TW3 thin-line technology

The TW3 builds on the core technology of JL Audio's TW5 thin-line subwoofers, combining a shallow mounting depth with excursion capability that exceeds that of the W3v3 series. If you need a standard-depth option, the JL Audio 8W3V3-4 W3 Series subwoofer is also available.

JL Audio's patented thin-line woofer technology uses a "concentric tube" structure built into the injection-moulded cone body. This supports the voice coil and a full annular spider, while allowing the large motor structure to sit further forward than in conventional designs — making the shallow mounting depth possible without sacrificing excursion.

The TW3-D8 uses a tab-ear mounting design to maximise cone area within its mounting footprint, and requires only a very small sealed enclosure volume.
