Equipped with a robust Class D amplifier, Power Port technology and Time-Smart Phase Control , this subwoofer delivers balanced, impactful sound with unprecedented precision.
Its elegant cabinet integrates perfectly with Signature Elite systems and fits into any space.
Powerful 8 inch Woofer
The front-firing , 8-inch, long-excursion woofer produces deep, clear bass down to 28 Hz.
This feature allows you to perceive not only the sound, but also the bass vibrations, transforming the listening experience into a tangible emotion.
Acoustically Optimized Cabinet
The cabinet, reinforced with a system of internal supports optimized through FEA, reduces resonances and sound coloration to a minimum.
Thanks to its front-firing configuration and Power Port technology, the subwoofer guarantees accurate bass while significantly reducing subwoofer placement problems.
Intelligent Phase Control
With Time-Smart Phase Control , integrating the subwoofer with your other audio system components is simple and seamless. This control offers 360-degree phase adjustment, allowing for precise bass matching with your main speakers.
Clean and Detailed Sound
The use of an advanced 32-bit DSP processor, with filters that minimize group delay and precision limiters, allows for clearer bass and crisper transients.
The combination of these technologies ensures a balanced and natural sound, suitable for small spaces such as apartments or compact environments.
