The Spirit SUB 12 is built around a custom-developed 12" long-stroke driver optimized for both home cinema impact and musical precision. Designed in-house by XTZ, the driver delivers deep, dynamic bass while maintaining accuracy and control.
Long-stroke pulp cone
A custom long-fiber cone provides ideal stiffness-to-weight ratio for fast response and low distortion, even at high excursion. Ensuring clear and undistorted playback, even under pressure.
High-performance motor system
A powerful magnet structure and 400W amplifier ensure linear motion and clean, distortion-free bass that stays controlled even at high volumes.
Engineered suspension
A ventilated spider and rubber surround support long-stroke movement without compression, while a high-temp voice coil and reinforced motor ensure control and impact under heavy load.
The Spirit SUB 12 uses a powerful and efficient Class-D amplifier derived from XTZ’s SUB 17 series, delivering high output with minimal heat.
Powerful output
200W RMS and 400W peak provide tight control over the woofer, combining cinematic slam with musical precision.
Low power consumption
The class-D technology in this amp draws less than 0.5 W in standby and only 12 W in idle, maximizing efficiency and minimizing wasted energy.
Exceptional Headroom
A specially developed PCB layout ensures clean clipping behavior, giving the amplifier high headroom and stability even during complex music or heavy bass effects.
The cabinet plays a key role in bass precision. Spirit SUB 12 uses a thick MDF enclosure with substantial internal damping to minimize coloration.
Thick front baffle
A 25mm thick MDF front baffle and 18mm thick side walls, contributes significantly to its stability.
Minimized Resonances
Internal bracing and generous damping make the cabinet rigid and acoustically inert, minimizing resonance and allowing the driver to perform with precision and control.
Premium matte finish
Multi-layer lacquer in matte black or matte white blends into any space with a clean, furniture-grade look.
The Spirit SUB 12 includes multiple tuning options to tailor bass performance to your space and content.
