That depends on the speakers and the enclosures.

All else being equal, that speaker has a sensitivity rating of 86 db.  So at a reference distance of one meter, one of them with 400 watts will produce approx. 112 dbSPL.  Two of them with 175 watts each will produce approx. 111.4 dbSPL  The difference to your ear is insignificant.
