This is still a two-way speaker, although it has two bass drivers (which
only gain 5 Hz compared with the F20). So it also should be combined
with a subwoofer.
Frequency Range ( ±2dB ) 55 Hz - 20 kHz"

I have a pair of F30s; I also have the Celestion S80 powered subwoofer.

Unless you are listening at very high sound levels, you won't need the
subwoofer for music with the F30s, just boost the bass a little to
compensate for the speakers' rolloff.

With the subwoofer level set to sound OK on DVDs, I find its better to use
some bass cut for listening to quite a lot of music.
