I want to build a spherical speaker with a diameter of about 50 cm. The frequency response should be relatively deep. Now my question is, which type of plastic is best for it and how thick does the housing have to be?
The most durable plastic for a loudspeaker enclosure is polypropylene. It is strong, impact-resistant, and can withstand high temperatures without warping or deforming.
Acrylonitrile Butadiene Styrene (ABS) is known for its excellent sound-dampening properties, making it a popular choice for loudspeaker enclosures. It also has a smooth surface that helps reduce unwanted vibrations and distortions.
While it is possible to use recycled plastic for a loudspeaker enclosure, it may not provide the same level of durability and sound quality as new plastic. The quality of the recycled plastic can vary, so it is best to use new plastic for optimal performance.
Yes, there are several environmentally-friendly options for loudspeaker enclosures, such as bioplastics made from renewable resources like corn starch or sugarcane. These plastics are biodegradable and have a lower carbon footprint compared to traditional plastics.
It is important to choose a plastic that is suitable for the specific requirements of a loudspeaker enclosure. Some plastics may not have the necessary strength or sound-dampening properties, which can affect the performance of the loudspeaker. It is best to consult with a professional to determine the most suitable plastic for your specific needs.
