Overview

DS18 EXL-X12.2D 12" Cast Frame DVC Subwoofer 2 Ohm

When you need high output and ground shaking bass, then look no further than the EXL-X12.2D 12" cast frame subwoofer from DS18. This massive subwoofer combines high power handling and excellent excursion capabilities to deliver remarkable output with low distortion. 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-X12.2D a powerful subwoofer that will take serious use and abuse while continuing to provide incredible performance.

The design of the EXL-X12.2D makes it perfect for vented designs. Vented enclosures will result in more output and maximum low frequency 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.
