Howdy folks,
Figured I’d tell my fEarful 12/6 build story for all the noobs (like me) out there. I chose to go with the simplest system. No tweeter and, although I was tempted by some of the other mid drivers (faital, 6ND410, etc.), I chose the alphalite 6A mid driver since it has the simplest crossover (here).
Main items I bought:
a cut kit from swift
3012LF speaker from speakerhardware.com (~$30 cheaper than most other places)
alphalite from partsexpress
crossover components from erseaudio.com (note: some items were listed as out of stock but still shipped to me immediately)
Initial box assembly
I printed out a few choice thread entries and diagrams from the fEarful wiki to get an idea about assembly order. Dry fitting the kit (clamping together without glue) was very necessary. It helped me understand how the kit fit together. It’ll also show if a little trimming is needed.
So, I started by gluing/clamping the mid-driver box (side and bottom only) onto the back of the baffle, the spine and sidewall supports on their respective walls, and the port divider to the port shelf. I used green label titebond ultimate ([Invalid or Expired Link Removed]) (NOTE: this glue dries pretty dark. i think the red or blue label varieties might dry a little lighter in color) . The mechanical drawing of the system (Link Removed) was very helpful. I thought about trying to shift the port shelf back a bit to accommodate a grill cover going all the way down to cover the port, but decided to stick with the standard plan this time.
Dry fit (aka, "oh, that's where that goes"
)
thank you harbor freight
I measured out the placement for the braces (rear and sides) as accurately as possible so they'd line up together when assembling the whole box (EDIT: there was still some misalignment which required trimming later). After laying them out and measuring, i drew a pencil outline for where the brace went. Then I glued and clamped.

I've used books, bricks, weights, 1/2" steel plate...whatever is heavy and won't roll.
(thanks foz) i liquid-nails it up and let it dry overnight. this morning i reinstalled the mid speaker and it's much better. i only played it for ~60 seconds but i think it's fixed. i'll try to put some audio and final pics up soon.
