12.5 MM of Xmax = almost no bass.
I lol'd. It NEEDS to be able to handle 1000 watts of power to make any sound...Sensitivity 1W / 1M 84 dB 83.5 dB 84.5 dB 85 dB
The LMS-R's are not as low, but still not great but at least they have some excursion to them.
Trav:
Since when did they start making the 15?
And those are SQ subs, not SPL.
You wanna try the axis if you want SPL, but its even more money again.
