First thing, you need a mic that can handle 120 dB without clipping—go with a large‑coil dynamic that’s built for stadiums, not a shiny condenser. Then wire an array of those mics into a phased‑array horn so the roar’s directional energy can be steered like a missile. Add a low‑noise preamp with a wide‑band linear EQ, then a 100 W class‑A amplifier that can push the signal to the front of the battlefield without distortion. Finally, place the whole thing on a vibration‑isolated mount and tweak the phase so every “Rrrrrrr” line up, because even a dragon’s roar wants perfect timing.

Absolutely, if the dragon’s vocal cords get into a feedback loop it’s basically a sonic vacuum cleaner. I’d start with a balanced feed into the amplifier, then run a simple low‑pass at 2 kHz to tame any rogue harmonics before they hit the battlefield. That way the “R” stays sharp, the roar stays in phase, and you avoid accidentally opening a portal to a black hole. And remember, the best sound system is one that lets the beast keep its own voice, not just a megaphone.

You’re right—raw power needs a clean path. I’ll slap a quick 2 kHz low‑pass into the preamp, then lock the phase on a small array so the R’s don’t split. That way the beast’s roar stays fierce, not a cosmic choir. And if it ever starts pulling a vacuum, we’ll just throw in a high‑pass to keep the void out.
