No, They use what they call a "Hybrid Resonator" design.
From the 4x10 specs on Barefaced site:
Hybrid Resonator Enclosure
Efficient 10" speakers like to either be in smaller sealed cabs or larger ported cabs. The downside of small sealed cabs is that although they feel nice and tight in the lows, they tend to sound a bit thin unless you use a few 4x10"s at once or stack them with more bassy cabs - plus they don't handle that much bass power before distorting. The downside of the larger ported cabs is that they're rarely large enough, hence that somewhat boomy bass you get from many ported 4x10"s.
Our unique Hybrid Resonator Enclosure has the tight punchy feel of a sealed cab but with greater bass weight yet none of the boom of an undersized ported cab. The broadband resonant loading of the woofers reduces cone excursion and increases cab sensitivity, which together increases the maximum bass output by over 50%.
