Klippel optimization has been used in the design of Hydrogen SPL elements. During the 10-hour testing, the behavior of the element is studied with numerous measurement results, and thus the weak points and problems that require improvement are found already in the early design phase. The element is fired with up to four times the power compared to its power duration. The end result is an element with a very even impedance response, i.e. it receives power well at all frequencies, has good sensitivity and withstands power properly.

If you want to play LOUD, the Hydrogen SPL is an excellent choice for an element. A solid and well-breathable cast frame keeps the element together and allows the subwoofer to breathe properly through the frame. Functional voice coil ventilation and sufficiently robust voice coil keep the operating temperature of the coil correct even during heavy use. The double lower suspension controls the movement of the cone and the fastening of the upper suspension and the cone, which is secured by stitching, can withstand even a more violent trajectory.
