Hand-Built Assembly

Machined panels arrive at the assembly bench as individual components: precisely cut, dimensionally verified, and ready to become a cabinet. What happens next is the part of the process that no machine can fully replicate, and it is the part that most clearly shows the difference between a manufacturer that builds cabinets and a workshop that crafts them.

Assembly at Sarivale is done by hand. Not because we lack the technology to automate it, but because speaker cabinet assembly requires a level of judgement that automation cannot provide. Every joint has a character. Every panel interaction has a feel. An experienced assembler knows when a clamp needs fractionally more pressure, when a joint is seating perfectly, and when something is not quite right, often before a measurement confirms it. That kind of knowledge does not live in a programme. It lives in the hands of people who have been doing this work for years.

The adhesives used in assembly are selected for the specific application. A touring cabinet that will spend its life being loaded in and out of flight cases needs an adhesive system that can absorb vibration and impact without failing. An installation cabinet that will sit in a fixed position for a decade needs long-term structural stability. The adhesive is not an afterthought, it is an engineering decision that affects the cabinet’s performance for the whole of its working life.

Internal bracing is positioned according to the engineering specification and bonded during assembly. The placement of every brace affects the cabinet’s resonant behaviour, its structural rigidity, and its weight. Moving a brace by even a small amount can change the acoustic properties of the enclosure. Our assemblers work from the engineering drawing, not from habit, and every brace position is checked before the adhesive sets.

Driver mounting points are prepared during assembly to ensure that the speaker drivers, when fitted by the client, sit exactly where the acoustic design intended. Mounting holes are positioned, threaded inserts are fitted where specified, and the mounting face is checked for flatness. A driver that does not mount flush to the baffle creates an air leak that degrades acoustic performance. We eliminate that risk at the assembly stage.

Port geometry, where the cabinet design includes ports, is assembled to the specified dimensions. Port length and cross-sectional area directly affect the cabinet’s tuning frequency. A port that is even slightly out of specification changes the acoustic response. Our assemblers understand this relationship, which is why ports are measured and verified during assembly rather than assumed to be correct because the panels were cut accurately.

Every assembled cabinet is checked against the engineering drawing before it moves to the spray shop. Dimensions, bracing positions, panel alignment, and joint integrity are all verified. A cabinet that passes this check has earned the right to move forward. One that does not goes back to the bench.
