The Process

What We Do

Everything we build starts with a client specification and ends with a signed-off cabinet ready for dispatch. What happens in between is a five-stage process refined over thirty-five years to deliver precision, consistency, and quality that the world's leading audio brands depend on.

This page sets out how we work. Not to impress with jargon, but to show that every step has a reason, every material choice has a purpose, and every tolerance exists because the end product demands it.

Stage 01

Material Selection and Programming

Every cabinet starts long before anything is cut. Baltic Birch is sourced for its density, consistency, and acoustic integrity. Each sheet is inspected, graded, and matched to the project specification. Alongside the material preparation, the CNC programmes are written bespoke for each cabinet design, translating engineering drawings into machine-ready toolpaths. By the time the first cut is made, every dimension, every joint, and every tolerance has already been decided.

Baltic Birch is not a compromise. It is a deliberate choice made for its uniform core structure, minimal void content, and predictable acoustic behaviour. Commodity plywood varies from sheet to sheet. Baltic Birch does not. When a client specifies a cabinet to perform within defined acoustic parameters, the material has to be as consistent as the machining. That starts with sourcing and inspection before a single sheet enters the workshop.

Machining and Shaping

The CNC routers execute what the programming stage defined. Baltic Birch is cut, routed, and shaped to tolerances measured in fractions of a millimetre. The precision at this stage determines everything that follows. A cabinet that is even marginally out of specification at machining will never recover that accuracy downstream. This is where thirty-five years of process refinement shows.

Every toolpath is verified against the original engineering drawing before the first production run. Test cuts confirm dimensions, edge quality, and fit. The CNC machines are maintained to a schedule that prioritises accuracy over uptime, because a machine running fast and drifting by half a millimetre is worse than a machine running steady and holding tolerance.

Hand-Built Assembly

Machined panels become cabinets. Joints are glued, clamped, and set by hand, combining the accuracy of CNC machining with the judgement of experienced craftspeople. Internal bracing, driver mounting points, and port geometry are all assembled to the original specification. Every cabinet is checked against the engineering drawing before it moves forward.

There is a reason this stage is not automated. Assembly is where the judgement of an experienced craftsperson catches what a machine cannot: a panel that needs fractionally more pressure in the clamp, a joint that seats better from a different angle, a brace that needs a final check before the adhesive sets. Our assembly team has decades of combined experience, and that experience shows in every cabinet that leaves the bench.

Spray Shop

Coatings are selected to match the client's specification, from hard-wearing textured finishes for touring cabinets to high-gloss lacquers for installation work. The choice of primers, sealants, and topcoats is as considered as the choice of timber. Each cabinet receives multiple coats, with sanding between passes, in a controlled spray environment.

The spray shop is not a cosmetic afterthought. The coating system affects acoustic damping, moisture resistance, durability under transport, and long-term appearance. A touring cabinet that will see the inside of a hundred flight cases needs a different finish from an installation cabinet that will sit in a fixed position for a decade. We specify the coating system to match the application, not the other way around.

Inspection of cabinet specifications against engineering drawings.
Stage 05

Final Inspection and Dispatch

Every cabinet is inspected against the original specification before it leaves the workshop. Dimensions, finish quality, hardware fitment, and cosmetic standards are all checked. Cabinets are packed to survive freight and dispatched from Calne. Nothing leaves the workshop without sign-off.

Final inspection is not a formality. It is the last opportunity to catch anything that does not meet the standard, and it is taken seriously. Every cabinet is measured, visually inspected under controlled lighting, and assessed for fit and finish against the client's specification document.

Built to Last

Materials and Standards

Baltic Birch

Baltic Birch plywood is sourced specifically for its uniform core structure, minimal void content, and predictable acoustic properties. Unlike commodity plywood, which varies in density and consistency from sheet to sheet, Baltic Birch provides the stable, repeatable base that precision speaker cabinets demand. Every sheet is inspected on arrival and graded before it enters the production workflow.
