The measurements is purelly electrical.
The initial one where made manually with a signal generator, a reference resistor and two DVMs. The second, where made with ARTA/LIMP with my computer/soundcard. The similarity then between, strengthen the fact that the measurement where correctly done.
I am a novice in this measure acivities, and not qualified to state what causing that hugh 20Hz peak. My thought where that the cabinette could generate some sort of woofer resonance generating back EMF?
I will try replacing the woofer with an 8 ohm resistor to see what happend.
Those filter schematics would be very much appreciated :o)
