Behind the Scenes at the Sunship Audio Workshop
A day at Sunship Audio begins with listening rather than machinery. In a Berlin workshop where custom horn-loaded loudspeakers are designed and built, every decision is connected to the final musical experience. Cabinet proportions, horn geometry, driver selection, and crossover behavior all have to work together as one coherent system.
The work combines traditional cabinetmaking with precise acoustic engineering. Heavily braced birch plywood enclosures provide a rigid foundation, while bi-radial wooden horns control dispersion and give the compression drivers a carefully shaped acoustic environment. The result is large-format loudspeaker design pursued with the patience of a specialist craft.
This is also a highly personal process. Systems are produced to order, and the listening room provides a practical reference throughout the day. Before a pair leaves the workshop, it must satisfy measurements, construction standards, and the more demanding test of sounding natural with real music.
Morning Starts With Listening
The first part of the day often involves reviewing work from the previous session. A cabinet may be checked for joinery, a horn surface inspected under changing light, or a crossover compared against its intended specification. Small details matter because a custom loudspeaker is assembled from many parts that must remain mechanically and acoustically consistent.
Listening is used as a form of quality control, not as a substitute for measurement. Familiar recordings can reveal whether the tonal balance remains even, whether vocals occupy the correct physical space, and whether bass arrives with the timing expected from the design. A short session can expose an issue that is difficult to see on a workbench.
The Berlin demonstration room becomes especially useful at this stage. It allows the team to move between close inspection and full-system playback, examining how the loudspeaker behaves in a real listening environment rather than judging isolated components alone.
Building A Cabinet That Stays Quiet
Birch plywood is selected for its strength, stability, and useful working properties. In a high-sensitivity horn system, the enclosure should contribute as little unwanted sound as possible. Panels are therefore cut accurately, joined securely, and supported with substantial internal bracing to reduce vibration and flexing.
Cabinet construction is a measured sequence rather than a rushed assembly. Dry fitting confirms alignment before adhesive is applied, while internal parts must leave sufficient space for drivers, crossover components, wiring, and service access. A small error at this point can affect later stages, especially when the horn and woofer need to sit in precise acoustic relationship.
Finishing work follows the structural stages. Edges are refined, surfaces are prepared, and the visible character of the wood is considered alongside durability. The cabinet must look purposeful, but appearance remains tied to function: smooth transitions, accurate openings, and solid mounting surfaces all support the performance goal.
Shaping The Acoustic Front End
The horn is one of the most recognizable elements of a Sunship Audio system. A bi-radial wooden horn controls sound in two dimensions, helping the compression driver couple to the room with a defined pattern of dispersion. Its shape is therefore an acoustic component, not decorative furniture added around the driver.
Crafting such a part demands careful attention to curvature and surface continuity. The throat, flare, mounting interface, and mouth must work as a single geometry. Any irregularity can create unwanted reflections or alter the way energy spreads through the listening space, which is why finishing and inspection take considerable time.
| Workshop Stage | Main Focus | Desired Result |
|---|---|---|
| Cabinet preparation | Panel accuracy and internal bracing | A rigid, low-resonance enclosure |
| Horn construction | Bi-radial geometry and smooth surfaces | Controlled dispersion and clean wavefront behavior |
| Driver installation | Secure mounting and correct spacing | Stable mechanical and acoustic alignment |
| Crossover assembly | Component matching and wiring discipline | Consistent integration between drivers |
| Listening verification | Musical balance and room interaction | A natural, convincing presentation |
Once the horn is ready, the compression driver can be mounted and checked for a secure fit. The broad wooden surface also becomes an important visual signature, connecting the technical purpose of the design with the handcrafted identity of the finished loudspeaker.
Matching Drivers And Crossovers
Sunship Audio systems are based around TAD-Pioneer compression drivers and woofers, selected for their ability to deliver high efficiency, dynamic range, and detailed transient response. The driver pair is treated as a system: the woofer must integrate smoothly with the horn, and both sections must remain balanced across the intended operating range.
The passive crossover is central to that integration. Its components are mounted and wired with attention to layout, reliability, and repeatability. A time-aligned approach aims to bring the acoustic output from the different drivers into a more coherent relationship at the listening position, preserving the timing cues that help music feel focused and immediate.
This stage may involve both inspection and revision. Measurements can indicate where a response needs refinement, while listening reveals qualities such as vocal presence, rhythmic definition, and the texture of instruments. The goal is not an exaggerated effect, but an open and controlled presentation that remains engaging over long sessions.
The Final Build And Room Check
Assembly brings together the results of several disciplines. The drivers are secured, the crossover is installed, wiring is routed cleanly, and panels are checked for unwanted movement. Because the systems are custom-built, the final configuration can involve details specific to a client’s room, preferences, and chosen finish.
A complete pair is then given time in the listening room. Placement, toe-in, room boundaries, and listening height can all influence the result, particularly with a large horn system that has deliberate directivity. The workshop team can assess whether the physical design and the room are working together as intended.
Visitors can experience this process through the Sunship Audio workshop, where the company presents its loudspeakers alongside the design philosophy behind them. Hearing the system in a prepared space helps explain why cabinet rigidity, horn geometry, and crossover timing are treated as connected parts of the same project.
What A Finished System Should Reveal
The most successful result is heard in the relationship between scale and subtlety. A horn-loaded loudspeaker can produce powerful dynamics and high output with relatively little amplifier effort, yet it should also preserve low-level detail, tonal color, and the shape of a recording’s acoustic space.
Bass performance is judged by definition as much as depth. The woofer should support the room without becoming slow or detached from the horn. Voices should sound anchored rather than projected, and percussion should start and stop with convincing precision. These qualities are especially revealing on familiar recordings.
The listening session also provides a final opportunity to confirm consistency between the two loudspeakers. Stereo imaging, tonal balance, and response symmetry need to hold together across the listening area. Only after the system has met these practical and musical checks is the workshop day truly complete.
Selecting A System For Your Room
A custom loudspeaker should be considered as part of a complete playback environment. Room dimensions, listening distance, amplifier choice, music preferences, and desired output level all influence which configuration will be most appropriate. A thoughtful conversation before construction can prevent compromises later.
The best preparation is to bring familiar recordings and spend time with the demonstration system. Notice how easily voices lock into the center, whether bass remains articulate, and how the presentation changes when you move around the room. These observations are more useful than focusing on specifications in isolation.
- Measure the listening room and note speaker-placement limitations.
- Bring recordings that expose vocal tone, bass control, and spatial depth.
- Discuss amplifier compatibility and preferred listening levels.
- Ask how horn directivity may interact with nearby walls and furnishings.
- Allow time for a proper listening session before commissioning a system.
A workshop day at Sunship Audio is therefore a continuous exchange between material, measurement, and music. The finished loudspeaker carries visible evidence of skilled construction, but its real purpose emerges when the drivers, crossover, cabinet, room, and recording become one uninterrupted musical event.
