Truly awesome effects from cabin gain. Especially in the teens and twenties.

yeah my car has a huge peak starting at 30hz and down then it dips then another around 40-45hz. Until I started to get my cabin gain results I could never get anybox to sound right.

When did they stop getting their magnets from china? Really made in The USA means nothing anymore. Get what you like where it's built means nothing.

Maybe there magnets. But there site says. NEW FOR 2011, ALL STEEL MACHINED IN HOUSE AT FI

Well i know most everyone says Fi is a good brand, and i saw several ppl talking about the SSD. I also messaged a guy who has ran both 12SSD and SA12, he personally preferred the SSD. But its highly recommended, takes 2cu to sound good, rms is 1000 and its only 15more then sundown. Plus not alot of people have SSDs

In my van i have a big peak @ 40hz. I can eq it out but I don't completely remove it, I like the sound. Cabin gain does different things in every car, so until you measure yours you just don't know. How ever most people don't worry about this... and get boomy bass. Sealed subs have the advantage in this case. But they don't go as loud. Often you would need 2 sealed subs to equal one ported.
