More bass. More power. Greater flexibility. Get powerful, punchy base in your car - from the pedigree of world record-breaking subs. The TS-W308D4 sub features a combined Aramid and Basalt fibre cone, which makes the body ultra-rigid, yet lightweight, giving you low distortion and powerful bass at high sound press levels. Greater flexibility is possible, too. With a 4Ω dual voice coil, you can opt for a 2Ω or 8Ω set-up (provided that there is correct power matching between the sub and your amp). Wiring and installation is made easier with one-sided terminals. And you can enhance the look (and protection) of your sub with the addition of an optional 3-spoke grill. The TS-W308D2 is recommended for enclosed use and is also available as a 2 Ω dual voice coil model.
