ACV subwoofers of the SPL Show series of the SW PRO series are the most high-tech for reproducing low bass. 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 that covers the magnet, reduces the vibration of the speaker and makes a good subwoofer. SPL Show subwoofers have excellent electro-acoustic characteristics that allow them to be installed in any type of cabinet.

A powerful "Y40" high density 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 package.
