An old cab that I sometimes use for practising has a 12" guitar speak in it, it sounds fine with a bass through it (it is a proper ported bass cab...)[/quote]
The frequency of a low B on bass guitar is about 31Hz, thus it's important to have the correct speaker / cabinet to be able to reproduce this with any kind of 'volume'.
