Title: JBL's Differential Drive Transducers
https://jblpro.com/en-US/site_elements/tech-note-jbl-s-differential-drive-transducers
Differential Drive technology in detail. 2. Anatomy of a Differential Drive transducer: The simplest way to understand Differential Drive is to compare it directly with JBL’s traditional motor structures. Figure 1 shows a section view of a tradi-tional JBL magnet-voice coil assembly and a Differential Drive system. As a starting point, let us

A true differential input provides a higher sound quality than a differential signal going into one amplifier. The true differential amplifier requires an additional circuit to produce the differential input from a single-ended signal. The easiest implementation for the audio amplifier is the signal into one amplifier (Fig. 3). In single-ended ...
ADC Drivers | Analog Devices

Differential signaling is the undisputed champion for conveying analog signals, audio or otherwise, across distances with minimal noise pickup. One of the big concerns during the design of differential drivers is the capacitance at their output. This capacitance comes from actual capacitors added to the line as well as the parasitic capacitance ...

Starting from scratch and often developing patents in the process, JBL engineers always develop from the ground up, resulting in technologies, such as Differential Drive woofers, CMCD Cone Midrange drivers, and the D2 Dual Voice Coil Compression Driver, that cover the entire practical bandwidth of professional audio devices.
Design of High-Performance Balanced Audio Interfaces
https://www.jhbrandt.net/wp-content/uploads/2014/11/Design_of_High-Performance_Balanced_Audio_Interfaces.pdf
Since there is no difference in the two noise voltages, the differential amplifier has no output and the noise is said to be rejected. Since the audio signal from Device A generates a voltage difference between the Device B inputs, it appears at the output of the differential amplifier. Therefore, we can completely rejects the ground noise if the
