Music in the 40-80 Hz range

I've been low-passing at 40 Hz with a 24 dB/octave slope to a pair of Velodyne HGS-10s, because the 3 dB down point for the KEF Ref 1s is claimed to be 45 Hz.  Yesterday I inserted a passive fully balanced 80 Hz high-pass filter to shunt frequencies below 80 Hz to the subs and raised the low-pass to 80 Hz, both 24 dB/octave.  But I wonder if it might be preferable to have the 45-80 Hz range reproduced by the speakers rather than the subs.  How much music is in this range?

Advice sought.

More LF sources is better. Each LF source creates its own room modes depending on the frequency and location of the source. The few big modes you get from one sub won't sound nearly as smooth, fast or good as the many small modes you'll get from three or more sources. Try it and you'll see.

There's actually quite a lot of music happening way down low, its just that its so hard to reproduce well. Until I got my four subs I had no idea how much.
