For checking the frequency response I have been using:
http://onlinetonegenerator.com/frequency-sweep-generator.html
and
http://onlinetonegenerator.com/
to generate all the frequencies that I need.
I only have a basic sound level meter (£15 from Amazon), but it seems to do the job that I require.
Today my wool 'filling' arrived.
I ordered 5Kg, which seems to be more than enough.
Next week I will take out the last of the fibreglass and keep adding wool until the bass frequency response is much flatter.
