AB  - Successful application of negative damping factors to loudspeakers is not so difficult a task as one would infer from the literature of recent years. Foremost in importance are the cancellation of voice-coil inductance as well as resistance, equalization for low frequency radiation characteristics; and utilization of infinite baffle rather than a reflex or horn type. When satisfactory attention is granted these factors, substantial improvement in loudspeaker performance is almost certain. In a typical application of a negative impedance amplifier, resonant hangover is eliminated, the nonlinear distortion halved, and the low frequency response leveled and extended about an octave.
