• Durable and discreet speakers: FreeSpace FS2SE units are rated IP55 for dust and splash resistance and come in black with removable logos for clean aesthetic integration.
• Compact, installer-friendly amplifier: Slim housing, simple cable routing, and an IEC power inlet make wall or equipment-rack mounting easy.
