Xcelsus Altum Series Subwoofers Sealed for Perfection

The Altum XAS10 subwoofer was designed as the perfect solution when wanting to upgrade your car audio system, with a more efficient, precise, and powerful bass reproduction.

A common question is always sealed or ported enclosure? For some of us the decision is hard but for other the question is not even a question. The XAS10 subwoofers appeal to those who tend to gravitate towards a sealed enclosure. The woofers come in either a 10″ or 12″ woofer with both having a Dual 4 ohm impedance voice coil. This makes them extremely easy to wire up by themselves or even when doing multiple woofers at one time. The Altum series subwoofers are rated 500W RMS giving you the right amount of power to really bring out the best in your car audio. They have been designed to perform their best in a sealed enclosure giving you that quick, precise, and efficient bass reproduction. Unlike other woofers made for sealed enclosure not only will these hit hard but they will hit cleaner than any other in its class.

They deliver incredibly good-sounding natural SQ bass & will play perfectly in a 15-liter box. If you need uncompromising precision bass and still need to save space, this subwoofer is the best possible solution from Xcelsus.
