DIY Custom Speakers, Components and Accessories
DIY speakers give you control over exactly what you build — the driver complement, the enclosure, the crossover and the voicing — instead of settling for an off-the-shelf box that’s close enough. Surgesound supplies the same professional transducers and components that go into commercial touring and install systems, so a DIY build can perform to a genuine professional standard rather than a hobbyist one.
This page brings our component range together for the DIY speakers market in one place: drivers, horns, crossovers, amplification, cabling and the design, measurement and tuning support to tie it all together. Whether you’re building a single subwoofer, a full active three-way, or a run of matched cabinets, you can source every part from one supplier and lean on our technical team where you need to.
Transducers, LF Drivers, Compression Drivers, Horns and Crossovers
The core of any DIY speaker is the transducers, and this is where component choice matters most. We stock professional LF drivers from brands such as B&C Speakers and 18 Sound — from long-excursion subwoofer drivers through to midbass and full-range cones — alongside compression drivers for high-frequency duty in ferrite and neodymium versions. Match those to a suitable horn or waveguide and a passive crossover network, and you have a complete passive build.
Selecting components on the right parameters is what separates a good build from a guess: power handling, sensitivity, resonant frequency, voice-coil diameter, impedance and magnet type all feed into how the drivers behave in your chosen enclosure. If you’re unsure which LF driver and compression driver will work together, the Surgesound team can help you specify a combination that’s actually matched.
Amplifiers
Passive DIY builds need amplification matched to the load. Our rack amplifier range, including RAM Audio and Work Pro, covers two- and four-channel models across a wide power band, with low-impedance and constant-voltage (70V/100V) options and DSP on selected models. The key is matching amplifier power and channel count to your cabinets — drive them properly and within their limits, and a DIY system holds up under real use. We can recommend the right amplifier for what you’ve built.
For active DIY builds, a plate amplifier mounts directly into the cabinet and powers the drivers from inside the box. These modules bring onboard amplification and DSP into the enclosure itself, which suits active subwoofers and active full-range designs where you want processing and power per cabinet without an external rack. We can advise on plate-amp and module options from RAM Audio’s PowerPack DSP range that include DSP-equipped units, to suit your build.
Accessories
A truly professional DIY cabinet requires more than just premium drivers; it needs rugged, field-tested hardware to survive the road. Our curated selection of hardware gives your custom enclosures a clean, commercial-grade finish while ensuring maximum structural integrity. From heavy-duty metal speaker handles and round recessed plastic grips to durable speaker top-hats and precision-punched steel connector plates, we supply the essential components required to finish your loudspeaker project to an international touring standard.
Cabling & Connectors
Internal wiring and external connections both affect how a finished speaker performs and how reliably it holds up. We supply professional speaker cable from Van Damme along with industry-standard Neutrik connectors — Speakon and XLR — plus terminal cups and binding posts for the cabinet itself. Get the internal hook-up wire, connectors and external cabling from one place and wire the build correctly throughout.
Custom Speaker Cabinet Designs
The enclosure determines as much of the final sound as the drivers do. We provide custom cabinet designs worked out around your chosen LF drivers — sealed, ported, bandpass or horn-loaded — with internal volume and port tuning calculated and modelled rather than estimated. You get a design built to suit the drivers you’re using and the result you’re after, with the dimensions and tuning to match.
Custom Speaker Cabinet Building
If you’d rather not cut and assemble the cabinets yourself, we can build them to a Surgesound design or to your own drawings. That covers material and bracing decisions, accurate port and baffle work, and finishing, so the box you mount your drivers into is built to the spec the design calls for. Talk to us about your project and we’ll scope the build with you.
DSP Presets
A DSP amplifier or plate amp is only as good as the processing loaded into it. For driver-and-cabinet combinations we’ve supported, we can provide DSP presets — crossover, EQ, delay and limiter settings — so the build performs as intended from the start instead of being tuned by ear from scratch. This gets an active DIY system to a known-good baseline quickly and protects the drivers while you do it.
Measurement and Tuning
The last step is verifying that the build actually does what the design intended. Using Smaart-based measurement, we can check a DIY speaker’s real-world response and set crossover points, EQ, delay and limiters to match — confirming driver integration, output and protection rather than assuming them. It’s the difference between a build that measures and voices correctly and one that only sounds right in the room you happened to test it in. Contact the Surgesound team to arrange measurement and tuning support for your project.
