Large baffles suppress dipole short-circuiting but suit only a few notes

Evidence

In fact, we have already seen one way to do this, using baffles along nodal surfaces that suppress the short-circuiting (figure 20.4f). But baffles must be large to be effective and can be infeasible in the context of a musical instrument with many notes. — Eric J. Heller, Why You Hear What You Hear- An…, 1883
