*Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied. **Efficiency (1W/1m) is not an accurate indicator of a subwoofer’s output capability and should not be used as a comparison to other subwoofers to determine which one is “louder”. ***Re (DC resistance) is measured with the voice coils in series, for parallel-wired specification divide Re by 4. All other specifications remain the same.

GRILLE RECOMMENDATIONS		If you would like to put protective grilles on your W3v2, please make sure
		they allow sufficient clearance for the suspension of the speaker to operate
		properly (many “universal” grilles do not).
		One way to be sure is to use the grille mesh inserts engineered by JL Audio
		for your woofer. These sturdy steel mesh inserts mount securely into the
		rubber gasket of the W3v2 and offer ample clearance for the suspension.
		Ask your dealer for details and pricing.
