XCELSUS XAS10 Ultra Series Subwoofer

The XAS10 – ALTUM Series 10″ Subwoofer by Xcelsus is engineered to deliver efficient, accurate, and powerful bass—perfect for audiophiles who prefer the clarity of a sealed enclosure.

With a 500W RMS power rating and dual 4-ohm voice coils, the XAS10 is easy to wire for single or multiple subwoofer setups. Whether you’re upgrading a factory system or building a high-end install, the XAS10 fits perfectly into a 15-liter sealed box, offering tight and natural-sounding SQ bass.

Unlike many sealed-box subs that sacrifice impact for clarity, the Altum Series stands out by delivering clean, hard-hitting bass that maintains fidelity at all volumes. Designed with a fibre-reinforced cone and durable rubber surround, it ensures reliable performance with minimal distortion—even under demanding conditions.

For those seeking compact size, sound quality, and uncompromising precision, the XAS10 is the ideal subwoofer solution from Xcelsus.
