So that's where the bass had gone

After plenty of hard driving to get my system run in I was merrily enjoying some great bass playing on various albums on Saturday (sounded pretty good 2 floors down I was told) but was curious to note that a strange addition to the bass guitar at high volumes, a slight buzzing. A quick investigation of the speakers showed a couple of loose (I mean finger loose!) bolts. Out with the allen keys and wow! Suddenly some serious control over the bass, it was sounding pretty good before hand. Now the question is what is the ideal torque on those bolts (BW N804)?

A happy listener.
