The scent I was smelling was the insulation / batting, glue, wood, stain, (new electronics?) etc.
My last setup was in a smaller bedroom, sealed pretty well also.
The smell is of new speakers, like a new magazine, car or home. The smell goes away after time or after the environments smells take over, just like your new car or new home smell goes away after awhile.
If you have sealed cabs then you probably wont smell what I'm talking about. I think that the air moving through the cabinet, over and through the insulation and out the port is what I was smelling.
interesting though that no one else has smelled this on this thread.
