Ok guys.... lets take this down a notch....
The Audio world and sound is extremely subjective from one person to the next... Not every speaker or sub is for everyone, and everyones ears are made differently... Some peoples ears can't handle what the next persons does...
Lets take for instance... RMK! is selling off all 4 of his JL Audio subs, 2 F112's, and 2 F113's, and while some might view his decision as being totally off his rocker, he is on a journey to find what subs work the best for him...
Now I am on the side that says he is totally off his rocker...

but its his setup and his ears that he is pleasing, so who are we to say what is better sounding to him...?
In my journey of spending money on products, I have found that I prefer sealed over ported over the years now, and if I need more sealed subs to reach the depths, where ported has been shown to be more efficient, then so be it... I will build more subs... I have 2 - 18's and 2 -15's lined up all for sealed builds, and I'm am pretty confident I will be happy with the results.
If they sound anything close to the JL F112 I have, I will be thrilled.... I have a feeling they may just surpass it... but in the end.... All this is really just subjective...
