Feasibility involves more than technical issues. For instance, your sonic farm alone costs more than either of my heads.
The original question wasn't 'why doesn't everyone think it sounds and feels better' but 'why is it not more popular'. Cost and convenience are factors.
I took my booteek head to several gigs. It actually robbed me of some enjoyment. Singer almost knocked it off the cabs once. Kids, drunks, drunk kids...

Seemed like there was a sign on it that said TRY TO DESTROY ME.
I don't want to sound like one those 'my squier is better than your fodera' guys. That's not what I'm trying to say at all. But I've actually gotten more comments on bass sound since going to the minimega and subway the last few months than I did over the last few years. Probably coincidental.
