I compared LoudspeakerLab simulations of five DIY speakers with published Klippel measurements, using both in-cabinet measurements and manufacturer driver data.
The study compares Mechano23, Parts Express Copperhead, Overnight Sensations MT, Samba MT, and C-Note against completed-speaker Klippel-style references.
It compares LoudspeakerLab simulations built from mounted in-cabinet measurements with simulations built from ordinary manufacturer or spec-sheet driver curves.
Models from mounted-driver measurements are generally close to the difference expected between two careful DIY builds, while spec-sheet models usually differ more.
