How Accurate Are LoudspeakerLab Simulations? Five Klippel Comparisons

I compared LoudspeakerLab simulations of five DIY speakers with published Klippel measurements, using both in-cabinet measurements and manufacturer driver data.

Preview

Designs compared

The study compares Mechano23, Parts Express Copperhead, Overnight Sensations MT, Samba MT, and C-Note against completed-speaker Klippel-style references.

Input measurements

It compares LoudspeakerLab simulations built from mounted in-cabinet measurements with simulations built from ordinary manufacturer or spec-sheet driver curves.

Main result

Models from mounted-driver measurements are generally close to the difference expected between two careful DIY builds, while spec-sheet models usually differ more.
