the 12" are more efficient than the 10". reason why they all use 10", because you can stuff more 10" than a 12".Originally posted by denim Havent you ever wondered why Alma, Micheal, and the other Kicker sponcered peeps run the 10s..?? They have all the capibilities of the 12s in a smalled package...better for mounting them side by side, The 10s may have less cone area but for some strange reason thay are better for spl instals, from pix of the 10L7 and the 12L7 side by side....the 10L7 is just as deep.....it has a much larger surround.....6 sqin more cone area than my Shocker extreme 12s.......the magnet is 3/4" wider and almost 2x as tall as the mag on the 12L7....and the dam thing is heavier.
the 10" is rated at 600 watts RMS and the 12" is rated at 750.
(14) 10" will have about the same area (1400 square inches) as (10) 12" (1440 square inches)
(14) 10" =600watts (14 subs)=8400 watts RMS total
(10) 12" =750watts (10 subs)=7500watts RMS total
