The room

Portraits on the walls, horns in the open.

A museum ballroom is not a club. It has wood panelling, tall windows, an ornate ceiling and portraits on the walls, and nowhere to hide a speaker stack.

That suits a Void system. The design of Void cabinets brings them to the forefront of the event, instead of in the shadows, so two clusters of white horns on stands became part of the set, either side of a long table of candles and flowers.

Indoors the system is about two-thirds more powerful than its outdoor numbers, since the room lets us compress it. And the brief for a night like this is the one we tune for: a dancefloor loud enough to lose yourself on and quiet enough to whisper across.

As on every job: early load-in, cables hidden, and one of us on the system all night.

From the booth

“I DJ'ed on Chris and Lindsay's system for the first time in July 2023 and it set the standard for every other system I've ever played on— nothing else compares to this one. I've played large parties and festivals before and I can say without hesitation: this is the best system I've ever played on, by far.
What makes it different isn't just the sound, it's the human touch behind it. Sound like that doesn't happen by accident, it's the way that Chris and Lindsay have tended, cared for it and loved into being that makes the difference.”

— Daniela F., DJ at Choreomania
