What type of / brand of mic are you using?



I was not trying to make a very accurate measurement so I just used a
cheap Panasonic WM-60AT price £2

Actually, this mic is known to be very accurate within the audio range. It's
major disadvantages are that it is a raw capsule with no supporting hardware
or circuitry, it tends to clip at moderately-high sound levels, and it has
questionable noise characeristics when used to pick up low-sound levels.
Your application seems to finesse these issues so it remains a good,
accurate mic for the application.

The Behringer ECM-8000 is arguably the next step up for under $40 in the US.
It is a finished microphone and has better performance at high sound levels
and w/r/t noise. When used for woofer measurements, it does have a
documented roll-off below 40 Hz that can be easily compensated for.
