The BSG-280 W from RCS Audio-Systems is a ball protection grille for enclosure speakers, specifically designed to protect speaker installations in sports and multi-purpose halls from vandalism and damage caused by ball impacts. The grille is mounted directly on the ceiling or wall above the speaker to be protected and provides a robust, stable cover made of white sheet steel. It is intended for speakers that are not ball-impact resistant and ensures minimal loss of sound transmission. The design is neutral and aesthetically pleasing, allowing it to integrate well into architectural and interior design concepts.

Applications

The ball protection grille BSG-280 W is primarily intended for use in sports and multi-purpose halls where speakers are exposed to increased mechanical stress. It protects specifically enclosure speakers such as the BC series or models like DH-115 S, BC-215 C, BC-230 C, CSP-115/220 D, PHS-81T30 BS, SPJ-52 WHBS, and SPJ-53 WHBS. Installation is directly on the ceiling or wall, making it suitable for installations in halls with high ceilings or areas requiring enhanced protection.

Functions and Equipment in Detail

The grille is made of metal and finished in white. It is robustly and stably constructed to withstand mechanical impacts such as ball strikes. Installation is done by screwing with four screws directly onto the ceiling or wall above the speaker. Dimensions are 295 mm (width) × 230 mm (height) × 100 mm (depth), enabling a precise fit for the specified speaker models. Weight is 1.3 kg, requiring stable mounting but not imposing excessive load on the mounting surface.

Technology Explained Simply

The grille is designed to minimally affect sound transmission. The openings in the sheet steel are dimensioned to allow sound to pass through unobstructed, while simultaneously absorbing mechanical impacts such as ball strikes. The use of sheet steel ensures high mechanical strength, while the white surface provides an aesthetically pleasing appearance. The construction is simple and direct, without additional elements such as rubber seals or gaskets that could impair sound transmission.

Compatibility and Accessories

The BSG-280 W is specifically designed for enclosure speakers such as the BC series, DH-115 S, BC-215 C, BC-230 C, CSP-115/220 D, PHS-81T30 BS, SPJ-52 WHBS, and SPJ-53 WHBS. It is not intended for in-ceiling speakers from the RC-/SC series or for pressure chamber or surface-mounted speakers, which are covered by other models such as BSG-260 W or BSG-350 W. Special painting in other RAL colours is available upon request, allowing the grille to be adapted to individual colour concepts.

Installation and Mounting

Installation is done by securing with four screws directly onto the ceiling or wall above the speaker to be protected. No additional mounting structure or special fastening technique is required. The installation is simple and does not require special tools or expertise beyond knowledge of the speaker system. Positioning is directly above the speaker, with grille dimensions matched to the specified speaker models.

Operational Advantages

The BSG-280 W provides effective protection against mechanical damage, especially in environments with high ball-impact risk. Sound transmission remains largely unaffected, preserving the audio quality of the speakers. The robust metal housing ensures long service life, and the white finish blends well with most interior designs. Simple installation and compatibility with a wide range of speakers from the RCS product line simplify planning and installation of sound systems in public facilities.
