This paper studies the acoustic properties of a tree orchestra consisting of four wood-panel loudspeakers and proposes an equalizer (EQ) design for each loudspeaker. Two design strategies for graphic equalization on Bark
bands are considered: a single- and a multi-point approach. Asymmetries in the wood-panel speakers cause their magnitude responses to vary so much in different directions that the multi-point averaged EQ gets smoothed and does
not have much effect. A single-point EQ, designed based on the frontal response, changes the magnitude response more and improves the overall shape of the response substantially in front of the panels. The magnitude responses at other measurement points are also improved. The EQ
does not attenuate the ringing of the wood-panel modes much, thus retaining their resonant quality. The orchestra of equalized wood-panel speakers is used in a science center to showcase acoustic properties of wood.
