An acoustic panel includes a first skin, a second skin and a cellular core vertically between and connected to the first skin and the second skin. The cellular core includes a plurality of cavities, a plurality of sidewalls and a plurality of septums. Each of the plurality of cavities extends vertically through the cellular core between the first skin and the second skin. Each of the plurality of cavities extends laterally within the cellular core between a respective laterally adjacent pair of the plurality of sidewalls. Each of the plurality of septums vertically divides a respective one of the plurality of cavities into a set of fluidly coupled sub-cavities. A set of the plurality of septums is formed by a ply of folded material. Each of the set of the plurality of septums have a four-sided polygonal shape when viewed in a plane that is parallel to the first skin.
