fEarful enclosures were designed by greenboy for do-it-yourselfers. They are not for commercial use.
[edit] earfuls of fEarfuls
fEarful enclosures utilize Eminence Kappalite 3012LF or 3015LF high-excursion neodymium woofers and 18Sound 6ND410 (neo) or Eminence Alpha6A/Alphalite6A (non-neo/neo) (only suitable for 12/6 designs) midrange drivers. fEaRB variants provide larger internal space and lower tunings for Extended Range Basses tuned to F#0 or lower, or for synth bass that goes especially low. Here's a scale comparison of various models:
Also check out subwoofers & bass/drums monitors (thanks to davio for all 3D images and models).

[edit] history
"Here's a little history for you. Back in May of 2007, Greenboy started this thread - http://www.talkbass.com/forum/showthread.php?t=336504&highlight= dedicated to his discovery of the Carvin LS1503 PA cabinet as an affordable, possible 3-way alternative to the current crop of cookie cutter bass cabs being produced by most mainstream manufacturers. The LS 1503 movement gained quite a bit of momentum, and the thread was subsequently split several times. Much of his design philosophy can be found in those pages, and it makes excellent reading for those seeking knowledge on the subject. I strongly suggest going back and reading through these posts, (especially Greenboy's)
in all parts to really get the feel of what he has accomplished.
Then, in January 2009, he started the first thread in this series as he modified dimensions of the Carvin design to accommodate the components that have ended up being the backbone of the fEarful design. (fEarful 1st thread) http://www.talkbass.com/forum/showthread.php?t=508659
I know it's all a helluva lot of reading, but to me, it's been a truly fascinating evolution. A LOT of research and time went into this project, and answers to many of our own questions can be found in those pages. Unfortunately, GB got tired of being challenged by some, as well as tired of answering the same questions over and over again, and hasn't posted on here in several months. I miss his informative, and sometimes sarcastic contributions, and count him as one of my best TalkBass friends."

As I've mentioned before, proto-fEarful designs actually predate the LS1503 threads. My involvement with the Carvin LS1503 came about because my radial arm saw needed a total overhaul and I had too little space and time to pursue what I'd come up with. So when I saw the newly featured LS1503 in the Carvin catalog I thought maybe I could live with less internal driver space and mod the casually similar Carvin cab if needed to come closer to my original design objectives... But even then, the itch was never fully scratched for my low-tuning needs and my "details obsession" (that's where de debbil and god reside, after all!). So later I again looked for a builder for my design - and still later I decided to share that design.
As for why I'm not posting on TalkBass all the time, what's said above is NOT a full or true picture by any means. I would not wish to slight the many people I've enjoyed conversing with, the many people who have often gone on to build fEarfuls (or something related to them). I've been happy also that some have been inspired to learn more on the acoustics and enclosures front. The educational aspect has mattered to me, and so have the friendships. So. Please don't take my off-handed and occasional expressions of exasperation as representative of the sum toto of my feelings. I won't go into my additional rationale for not living online lately. But know I'm diggin' on my fEarfuls as much as ever, and my life outside the box : }
Thanks for the good times, folken!
