When you get into subwoofers with a lot of power, xmax, and strong motor force, acoustical energy becomes a very real factor. The enclosure has to be able to handle that energy without excessive flex or resonance. When enclosure panels flex, it puts additional stress on joints and hurts overall performance, leading to output loss and reduced efficiency.
This build is a simple but properly engineered ported enclosure for 2 15” Kicker SoloX 15 subs. The client didn’t want the added weight that comes with 1” Baltic/MDf or double laminated walls, so instead I focused heavily on internal bracing to keep the enclosure rigid and controlled.
We all know kickers love their air volume, 10.25 ft3 tuned to 34hz. Clean, strong, and built to stay musical while handling serious power, allowing for an enclosure capable of doing 150db+ with ease.
