Advanced Driver Technology

At the heart of the SU18 sits a powerful 18-inch woofer designed for maximum excursion without distortion. This driver produces bass you can both feel and hear, with a wide frequency range that surpasses typical subwoofers.

A high-performance class-D amplifier powers the woofer, delivering exact power based on the audio signal. This precision control keeps bass tight and responsive, even at peak volume levels.

Sealed Enclosure for Natural Bass

Unlike many subwoofers that use ported cabinets, the Gravis SU18 employs a sealed enclosure (acoustic suspension). This design ensures tight, controlled bass without the boominess often associated with ported designs. The sealed box helps the SU18 blend seamlessly with your main speakers and maintain a natural tonal character.

The cabinet uses rigid MDF panels reinforced internally and lined with damping material. This construction reduces unwanted vibrations, resulting in transparent and dynamic bass reproduction.

Flexible Tuning Options of the Auer Gravis SU18

The SU18 features a comprehensive control panel that lets you tailor its performance to your room and listening preferences. Adjustable crossover frequencies, phase control, and volume settings enable perfect integration with your main system for a balanced sound.

Robust and Elegant Design

The Gravis SU18 pairs outstanding performance with a timeless, sturdy design. Its clean lines and minimalistic look fit effortlessly into modern interiors without distracting from the listening experience. The high-quality finish ensures durability and style.
