Super super.first time I am hearing Fourth Order Subwoofer. I have Klipsch Entry level 5.1 speaker set connected with Denon 540BT 5.2 AV receiver.. that Subwoofer is set to down fire and as you said vent is fixed in the back side of box..
I am bass lover esp smooth bass I love very very much.. those 80's I used to lhear bass from car.. so wonderful.now I am getting same bass effect in my Klipsch subwoofer
Semma explanation bro.. I am using 4th Order Box.. Which is good in Boom bass.. If you want i can share you some sample video's. So that you can show the difference to the audience😊
Sealed box volume is 1 cubic feet. Ported box volume is 1.75 cubic feet. 4th order box volume is 1+1.25 = 2.25 cubic feet. Sealed and fourth order boxes are not same in size.
