User needs help. Can you help?
Can you explain the height, width, and length of the port?
Can you please explain the height, width, and length of the port? I have changed the height of the port to different numbers but the 3d rendering does not show any changes. I don't understand. When I go to view the parts, none of the dimension change. What part of the port does height and width signify?
Deskripsi
I designed this box for 4 pieces of this woofer using WEB. My rules: at 30 Hz and above at max power: reach but not overpass the X-max + ideal power handling, at RMS power: 10 or less m/s vent air velocity at 20 degrees of celsius. With this Vb and Fb the losses are the least above Fb in amplitude response, and still matching my rules. Theoretically this box is louder from 28 Hz and above than any sealed box with ideal power handling, but sounds not so deep and accurate, but in my opinion still acceptable.
