Solid, powerful, strong bass. The TS-WX306T bass reflex tube system is made from thick MDF for guaranteed strength and stability, and is tuned for impactful, robust bass sounds. The tube encloses a durable woofer that is equipped with a voice coil cooling system. This enhances heat dissipation from the core of the subwoofer, improving the frequency response and load capacity of the device. The patented lightweight, seamless IMPP cone from Pioneer ensures that the subwoofer can handle up to 1,300 watts. The woofer has a cylindrical shape that eliminates standing waves generated within the enclosure, thus preventing a decrease in bass performance.
