I'm designing a portable speaker with two Alpine S-S40 and a Lanzar Maxp64 subwoofer. The plan is to make it as compact as possible but giving each component its own sealed box. My question is if the shapes of the individual boxes are fine and won't impact negatively on the sound of each driver. If I make the Alpines boxes rectangular, the Subwoofer box would have a T shape. I'm heading to 1L for the woofers and 20L for the subwoofer, in the design shown, they have 1,9L and 17,5L respectively.

I'm installing RP2040 Picofly on this Switch Lite, at first the chip didn't turn any light, the screen was black and it did that hissing noise. I tried retouching the solderings that looked bad, and now it turns on, until it stops and starts doing the noise again. What should I check?
