PB1i vs OB1i, worth the price diff?

[jaxwired]

I love PMC speakers. I think they have world class mids and imaging to die for. However, I also think they are over priced. When you compare the fit and finish of even a B&W PM1 to the PMC PB1i at 4 times the price, it's no contest. And why the crazy price jump from OB1i to PB1i? I mean, the OB1i is already very steeply priced for what you get.

But, I digress. I know the PB1i has an extra bass driver and 4 extra hz of bass. And I know that the bass drivers are different, but the mids and tweets are the same and the box is very close in size to the OB1i. Yet it's priced like 50% more than the OB1i. This seems crazy. Anybody think the PB1i is really worth all that extra doe?
