Thanks! I have trouble measuring the sealed sections tuning frequency.
My impedance meter shows that the box seems to be a ported box, so i think that the port is already too small (read: i have no port on the ported side).
I think i need to drill hole through the sealed section and put TL sensor inside it to find out the resonance freq of the sealed.

Project continues with the doorpanels.

Door panels look crazy!

If you have the ts parameters of the subs and know how many litres the sealed section is there is a formula you can use to calculate the Fb.

Impedance doors closed.
Lowest Freq between the peaks is 53Hz and doors open its at 40-43Hz.

here are drivers parameters.

sealed section is ROUGHLY 450litres.

Mids and high amps are in.
Next... amp for subs

Started to make my doorpanels

I like my tweeterpods, ALOT

Got first sounds!

prety impressive frontend, 4th order starts from 25hz peaks at 36 (doors open) 48 (doors closed).
did a little burp with 700W, 145,81dB @ 48Hz.

Cannot play any louder in the neighborhood...
