Too much outcoupling kills resonance just as too little silences it

Evidence

Clearly, we have to shake the speaker membrane at least a little, or no sound is launched at all. At the other extreme, if we get greedy and adjust the lever to shake the speaker a lot, the damping the speaker induces will be large, and power will suffer. The resonance peak will be broad and not as tall—that is, less power on resonance. There must therefore be an optimum amount of shaking of the membrane, not too little and not too much—an optimum pivot point. — Eric J. Heller, Why You Hear What You Hear- An…, 1050
