XCELSUS XAS12 Ultra Series Subwoofers

The XAS12 – ALTUM Series 12″ Subwoofer from Xcelsus is expertly designed to deliver precise, powerful, and efficient bass—ideal for car audio enthusiasts who prefer the clarity and control of sealed enclosures.

Engineered for audiophiles who value fast and accurate low-frequency response, the XAS12 features a fibre-reinforced paper cone with a rubber surround for enhanced rigidity, stability, and durability. Its 500W RMS power rating ensures strong performance, while the dual 4-ohm voice coils allow for flexible wiring—whether in single or multi-sub setups.

While many subwoofers struggle to balance impact with precision in sealed boxes, the Altum Series stands out by delivering deep, clean, and controlled bass that punches hard without distortion. Available in 10″ and 12″ variants, these subwoofers are tailored for those who demand both sound quality and reliability in a sealed configuration.
