The Contrabass Series products capture the bold and dynamic characteristics of the contrabass. Choose between a Reflex, Multiload, or a bandpass; the Contrabass Series has it all. The aim is to deliver deep, impactful bass that defines the lower frequency extension of the audio spectrum, making them ideal for both live sound and installation applications. Engineered to ensure minimum cabinet resonance, they disappear in a venue and are in different shapes and sizes that fit under a stairway, stand next to a column, or simply can be slipped under a stage without losing the high-impact performance. These subwoofers enhance low-frequency extension and overall audio presence, making them perfect for high-energy environments. These are ideally paired with the Cello and String Series mid-highs. Choose from our range of Contrabass and String series subwoofers to play, hear, and feel the music.
