A sealed three-way tower with a shaped baffle, continuous vertical bevels and a floating plinth. JP1 brings the MP1 driver direction into a more restrained architectural form.

JP1 / Finish studies
Quiet graphite. Deep piano black. Bright racing red lacquer. Porcelain white. Explore the character of JP1 in four considered finishes.
Finish concept
Understated satin. Sculpted by light.
AI-assisted design visualisations. Cabinet and component details are illustrative; the engineering record defines the build.
Explore JP1 / Interactive studio
Rotate the selected cabinet, explore five finishes and move closer to the flowing bevel and floating base.
The interactive studio opens separately so you can explore the model in full screen.
Design 8 cabinet visualisation. Driver models and finishes are illustrative; this is not a manufacturing drawing or an acoustic simulation.
01 / In the workshop
Music: Gymnopédie No. 1 by Erik Satie, performed by Kevin MacLeod · CC BY 3.0. Excerpt, level and fades edited for this film.
02 / The selected design
JP1 follows the rectangular Quiet Tower direction: a three-way layout, bevelled vertical edges and a shaped transition between the upper drivers and bass section.
Design 8 is the selected version. The reference records a 36 mm front and bevels labelled 72 × 30. It guides the appearance; the final construction dimensions belong to the engineering drawings.
03 / The development record
Dated entries connect the design decisions to the work on the bench. New chapters will be added as the build progresses.
Three original camera recordings document the panel machining. The film brings the sequence together and revisits the right-hand corner at half the source playback speed, with an overview inset to keep the detail in context.
The close view records the edge as the extraction shoe passes. Dimensional verification is a separate operation.
The 36 mm front-panel version is the chosen visual direction for JP1. The project will use the MP1 driver family, with the final installed components and tuning recorded as the build develops.
04 / Still to come
Dry assembly, joint alignment, glue-up and clamping. Photographs of the inside before it is closed.
Preparation, edge details and the chosen finish, documented through to the completed cabinet.
Drivers, wiring, damping and the active system. Record each meaningful tuning revision.
Measured results with their test conditions, followed by clearly identified listening observations.
05 / Evidence, as it arrives
JP1 is in development. Final response, output, distortion and crossover figures are not published here yet. Measurements will be tied to the actual cabinet and settings used.
Build recordMaterials, component identities, cabinet revision and the changes made along the way.
Test recordMicrophone position, measurement conditions, calibration and system settings alongside the results.
The selected direction shares the MP1 driver set: BlieSMa tweeter, Purifi midrange and FaitalPRO bass driver. Exact installed model references will be confirmed in the build record before the final specification is published.
The hero renders and finish studies are AI-assisted design visualisations based on cabinet and driver references. They are not photographs or exact engineering models. The machining footage and its extracted stills record the real build. The film's illuminated XOP Acoustics workshop opening is an AI visualisation. The cabinet comparison is a design reference. Neither is presented as a photograph of the finished speaker.
