A skeletal mounting chassis designed to hold a custom 50mm driver assembly. The aggressive cutouts strip away unnecessary mass, leaving four sweeping struts that provide rigid support while entirely opening the rear wave to prevent acoustic reflections. The base houses a precision-cut cavity tailored to scavenged PC fan magnets, complete with a vented central pole piece. Acoustic Details Rear Ventilation: 50-degree windows cut low into the voice coil gap ensure maximum airflow and heat dissipation. Magnet Housing: A 28.5mm OD x 5mm bottom slot sized specifically for standard 120mm fan ring magnets. Mounting Interface: 50mm outer diameter upper ring with a 2mm wall thickness for standard cone attachment.
