This quality-built woofer offers double the power handing of the previous generation, with a stunning 250W RMS/1000W peak. This subwoofer offers several remarkable features. With an impressive 500 watts of peak power handling, the CS1004T outperforms the previous generation by a factor of two. Its lightweight polypropylene woofer cone is used to ensure maximum woofer efficiency. The CS1004T also features a progressive spider, which provides better control at excursion limits than does a linear spider; the benefit is reduced distortion at high output levels. Its bass-reflex tube exhibits high efficiency and reproduces powerful bass, even in combination with small amplifiers. And it has a clean-looking design, with a stitched-in JBL® logo.
