Off the 3, I would select the first. For 2 reasons. It is tied for the lowest frequency response of 22 Hz and has the highest sensitivity of 94 dB. A sensitivity of 94 dB means that with 1 watt of power, it puts out 94 dB. The other two subs will need approximately 9 watts of power to put out 94 dB. The 12 inch will play louder than the 15 inch, given that it is used in a proper enclosure.Please give a indepth comparison for these subs which is the best?
