For building a spherical loudspeaker enclosure with a diameter of 50 cm, considerations include material choice and thickness to minimize resonance. Roto-molded HDPE is suggested for its practicality, while composite materials like GRP may be better for prototypes to achieve a dead sound. The design must incorporate separate internal cavities for the woofer and other drivers, potentially requiring a complex assembly of subsections. An airtight construction is essential for an infinite baffle design, and cooling for the amplifier must also be addressed. Overall, detailed design planning and consultation with fabricators are crucial for optimal results.
