I for one am very happy to hear Paradigm has stepped up to the plate and hit a homerun.
Hey Krisg, that ps-1200 being 10 years old would have been a version 1 or v2. Very mediocre driver with a 130 watt rms amp. I had a v3 which was a 175 watt rms amp but similar sound characteristics. You my friend are getting a brand new v4 with a 200 watt rms amp and from some reviews that I have read, will be fairly happy with this unit.
I have debated with some people that the ps series is a big compromise in sound quality, while being big with its output. And have been told that the new v4 along with its more power does have an upgraded driver over its predecesors. Some people have even come to say that the new ps v4's are now for the first time a musical sub. I personally gave up on my v3 to get the pw-2200 v2 so I have never heard the ps-1200 v4. Looking forward to a review.
P.S. I noticed a sustantial change to my old ps-1000 for the first 20 or so hours of use. Just wanted to know, that while you are using your new sub if you feel that subwoofer break-in is fact or fiction.
