The Oxford speakers are known as relative inefficient speakers (not loud) with moderate bass response.

With a 10 inch speaker run by a 12-15W dual 6V6 amp, it delivers a true “American” Fender tone with punchy, responsive lows together with chimey highs.

The vintage Jensen C10n Princeton Reverbs are rare and during the silverface era most Princeton Reverbs were equipped with the Oxford speakers.

If you have one of these you’ll experience a significant change (to the better, in many’s opinion) by swapping to almost any other speaker.

First in 1978, when the push/pull volume boost was introduced, there was a significant difference from the traditional blackface circuit. Due to its small size many players want to increase the power, volume and clean headroom.

A few also wants to change the distortion characteristics. Just because many people does so, it doesn’t mean it’s right for you.Still, many people consider the tone of the silverface Princeton Reverb just as good as the blackface.Being almost a blackface amp with a “wrong” faceplate, the large number of silverface models became popular player’s amps. As a player’s amp one could replace the speaker with a bigger one without “ruining” the value of it, like for the precious collectable blackfaces.By most guitarists the Oxfords are considered weak and they fart out in the lows when being pushed hard.Because of the low efficiency you’ll have to turn up the amp and push the tubes harder to get any volume.We’ve seen no other amp that has been analyzed so thoroughly in terms of mods and tricks to make it bigger. In general we don’t recommend the mods that increase the power and clean headroom unless you actually have experienced the amp to be too small at gigs.
