All numbers are calculated

NS 12 D1 = 85.19

NS 12 D2 = 84.28

NS 15 D1 = 88.47

NS 15 D2 = 88.16

1w/1m figures = not very useful for a sub-woofer

i had a pair of Audiopipe 15"s with a sensitivity rating of 98dB/w/m! on paper, it looks nice.. real world performance was abit lacking.. for a sub, it doesn't say much..
