Speaker - Jensen® Vintage Alnico, 12", P12Q, 40W
The P12Q is a lower power sibling to the P12N, with a smaller voice coil and a vintage steel basket, nicknamed the “hot dog” or “sausage” because of the shape of the openings in its basket frame. Warm and balanced sounding, with a nice bite in the upper midrange, it is a very interesting allrounder, for many different applications from the traditional country and jazz tones to the more aggressive rock and roll and blues application. Typically it was found in ‘holy grail’ amps such as the vintage Tweed Deluxe and other similar models as well as the Ampeg® Jet, Gibson® GA-20 and many more.
Guitarist Description: Very warm, mid-focused bite with clear bright highs. When presented with overdrive distortion it remains well balanced.
- Lows: Loose
- Mids: Firm
- Highs: Smooth
- Overdrive: Edgy

Ideally you want the wattage of your speaker to be as close to double that of your amp. If you will be strictly playing this at low volume (below 4 on the volume dial) then it should work. But if you plan on cranking your amp, you run a good chance of blowing this speaker.

Will this work in a Vox AC30?

These would be a nice option if you are trying to get more of a vintage American tone form the AC30.

Came across a vintage, 1959 P12Q for sale...was considering it for my '63 15W Gibson GA-8T...is a 40W speaker too much for that amp to hit it's "sweet spot" (i.e.overdrive the speaker/cause it to breakup?)

The answer to this is subjective. 15W should produce enough power to get some sufficient air through the speaker, but may not be enough for some player's personal tastes.
