Enclosure
Vented, Vb: 5.9l, Fb: 41.1Hz
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?
Description
Compact vented box for 2 pieces of this woofer: lowest possible Vb and Fb to have the lowest possible power control on max power with no "sound-fall" around / at lower Hz than the Fb at +3dB=60Hz/rise=12dB cabin gain + acceptable vent air velocity and group delay - compared to a closed and a 6th order bandpass box. All of these 3 the vented is the loudest at 30ish Hz up to 58 - 60 Hz, so this on 3D. Other types of boxes I did not simulate, because always at least in 1 aspect is not matching my needs.
