Comprising of an upgraded subwoofer, the new driver is capable of up to 18mm of displacement for ultra clean low frequency bass. Class leading driver efficiency requires less power from the amplifier, reducing thermal compression and flux modulation. Rated to 500W RMS, this driver means serious business.


The side mounted bass reflex design further improves the efficiency of the subwoofer by +3dB, and extends the frequency response of the woofer to below 27Hz at -3db! A high quality dual flared 4" port is used to eliminate turbulent port noise and port compression at high volumes.


Powering the subwoofer is a Class D 500W integrated plate amplifier. Containing a fully variable level, crossover frequency and phase controls; system integration and room optimisation are a breeze. The class D design is extremely efficient, reducing power requirements and keeping the amplifier cool to touch even at high loads. The auto-on/off feature switches the unit off when not in use.


Overall, the Summanis Shiva 12 is an ultra high quality subwoofer that not only looks beautiful, but delivers exceptional performance.
