I have a 2x12 cab with a blue/G12h30. 16 ohms speakers in parallel at 8ohms. I installed a simple switch to split the parallel connection in my cab. Now I run can the speakers together at 8 ohms, or run each speaker individually at 16 ohms. Bonus....it basically makes it a stereo cab if I ever want it, or could simple run one speaker to keep stage volume a little lower.
#3 Find a cheap 1x12 cab with a G12H30 Anniversary (or Avatar Hellatone 30). Put the Gold in that cab, and put the G12H30 with the Blue. Blue/G12H30 is a great combo and gives you a ceramic flavor you don't already have. Then you have an 8ohm Alnico Gold cab.
