AD Designs speakers and amplifiers are hand assembled, incorporating cutting-edge technology and utilizing superior state-of-the-art components built to exact tolerances and specifications. All of the components used on our subwoofers are the results of over 60 years of continuous development. Each technical detail is shared from the 4000 series down to the 1000 series. The only thing different between the series is the motor (magnet) size and the voice coil size. So, you can pick the right subwoofer that's right for your power handling needs without sacrificing any state-of-the-art feature. |
