Commercial Devices
These are speaker grilles found in headphones and other consumer devices, such as home audio systems. Commercial device speaker grilles must focus on cosmetics. Quality is critical, and each perforation needs to be perfect. Grilles for these applications are usually painted.
Automotive Speakers
Like commercial devices, these grilles are heavily cosmetic. The grilles must be designed to both protect the speaker and be aesthetically pleasing.
Industrial Applications
Speakers for industrial applications are often heavy-duty and do not always require particular aesthetic considerations. These speakers are often mounted in the ceiling of office complexes or sit on top of an amplifier on stage during a concert.
