Description
The 10TW3-D4, is a 10-inch subwoofer from JL Audio that is one of the best-selling items in the TW3 series. With its remarkable technical features such as 400W output, dual 4 ohms and thin-line subwoofer technology, it has secured a top position in the industry. This subwoofer impresses with its shallow installation depth and high excursion, as well as its optimized performance for small enclosures. It also received an award from Car & Hifi 5/2013, which gave it a score of 1.4 and a "very good" price-performance rating.
Features
- Building on the core technology of JL's TW5 thin-line subwoofers, the TW3s offer a powerful combination of low installation depth and high excursion. They are even able to realize greater excursion than the W3v3 subwoofers.
- To enable this remarkable performance, JL Audio's patented Thin-Line woofer technology compresses the TW3's architecture through a "concentric tube" structure built into the injection-molded cone body. This structure supports the voice coil and a full-ring spider while allowing the large motor structure to be placed further forward in the speaker than conventional designs.
- The TW3 are optimized for small enclosures and feature JL's lug mounting design to maximize the cone area within their mounting surface.Â
- Very shallow installation depth (3.25 / 3.50 inches)
- Very low requirements for the volume of the sealed housing
- Very long linear deflection (0.60 in / 15.2 mm, one-way linear deflection)
- DMA-optimized motor designs
- Cast alloy frame
- Membrane made of injection-molded, mica-filled polypropylene
- Rubber surround
- Aluminum alloy dust cap and back cover with JL Audio logo
- Precision engineered in the USA at the JL Audio factory in Miramar, Florida, with global components
