# LoudspeakerLab

> LoudspeakerLab is a free web application for designing DIY loudspeakers. It hosts a
> public database of measured loudspeaker drivers with Thiele-Small parameters, a box
> and baffle simulator, and an automatic passive crossover optimizer that reports
> CTA-2034A spinorama predictions.

All content linked below is public and readable without an account. Driver pages carry
an evidence grade describing measurement provenance, so a citation can state how the
underlying data was obtained.

## Core pages
- [Home](https://loudspeakerlab.io/): what the platform does and how a design is built.
- [Driver database](https://loudspeakerlab.io/drivers): every published driver with T/S parameters, frequency response, impedance, and evidence grade.
- [Public designs](https://loudspeakerlab.io/designs): completed speaker designs with simulated response, impedance, and full component lists.
- [Simulation accuracy](https://loudspeakerlab.io/accuracy): five DIY speakers compared against published Klippel NFS measurements, with the method and the residuals.
- [FAQ](https://loudspeakerlab.io/faq): how measurements, evidence grades, the solver objective, preference rating, and enclosure modelling work.
- [Measurement guide](https://loudspeakerlab.io/measurements): how to capture and upload gated far-field FRD/ZMA data.
