45 Hz is going to work for lots of things. -3 dB @ 130 Hz is going to take
an audible toll on lots of things. Given that the medium is digital, adding
bass boost in post to extend response to at least 85 Hz should be pretty
doable, but a PITA.

For that six-figures HDW-F900 price, one would hope for more than 130 Hz low
end cutoff!
