Morel Utimo 12 frequency response: 10-900 Hz.


JL audio W7 is designed far better than that morel even. some claim the W7 can do 6 Hz, and I think I might have personally achieved that at one point when I had my 1000/1 amp before it got ripped off. it was like an earthquake. I also entered a Db drag race and hit 135 something Db with that single sub. I wouldn't expect the morel to have that kind of excursion because it isn't hitting that low. I doubt it could do the 10 like it says if it has that much excursion. or is it simply the LINEAR excursion its capable of? that is seriously a point to consider.

anyway what you need to achieve SQ is mainly a sealed enclosure, high power, and the ability to accurately reproduce all the recorded sound. if you are missing a chunk of the spectrum, do not expect to have full SQ. look up the 6 patented technologies used by JL audio, and you will see why they can be still considered the best in the world after over 10 years. things like patented technology and linear excursion are things you want to look at for sure when judging the performance of a woofer.

for you to claim that 15 Hz and excursion doesn't matter when you list the Morel Ultimo as the pinnacle of vibrating cones hits 10 Hz? then why cant the lighter, more rigid patented W-cone do the same? in order for them to achieve the specs they are rated for all angles of the woofer must be looked at and engineered for the best performance making it naturally the best SQ available.
