Design Suite

Use this when you already know the kind of build you want and need the rules that make it work. The tools help you move fast. This suite helps you avoid bad box choices, bad wiring choices, and crossover decisions that look fine on paper but fail in the car.

Tiny version

This is the part of Ohmic Audio that helps you plan the system before you cut wood or buy wire.

Builder version

Use the calculators first, then come here to confirm the box type, tuning approach, wiring plan, and crossover logic you can actually build.

Deep version

The section pages below keep the deeper math, alignments, and engineering detail. Start at the goal cards if you are new.

Start Here By Goal
Small box

Start with Sealed Enclosure Design. Sealed builds are usually the safest first choice when space is tight.

Louder bass

Start with Ported Enclosure Design. Use it when you want more output and are ready to manage tuning and port geometry carefully.

Safer wiring

Start with Wiring Infrastructure so the power path, fuse strategy, and current handling are right before the system gets loud.

Better crossover

Start with DSP Crossover Design if the system is already installed but the speaker handoff still sounds wrong.

Choose The Right Shelf

Sealed Enclosure Design

Use this when you want tight bass, a simpler first build, or the best odds of fitting the enclosure into a real vehicle without drama.

Ported Enclosure Design

Use this when output matters most and you need a clean explanation of tuning, port area, and the tradeoffs that make vented boxes work or fail.

Wiring Infrastructure

Use this when the electrical side is the real limiter: fuse planning, current capacity, voltage drop, and power delivery basics.

DSP Crossover Design

Use this when the parts are already chosen but the system still needs the right frequency handoff between sub, midbass, midrange, and tweeter.

How To Use This Suite

Translation box

  • Alignment means the overall box-and-driver behavior, not just one measurement.
  • Tuning means the note a ported box naturally wants to help the most.
  • Crossover is the traffic system that tells each speaker what range to play.

Common mistake

People often trust the calculator result and skip the reality check. The suite pages exist to catch the part the calculator does not know: vehicle space, port fit, wiring limits, and handoff behavior.

Short checklist

  • Pick the build goal first.
  • Use the tool to get a starting point.
  • Use the matching guide to stress-test the idea.
  • Only then cut, buy, or wire.
