What are the current useless terms in this "audio world"

JS Smith, I think you forgot one... grainy.

  It use to be that an 18" subwoofer could not delineate the upper bass very good because it was to big (hence slow)-- it couldn't come back to it's starting point 'fast' enough to transduce the next note.
Because of that 'pitch definition' was lacking.  Seems fast is ok...

Yes , gobsmacked. Thanks Roxy54 

"Trust me..."  Following a load of nothing but highly perfumed manure masquerading as perceptive, personal insights.

"You'll thank me..." Following another load of manure dressed up as an authoritative statement negating any contrary facts or opinions.

oldhvymec, Where do you live?
