Overview

DS18 EXL-X8.2D 8" Cast Frame DVC Subwoofer 2 Ohm

When you need high output but want to save space, then the EXL-X8.2D 8" cast frame subwoofer from DS18 is the perfect solution. This compact subwoofer combines high power handling and excellent excursion capabilities to deliver remarkable output for its size. To improve reliability, the treated foam surround is stitched to the rigid reinforced paper cone eliminating a common failure point for many high excursion drivers. For high power handling, the 4-layer 2-1/2" voice coils are wound on an aluminum former and vented extensively to dissipate heat while lowering power compression. The strong motor assembly consists of dual stacked magnets allowing ample voice coil clearance for high excursion without bottoming out. Holding everything together is a solid cast aluminum frame built to handle the stress of the difficult car audio environment. This rugged construction makes the EXL-X8.2D a powerful compact subwoofer that will take serious use and abuse while continuing to provide incredible performance.

The design of the EXL-X8.2D makes it suitable for a variety of designs. A sealed enclosure or infinite baffle installation will produce accurate and controlled low end for systems designed for sound quality. Vented enclosures will result in more output for higher SPL. Dual 2 ohm voice coils allow for a variety of wiring configurations to achieve maximum power from your amplifier.

Note: Specifications shown are with the voice coils wired in series for a 4 ohm load.
