MONSTROUS BASS WITHOUT DISTORTION
The front-firing 12.6″/32 cm driver, built with an oversized magnet and vented voice coil, moves serious air while remaining completely controlled. The heavy-duty MDF enclosure is airtight and braced internally to eliminate resonances.
CLASS D AMPLIFIER WITH SMART LIMITER
A powerful Class D amplifier provides 550 watts continuous power and over 1,100 watts peak. Integrated DSP manages equalization and peak limiting, ensuring distortion-free operation at reference levels—even in large rooms.
2 PASSIVE RADIOTORS FOR DEEPER BASS
The SUB300-THX features a 12.6″ / 32 cm high-performance long-throw woofer and two matching 12.6″/ 32 cm passive radiators, delivering deep, extended bass without background noise. Its non-ventilated design eliminates airflow noise even at high volumes, while the compact enclosure ensures easy, unobtrusive integration into any home cinema system.
PREMIUM DESIGN
Like the rest of the range, the SUB 300-THX features a front baffle finished in deep black silk matte lacquer, complemented by an anthracite brushed-metal textured body. The magnetically attached front cover and passive radiator coverings ensure a clean look without compromising sound transmission. A low-reflection brushed titanium-look metal logo adds a subtle premium touch.
KEY FEATURES
OUR TECHNOLOGIES
ENGINEERED FOR DEEP BASS
The Magnat Cinema Ultra subwoofer is driven by a powerful 12.6″/32 cm long-throw woofer and two matching passive radiators, all featuring low-loss rubber surrounds and multiple-coated paper diaphragms for optimal rigidity and control. Housed in a flow-optimized die-cast aluminium basket, the woofer is powered by a double-magnet high-power drive system with an inductivity control ring, ensuring extremely low distortion even at high output levels. Its multiple-ventilated voice coil and extra-large linear excursion allow for high resilience and maximum signal purity. Firmly anchored with eight screw fixings, the entire assembly delivers tight, extended bass with exceptional clarity and impact.
CLASS D TECHNOLOGY
The SUB 300-THX is powered by a custom-developed Class D high-performance amplifier, delivering exceptional output with minimal heat and a compact footprint thanks to advanced Class D technology and a switch-mode power supply. A real-time limiter ensures clean, distortion-free bass by preventing overload, while active frequency range equalisation meets the stringent THX® Ultra2 standards. With THX® and stereo inputs, plus adjustable volume, phase, and crossover frequency (in stereo mode), it offers maximum flexibility for any setup. Convenient features like auto stand-by, automatic power-on, and ultra-low stand-by power consumption below 1 watt complete this high-efficiency design.
SOPHISTICATED CABINET DESIGN
The Magnat Cinema Ultra subwoofer features a robust, braced MDF enclosure with a thick, low-resonance 45 mm baffle for superior acoustic stability. The closed cabinet design eliminates background noise even at high volumes, meeting the strict THX® Ultra2 standard.
Detachable fabric covers and large resonance-absorbing feet with central screw holes for optional spikes complete the sophisticated design.
