The Mod12-50 is a ceramic speaker with a Warm, well balanced tone with low end focus. The P12Q is an alnico speaker with a very warm, mid-focused bite and clear bright highs.
Product Reviews
Have used a smaller 10 inch with an Orange Tiny Terror head with outstanding results.
Bought a Dark Terror head and needed an 8 ohm speaker, enter this version of Jensen. Excellent performance, exactly what I was looking for.
