The high power 10” Alnico in the Vintage Series, the P10Q was used in a handful of beautifully sounding amps such as the Tweed Super, Brownface Super, and others. This speaks to the fierce tone of the P10Q, capable of great clarity, detailed tone with excellent trebles, and well supported by a solid mid and bass foundation.

Guitarist Description
Warm tone with some bite in the mid frequencies which translates into a fierce response to overdrive distortion.

I built a deluxe reverb 2x10 combo and loaded a mix of the Jensen P10Q and the P10R together. All I can say is WOW... That has got to be the best combination of alnico speakers I have ever heard in my life!


My Pro Junior sounded muffled and dull, like someone had stuffed the amp in a sleeping bag. I popped out the old speaker and put in a P10Q and it's now like a new amp – much more bright and lively and more fun to play!
