Sub-Bass and City Walls: Sound Systems of the Underground

The engineers who build speaker stacks from scrap and faith — and the physics of making a wall move.

By Theo Adeyemi 2025-09-23

Ask any sound engineer how their system came together and you will get a different answer: a PA from a closed cinema, amplifiers salvaged from a church, cables that have outlived three governments.

The underground sound system is an act of collective engineering. The bass is not heard so much as inhabited — it moves through the floor, the walls, the chest, until the room itself becomes an instrument.

A good system doesn't play music. It rents out the room for the music to live in.

We visited the builders, measured their rigs, and stood in front of the stacks long enough to understand why the ears ring but the heart doesn't mind.
