The Pioneer TS-W311D4 represents several recent innovative advances in speaker technology which improve performance and durability. It all starts with the TS-W311D4’s IMPP composite seamless speaker cones. Lightweight but built incredibly tough, their seamless design helps to prevent tears and other failure at high volume levels – but it’s not just about durability. Pioneer’s seamless cones also provide powerful, magnificently accurate bass response thanks to their industry leading design.
The Pioneer TS-W311D4 also includes Pioneer’s elastic polymer dual layer surround; this is a first in speaker design and contributes to the speaker’s exceptional response at any volume as well as its structural integrity and lightness. As part of the Pioneer Champion series, the TS-W311D4 offers louder and more faithful reproduction of bass frequencies through its unique speaker cone design which features a 14% larger surface are compared to traditional subwoofer cones.
Flexibility is another important feature of the TS-W311D4. It can be wired at either 2 ohms or 8 ohms depending on your amplifier. Additionally, the speaker terminals are all placed on one side to make installation easier.
Along with its 4 layer copper voice coil and durable suspension and it’s easy to see why the Pioneer TS-W311D4 is rapidly becoming a favorite among audiophiles who don’t think that high quality audio has to end at the car door.
