Kicker L7R Série Manuel D'utilisation page 4

Do not install a port opening against a solid surface, such as an internal brace, back-panel or trunk wall,
seat or interior panel of your vehicle. The port opening must remain unobstructed. Use the smallest
dimension of the rectangular port as the minimum amount of space between the port opening and any
solid surface to insure unrestricted airfl ow.
If you prefer an ultra-smooth bass response, you should loosely fi ll your L7R enclosure with poly-fi l
stuffi ng. Ported designs will require covering the end of the port (located inside the box) with grill cloth,
chicken wire, or expanded metal to prevent the poly-fi l from exiting the port. The use of poly-fi l will slightly
decrease effi ciency, but will deepen and extend the low frequency output.

VENTED ENCLOSURE APPLICATIONS
L7R subwoofers will handle massive amounts of power in any of the recommended enclosures,
minimum or maximum. The smaller enclosures are best for use in limited-space applications. The larger
recommended enclosures will yield slightly more bass at the lowest frequencies.
