D Routing Index
This page is a routing index for D-terms. It is meant to help readers move quickly between digital-audio vocabulary, speaker-behavior terms, and installation language that often overlap in real troubleshooting and tuning work.
The D section is especially useful when a problem sits on the border between physical install quality and signal-chain setup, which is why so many entries point into both measurement and DSP chapters.
Digital Audio and Signal Chain
- DAC (Digital-to-Analog Converter): Chapter 5.2 and Chapter 12.1.
- Dirac Live: Chapter 12.6 and Chapter 12.7.
- DIN size and Double-DIN: Chapter 5.1.
- Dynamic range: Chapter 5.2 and Chapter 13.2.
- Delay, time: see time-alignment material; delay, group appears in Chapter 9.1 and Chapter 10.2.
DSP and Measurement Workflow
- DSP (Digital Signal Processor): platform selection, configuration workflow, FIR vs IIR filters, and setup examples in Chapter 12.
- dB (decibel): reference levels, SPL scale, and multi-source addition in Chapter 6.2 and Appendix A.
- Decay time: waterfall-plot interpretation in Chapter 9.1.
- Distortion: amplifier THD, measurement practice, and speaker nonlinearity in Chapters 4, 6, and 10.
- Directivity: Chapter 1.4.
Installation and Hardware Terms
- Damping factor: Chapter 6.1.
- Dash kit: Chapter 2.6.
- DC resistance: Chapter 7.4 and Chapter 10.7.
- Dielectric grease: Chapter 2.2 and Chapter 11.3.
- Distribution block: Chapter 2.2, Chapter 3.2, and Chapter 11.5.
- Door installation: Chapter 2.4 and Chapter 3.1.
- Dust cap: Chapter 9.3.
- DVC wiring and Dual voice coil: Chapter 2.2 and Chapter 9.2.
Cross References and Brands
- Deadening, sound: see sound-deadening content.
- Diaphragm: see cone-related speaker terminology.
- Dolby Atmos: Chapter 14.1.

Where To Go Next
If your D-term is really a tuning or calibration question, continue into Tuning or DSP. If it is a physical-install question such as distribution blocks, dash kits, or DVC wiring, continue into Installation or Electrical.
