+## 🛡️ Dual-Driver Virtual Thermal Guards & Power Caps
+
+Because Linux cannot access the T2 hardware current-sensing ADCs, we implement a **Virtual Voice-Coil Thermal Model** that models continuous electrical power dissipation ($P = V_{\text{rms}}^2 / R_{\text{vc}}$) and exponential cooling into the air gap:
+
+$$C_{\text{th}} \frac{d\Delta T(t)}{dt} = \frac{V_{\text{rms}}^2(t)}{R_{\text{vc}}} - \frac{\Delta T(t)}{R_{\text{th}}}$$
+
+### Thermal Guard Configurations
+
+* **Woofer Thermal Guard (`thermal_guard` @ Post-`wlim`):**
+  * **Continuous Power Cap:** **$1.0\text{ W}$ ($1,000\text{ mW}$)** per channel ($16\%$ of max $6.25\text{ W}$ peak power).
+  * **Linear RMS Threshold (`al`):** `0.4000` ($-7.96\text{ dBFS}$ RMS).
+  * **Heating Tau ($\tau_{\text{heat}}$):** $2,500\text{ ms}$ (2.5 seconds).
+  * **Cooling Tau ($\tau_{\text{cool}}$):** $5,000\text{ ms}$ (5.0 seconds).
+* **Tweeter Thermal Guard (`tweeter_thermal_guard` @ Pre-`tlim`):**
+  * **Continuous Power Cap:** **$100\text{ mW}$ ($0.100\text{ W}$)** per channel ($1.6\%$ of max $6.25\text{ W}$ peak power).
+  * **Linear RMS Threshold (`al`):** `0.126491` ($-17.96\text{ dBFS}$ RMS).
+  * **Heating Tau ($\tau_{\text{heat}}$):** $1,000\text{ ms}$ (1.0 second).
+  * **Cooling Tau ($\tau_{\text{cool}}$):** $2,000\text{ ms}$ (2.0 seconds, fast decay recovery from Zoom/WebRTC glitches).
+
+> **Acoustic Result:** Dynamic music (Blues, Classical, Rock) has high crest factor ($12\text{ dB} - 18\text{ dB}$) and operates at $0\text{ dB}$ gain reduction with full peak dynamics. Continuous high-power signals (full-volume white noise or sine sweeps) are automatically attenuated to harmless power levels after ~2 seconds.

+## ⚠️ AT-YOUR-OWN-RISK DISCLAIMER & Replacement Resources
+
+> [!CAUTION]
+> **USE AT YOUR OWN RISK:** Loud signals in general, as well as all continuous loud audio (e.g. uncompressed music, white/pink noise, full-volume sine sweeps, or software glitches), carry an inherent physical risk of voice-coil overheating, mechanical over-excursion, or permanent speaker driver damage.
+>
+> While this DSP engine includes virtual thermal-emulation limiters and dynamic excursion limiters as a **best-effort protective measure**, this software is provided **"AS IS", WITH NO IMPLIED WARRANTY OR GUARANTEE OF ANY KIND**. You are solely responsible for protecting your own hardware and managing playback volume levels. The authors and maintainers assume no responsibility or liability for damaged speaker cones, blown voice coils, or hardware failures.
+
+### 🔧 Speaker Replacement & Repair Resources for Power Users
+For expert users who wish to customize thresholds, push thermal limits higher will run a risk of speaker blowout.
+Dont increase the limits unless you understand and are prepared for a speaker-driver replacement process at your own risk.
+If you wish to replace speaker drivers or to be able to do so yourself  these instructions and part-links may help.

+* 🛒 **Replacement Speaker Modules:** Cheap OEM speaker assemblies are readily available if you ever push limits and need a fresh set of drivers: search for MacBook Pro 15,1 / 15,2 (A1990 2018/2019) Left & Right Speaker Assemblies on [iFixit Parts](https://www.ifixit.com/Parts/MacBook_Pro_15%22_Touch_Bar) or [eBay A1990 Speakers](https://www.ebay.com/sch/i.html?_nkw=macbook+pro+a1990+speakers).
