auna speaker Covers: make your sound safe
Have you just purchased a pair of Numan speakers and are wondering how best to protect them, not only against dust but above all, to prevent the cones from being accidentally damaged by children, pets or accidental contact?
Carefully check the exact model of your speakers, and visit our product gallery to purchase the corresponding speaker covers conveniently online, without any shipping costs. This way, you can protect your investment, ensure maximum durability, and further enhance the look of your speakers. Our speaker covers are made from a special vintage speaker grill cloth, specifically designed to protect without altering sound propagation so that you can enjoy the best possible acoustic and visual experience.
Types of speaker grill covers
A loudspeaker cover (or speaker grill) is usually found in front of many types of loudspeakers, both consumer and professional, and consists of a hard or soft panel mounted directly over the front part of the loudspeaker. Its main function is to protect the driver element and the interior of the loudspeaker (and possibly other audio components) from contact with external objects without compromising the proper passage of sound. As it’s placed just on the driver, the speaker cover interacts somehow with the sound produced. For this reason, it is important at the design stage to find an appropriate compromise between protection and acoustic properties, also depending on the use of the loudspeaker.
Soft speaker grills
Soft speaker grilles can be made from any fabric, weave, stitching, foam, fabric padding and other similar materials. In general, soft grilles impose little resistance on the loudspeaker because the material is free to move in sync with the sound waves. Because the grille can absorb this vibration, softer grilles are less likely to produce noise, except at extremely high sound pressure levels..
Also, they offer protection from small, lightweight objects and can be water-resistant to a point, but they are likely to be torn or even stretched enough to reach the speaker.
Rigid speaker covers
Rigid grilles are normally made from materials such as metal, wood or plastic. Some solid grilles are also made from a board or sheet of material with holes or cuts to allow sound to pass through, while others are made from thin strips of material either crisscrossed together or evenly spaced in parallel.
Because hard material is not as free to move with the speaker’s sound as soft material, the output level of the drivers must be carefully considered when designing the speaker grille. A grille with more holes will allow the sound to pass through but will offer less protection from small objects. Too much material in front of the driver will begin to distort at higher sound pressure levels, and in severe cases, could damage the driver, resulting in unwanted rattling.
When not to use a speaker cover
Some loudspeakers have such specific characteristics that a grille would interact too much with the sound to be practical. Studio monitors, for example, must reproduce audio so accurately and linearly that anything placed in front of the speaker could obscure aspects of the sound. For this reason, they usually don’t have grilles.
On the other hand, high-power subwoofers, such as those used in high-end car audio applications, produce such violent sound waves that a grille could easily rattle or be damaged while the driver is under load. All but the sparsest grilles also can diminish or distort the low-frequency waves produced.
Some loudspeakers simply do not need a grille, perhaps because they are enclosed in a case, such as the speakers found inside personal computers, and are not intended to produce high-fidelity audio, only audible tones and noises.
