I have got a BB2 and I usually liked to add a HPf setted very low (below 32 Hz cut) AND some kind of bass cut at the amp side. This was with a Markbass head, that, contrary to the claims of the factory, has no audible cut at lowest frequencies and, in all honesty, with the barefaced it does produce a woofy confused extended undefined bass. Hate it in fact. The BB2 is deeeep as the ocean, and takes no prisoners in that range. Sometimes I think my personal taste is more towards tigher, less extended low end.
This is valid even in recordings, where i cut beastly at 50-60 Hz with no mercy, and to me it works.
Then I bought a Peavey Tour 700 (great built in HPF) and lately a Walkabout (very all tube-like hybrid). The BB2 reproduces the huge bass of the WA but the sound quality is way higher and I find myself liking it as it is. Maybe inddor I will still use some kind of HPF and or bass cut, but outdoors in another thing.
Since I got the BB2 I became fond on the idea that having a super deep cab is not my cup of tea, but i found this principle was true for some SS or class D heads. A slight amount of tube grit and natural tube harmonics of the WA compliments beautifully the badass bass of the amp + barefaced producing a huge but defined tone. Surprisingly, I found that the cab sounded quite bad with tube grit and the high frequency driver completely off, while adding the horn yelded better results to my ear...I know that the "super" range of barefaced cabs has been built for immediacy and hi-fi tone, but in my esperience a good tube tone sounds ok trough a BB2. I always used the HPF for tonal purposes only, the barefaced can safely take big bass all day long and in fact i think i never even touched their excursion limits.
