Actually, after auditioning this sub in PR I would buy this before the Fathom (in terms of value it is a better deal):

I am pondering separating the plate amp from the box and putting it in an external chassis, away from the jumping bean. Would need to have a blank plate machined in 1/8 stainless steel, would probably be expensive and only make a minimal difference, but it does sound like a fun project.
I am waiting for Anders et al to share their take on how to tame auto on. I am thinking an infrared detector that senses when I am in the room and turns it on a set minimum time using a 555 circuit or better yet, until I tell it to revert to off. That or Anders could tell me what magic condenser or resistor or rheostat or peaking coil controls the sensitivity. That is what a brother would do.
