Description
The 8W1V3-4 is an 8" (20cm) subwoofer known for its high quality and performance. It is JL Audio's best-selling 8" subwoofer and is an excellent choice, especially when space is limited and amplifier power is moderate. With its shallow installation depth and compact motor structure, this subwoofer fits easily into many rooms where conventional 8" drivers would not fit. It offers excellent excursion characteristics and linearity to reproduce sub bass with impressive quality. The 8W1V3-4 utilizes several proprietary JL Audio technologies to ensure superior performance and reliability.
Features
- The 8W1v3 is an excellent choice when space is at a premium and amplifier power is moderate.
- It is characterized by a shallow installation depth (98 mm / 3.86 inches) and a compact motor structure so that it fits comfortably in many spaces where a typical 8-inch driver will not fit.
- As there is no pole ventilation, the rear of the motor structure can be attached directly to a housing boundary.
- Outstanding excursion characteristics and linearity make it possible to reproduce sub-bass with shock-like extension and quality.
- Several proprietary technologies from JL Audio enhance its performance and reliability.
- The 8W1v3-4 is best used with amplifier powers in the range of 50W - 150W and is optimized for operation in a compact, sealed housing of 9.90l.
