All Jensen® Alnico speaker model numbers begin with the letter P, and are therefore often referred to as the P series. Next in the model number is the diameter of the speaker. Alnicos are available in the following diameters: 8”, 10”, 12” and 15”. Following the size is a letter which traditionally is used to designate the speaker power rating. For example, R (25 watts), Q (40 watts) and N (50 watts).
