the box is .50 cf aprox. with external ports its going to be two 2 inch pvc ports ported to 43.9 hz.... im going to be experimenting with tuning and the sub is placed in the left corner of the box
ive done at least 127 db with two in a abc box on 280 rms at 43 hz chamber 1 35 hz chamber 2 45 hz....now I want to see if i can do 121 db with one in a regular ported box while being able to play 38 hz and up....this tangband has a 38 hz fs the old ones had a 35 hz fs
