The 18″ bass reflex subwoofer delivers a powerful and deep bass foundation that ensures a powerful and precise low bass in every application.

The bass reflex design maximizes the efficiency of the subwoofer, resulting in clear and defined bass reproduction even at high volumes. The specially developed system crossover ensures that the top unit is supplied with exactly the right frequencies to enable seamless integration between the subwoofer and satellite speakers.

The “Satellite Out” connection allows the transfer of frequencies to be perfectly matched to the connected top unit, resulting in a balanced and coherent overall system.

This makes the subwoofer particularly suitable for demanding audio applications where precise and harmonious sound reproduction is required across the entire frequency spectrum. Whether in large function rooms or at live events, this subwoofer offers the necessary power to fill the room with a full, deep bass.
