The ACV subwoofers of the SPL Show series of the SW PRO range are the most technologically advanced subwoofers for low bass reproduction. The SPL Show Series subwoofers have a non-pressed cellulose cone to help prevent resonance, improve linearity and reduce distortion.

Their special basket, together with a protective rubber ring covering the magnet, reduces speaker vibration and makes a good subwoofer. SPL Show subwoofers have excellent electro-acoustic characteristics that can be installed in any type of cabinet. A powerful high-density Y40 magnet, an absolutely linear magnetic field and a very light and stiff voice coil provide powerful, clear, undistorted sound.

A design feature of the SPL Show subwoofers is the use of a dual voice coil. This allows you to significantly increase the flexibility of their connection. Using these speakers, you can choose the connection method and their number to fully exploit the capabilities of the amplifier to which you connect the subwoofers. Dual voice coil is double power, double efficiency, small body.

SWF PRO124D is designed for those vehicles that need useful boot space or sedan vehicles. Typically, these subwoofers are installed in the rear shelf of a car. In open-air, there is no delay inherent in hull design. Low frequencies are clear and juicy, since the bass dynamics is not interfered with by the compressed air in the box. No sound shielding from the rear seat. There is no need to set aside space for the box, which is also very convenient.
