Next in line will be a 9-inch passive subwoofer in a very compact 8.5 liter aluminium enclosure. This 8 Ohm subwoofer will be suitable to drive in parallel and can be stacked. Simulated f10=26Hz, Qtc 0,71.
Update [06/05/2024]: The LD230 CRA08M is undergoing an update. The motor will be improved with a little more BL, less distortion, less flux modulation. When the new model is available we will continue with the development of this subwoofer.
