Hello here some pictures of the construction of my bandpass per Chassi 6 Liter GG and a 100 Liter vent chamber ports are 3*10 cm pipes 200 mm long
Dear Klaus,

Apologies for late reply. I have been busy and making this project occasionally.
Now they are almost ready. I must say that I’m impressed! I am not going to waste
these subwoofers under bench. I am preparing feets for them and use them at
my main system.
I tested them with Sunfire HRS 10” subwoofers plate amplifier
(it has some kind of Linkwitz transform in it) and these towers play wery low
with great slam and effortlessly!  Very bargain system!!!
