<p>The TS-W3002D2/4 subwoofers are designed to produce enormously powerful music. Just take a look at its super-heavy-duty construction, all designed to handle up to 3,500 watts max. Double-stacked magnets for higher power, and a step-up radial surround for superior control and long excursions. We used a constructed cast-aluminum basket for this sub. Add in our patented IMPP cone and you've got a monster sub that can handle whatever you want to throw at it.</p> |
