my 8 year old paradigm ps-1000 v3 no longer sounds as tight and controlled in its new room. is it the larger volume space or a deterioration from time and use? do the enclosures loosen after time? driver? can i screw it down again? has technology moved on to create tighter more controlled subs since ive been in the market. research shows this was a midrange sub at best when new. i am looking for all the right behaviors for music first then movies in a 26x17x9 room.
