Start with Sealed Enclosure Design. Sealed builds are usually the safest first choice when space is tight.
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.
This is the part of Ohmic Audio that helps you plan the system before you cut wood or buy wire.
Use the calculators first, then come here to confirm the box type, tuning approach, wiring plan, and crossover logic you can actually build.
The section pages below keep the deeper math, alignments, and engineering detail. Start at the goal cards if you are new.
Start with Sealed Enclosure Design. Sealed builds are usually the safest first choice when space is tight.
Start with Ported Enclosure Design. Use it when you want more output and are ready to manage tuning and port geometry carefully.
Start with Wiring Infrastructure so the power path, fuse strategy, and current handling are right before the system gets loud.
Start with DSP Crossover Design if the system is already installed but the speaker handoff still sounds wrong.
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.
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.
Use this when the electrical side is the real limiter: fuse planning, current capacity, voltage drop, and power delivery basics.
Use this when the parts are already chosen but the system still needs the right frequency handoff between sub, midbass, midrange, and tweeter.
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.
