They concluded based on the tests I did that the driver was faulty but I'm not so sure, if they are right then I apologise for the 'rubbish' comment. I didn't want to risk getting another however so I opted to exchange for the pb-2000 which is on it's way.
My room is 2300cuft fully enclosed with fabric frames on the walls and heavy carpet, I use it mostly for movies(6.1) and a bit for music. The pb-1000 didn't have a problem filling the room at my desired volume which is moderate, it just didn't sound very good to me. I did think long and hard about getting either the pb12 plus or sb13ultra but I just can't afford it right now. We'll see how things go with the pb-2000.
Now that explains quite a bit, and why you are unhappy with the PB-1000. A faulty driver will indeed sound like rubbish.
Since you've done everything you could with the PB-1000 … and you sure look like you know all the pitfalls and how to mitigate room modes, I'm hoping you will be highly impressed with the PB-2000. It should provide you with some very impressive bass in that medium size room, and since it is mostly for movies, the PB is a great choice. And yes, let us know what you think once you've set it up.
