Any chance they're out of phase? Maybe the terminals on one speaker were wired backwards. Compared to the hassle of sending them back, it's worth reversing pos/neg on one speaker to see if the bass shows up.
Of course you may already have done that.
Since those woofers are commercial-grade units with pleated surrounds, I wonder if they demand a longer and vigorous break-in. Those should have bass out the wazoo. But "should" and "is" are two different things.
