hey i've been thinking of making an helmholtz resonator made from wood and i found it expensive to buy a 7 pices of 1m X 30 cm X 5cm and not so practical to have a 43cm of the resonator depth so i made this sketch of an idea i have thinkin about i just wanna know if you guys think that i can consider this idea as a traditional helmholtz resonator? or it will not reflect the knwon equations of a slat slot resonator

Well - if the volume of the box is right, and the port length and cross-sectional area is right - it ought to work I reckon. You might want to provide those details and see if someone would be kind enough to check your math.
