sub, I wouldn't count on it without actual measurements.
Overall max output at what frequency range?
Typically two sealed drivers will best one similarly sized driver in a ported box or a sealed box above 40hz because of the added efficiency of the second driver. Up there, the ported sub is unable to take advantage of help form the port. The dual sealed sub becomes in effect two subwoofers just simply sharing one box and one amplifier, as long as the box size is double what you would normally place one of the drivers in.
However, assuming the ported sub is tuned to 20hz-25hz then it will have a distinct advantage around that frequency, usually 6-10 db over a single driver sealed sub.
However if you look at the measurements from Ricci on the PA-150, output falls below 40 hz and decreases rapidly below 30hz. much in the way a sealed sub often would.
My guess is that driver would have needed to be in a larger box to get flat output lower and achieve results typical of ported subwoofers, which often can solve "lack of boundary gain" issues in larger rooms.
However it's output above 40hz is still impressive.
I recommended a pair of PA - 150s to a good friend about a year ago based on his needs and tastes. I helped him set them up. He didn't really care about bass below 30hz and he was on a budget.
The PA-150 filled his room nicely. Having experience with them I would say our 200w model is actually somewhat similar in overall output giving the PA 150 an advantage in output around 30-35hz.. Our 300 watt model would be a closer race.
The Premier unit however is a really nice unit for the money.
I could not find fault with anyone choosing it on a budget.
