Sure!
As far as I experienced the flared ports have a much more severe turbulent flow separation and "resonator unloading" characteristic. So once the flared port compresses (or, more precisely, flow separates, the resonance is lost, driver excursion is multiplied) most of the output is lost.
Tubular ports start chuffing and (mildly) compressing earlier, but the air flow is not disrupted completely.
My explanation is:
The flow disruption of flared ports happens in the port flare. With tube ports the turbulent flow stays more outside the oscullating air of the port.
