Based on experience from other sub-500W amps into my own cab(s), no it will not. At least with a four string bass. I am on the verge of clipping my QSC PLX 1804 without "farting out" the cab. And I usually boost the 40-60 Hz range a bit, too. Notably louder than with smaller PA amps or my LMII. What experience do you have?
