Like OP, I am a Legacy owner and wish more were posted about them. Obviously, they are indeed large and heavy, very big footprint, hard to pack, and nearly impossible ever to ship for sale or trade. I use the Signature SE because I would need 9' ceiling for the Focus. Bought them because they are fully enclosed, no port, not sensitive to placement, and they go lower and flatter more naturally than anything else in their price/size range. They are also US made and provide good advice on fine-tuning for the customer's listening environment.
That said, being designed with a peak at 35Hz and a steep rolloff below, the Signatures (including Focus) still need subs for the (to me) essential Octave Zero.
Now, as for the decline in quality of posts, censorship and the rest -- I don't know the story and can't comment except to say that I miss several very useful commentators who were once here and now departed for reasons unknown to me. (I had assumed that maybe MC had been shamed out by the Kevin Deal Raven demolition, or that maybe the overt Tekton flacking was deemed too brazen, but just guesses on my part. Never saw OldHvy, etc, doing inappropriate salesmanship, political ranting, threats, etc, so no idea why he and others named are no longer to be found. Nor why whole threads, rather than simply individual offending posts, would be taken down. There was plenty of useful info in some of those deleted threads). Oh well, somebody needs to make the rules, so we freebie users need to take it as we find it.
