Sound + Design

Hydra is a horn-loaded subwoofer characterized by the development of the circular sections and its length that guarantee the perfect loading of low frequencies in sensitivity, depth, control and SPL expressed by the usage of few watt.
The most common subwoofers on the market (wooden box) are horn loaded speakers with several internal turns, sections not optimal and reduced develop length. Therefore leading to lower sensitivity,several reflections that creates distortions, ripples and loading not optimized.

Thereby involving:
• They need for corrections by DSP
• Mechanical stress caused by the excursion of the transducer that creates more distortions
• A huge amount of power needed by the amplifier to obtain SPL.
Hydra starts from 110dB 1W/1m in continuous power by 3400 W, reaching peaks of 145 dB, using a single hi-quality transducer of 18 “, all of this with a quality and a perception of the bass frequencies deep and controlled, with a reduced excursion of the 18” transducer that decrease distortions and mechanical stress. The structure is rigid, very light (considering the whole weight and the rate dB/Kg) and scenic.
The Scorpion DP version is compact compared to the SP version, without loosing performance.
