The workshop

One man. One workshop.
One standard.

DLM is run by one person. Most components are machined on our own CNC machine in Baesweiler — and every chassis is wound, assembled, broken in and measured by hand. One chassis, one pair of hands, one report.

Inside the DLM workshop: hand assembly of a chassis
The journey of a chassis

Five stations.
No shortcuts.

STATION 01

CNC machining of components

Baskets, pole plates and front plates aren't bought in — they're machined on our own CNC machine. Every tolerance stays in our hands, from raw part to finished chassis.

STATION 02

Winding the voice coil

Copper wire, wound and bonded layer by layer by hand — the heart of every motor. This is where it's decided how precisely a chassis will follow the signal.

STATION 03

Joining motor and basket

Magnet, pole piece and basket are centred and joined — with jigs we built ourselves. Tolerances you can't see, but can hear.

STATION 04

Cone and break-in

The cone is fitted and the chassis is broken in for 48 hours. Only when surround and spider have settled is a chassis ready for measurement.

STATION 05

Measurement and report

Frequency response, impedance, parameters: every chassis is measured individually. The report for your unit is included with delivery.

Our conviction

Why chassis only?

Because the cabinet is a matter of taste — the transducer is not. We focus on what physically defines the sound and leave the freedom of the concept to you. Developers, DIY builders and small manufacturers around the world build their own loudspeakers on this foundation.
