Before the small paragraph about me, the owner of this website and the Instagram page @plans.systemes I want to thanks some persons who helped me through my journey, and without who, most of the content I made since the 7 August 2021 would simply have never existed.

Pao is passionate about drawing and art in general, she’s been here from the start, encouraged me creating my Instagram page, drew my new logo and helped filling the encyclopedia. I can’t thank her enough for everything.

Renaud is a carpenter and woodworker engaged in sound system building with over 20 years of experience and has been helping me from the start, completing my knowledge about the incredible sound system culture and answering some of my most technical questions.

Alex (I-Ruff sound system) has been following me since the beginning and first ordered me some private plans. Over the months he has given me feedback on my work and allowed me to improve its quality. He also have voluntarily helped filling the encyclopedia, when the website was under construction. A big thanks to him !

Florian has voluntarily helped filling the encyclopedia in order to make this website project possible. Thanks a lot.
