NSD (New Speaker Day) and a dumb impedance queation

[PFDarkside]

I really like my old Princeton Reverb, it's a great amp to get into tube compression at reasonable volumes, and it plays very nicely with my Fenders, P90 Warmoth and Les Paul for the most part. Use a simple boost, OD or Fuzz and the volume control for a simple and versatile setup, or the pedalboard as a great pedal platform.

Recently it seems the stock speaker is starting to breakup more and earlier than it used to. I tried plugging it into the 2x12" it gives the amp more room to breathe and gets rid of the speaker breakup. Of course the 2x12" is loaded with Brit flavored speakers so I was looking for a tougher 10" with an American sparkle and vibe.

Enter the Ragin Cajun. It's late tonight, I can't wait to get it installed and take it for a spin...

Now, here's the back of the amp...

8ohms, cool. But, I was thinking about adding an extension cab from Mojotone to add even more volume when needed. To give the amp an 8 ohm load, that means I'd need to change the internal speaker to 16 ohms and put a 16 ohm speaker in the extension cab. That means I couldn't use the amp without the extension cab.

Am I missing something or is the Fender strategy for extension cabs a little subpar?

You can use the amp without the extension and it should be safe. What you shouldn't do is use 8 ohm speakers in both for a 4 ohm load.

Yes, I'm quite familiar with calculating and matching impedance. It just seems interesting to me that in stock form I'm not sure you could ever use the extension cab jack "correctly". Unless if the idea is to unplug the internal speaker and use one or two extension cabs.

First impressions:
A lot bigger magnet, bigger voice coil so it seems like it takes more power to get the speaker moving at the low end of the volume knob. (Could be cool for home practice) Once you get higher on the volume knob it definitely eliminated the speaker distortion which is good. Overall tone is definitely different than the original, I might have to figure out how to EQ it (and probably get used to it) It seems like more low mids than before, so the strats sound meaty but the tele was a little muddy.
Time to play and mess around more!

I would not hesitate to run your OT at 4 Ohms. 16 Ohms is the theoretical wrong way to go.
Catastrophe (for a tube amp with an OT) is an Open, not a Short.
The bad scenario (with amp being played) is to yank a speaker cable from a speaker cab .....not from the the speaker jack on the amp.
