*Poly-fill 80% of the volume in order to achieve a flatter frequency response. (less boomy).
*Box dimensions are external using a 3/4” baffle.
*Approximate adjusting point for the subsonic filter, it should be adjusted until it is audible.
*For less air turbulence, round off inside and outside port edges and fill in the corner to avoid
sharp angles.
*Placing the port in the center of the box will further brace the enclosure.
*circular ports are calculated to fit the same enclosure as slotted port.
