Projects

3SB Audio maintains a portfolio of related projects spanning loudspeakers, electronics, DSP, network transport, control, and fabrication reference work.

Some projects are primary prototype programmes, while others are enabling subsystems or shorter-cycle testbeds used to validate methods before they are folded into larger builds.

The broader company charter is documented in Philosophy, while the technical position that informs these projects is documented separately in Architecture.

Project Timeline

The portfolio is ordered newest first so recent work is easier to find.

2026

• 3SB Controller is a fixed-topology Milan orchestration service that connects ALSA audio to designated Milan listeners via an ALSA-to-Milan bridge.
• Linux AVB/Milan documents current transport-layer development around robust Linux deployment and Milan-oriented interoperability.
• Monolith Series is the current family of floorstanding and cardioid top-and-subwoofer loudspeaker models built around a shallower, wider enclosure direction.

2025

• Roon Volume Control captures the current source-selection and operational control layer.

2024

• Cardia DSP extends the portfolio into the current DSP and conversion architecture.

2023

• Ochto 8 Amplifier establishes the multichannel amplifier platform.

2022

• Bedrock Bass Extender addresses low-frequency headroom and extension.
• Keystone Speaker explores the main stand-mount loudspeaker direction.
• Stellar Bookshelf is a compact project used to validate fabrication and integration methods.

Shared Themes

Common themes across the portfolio include active topology, explicit DSP, pro-audio design cues, AoIP transport, modular electronics, CNC-friendly cabinetry, cardioid bass behaviour, and measurement-led refinement.

Development Priorities

• Measurement-led refinement rather than purely subjective tuning.
• Modular electronics that can support multiple loudspeaker projects.
• CNC-friendly cabinetry and repeatable assembly methods.
• Publicly accessible reference material where disclosure adds technical value.
