  • Design: Jean Hiraga, Le Petit, published in L'Audiophile no. 29 (1983).
  • Hole positions: after R. Berchtold (2022).
  • This adaptation: a 22 mm OSB version of the plan (3 sheets, A3), a cut layout for one 2000 × 1000 mm sheet, and a measured tuning for the Aiyima 4" full-range driver.
  • Methods: synchronized swept-sine measurement after A. Novak et al. (JAES 2015); near-field assessment after D. B. Keele (JAES 1974).

Thank you to everyone who has built Le Petit and shared plans, drawings and listening notes — this project stands on that work.
