Box size for Kicker L5's

Specifications

Power Handling: When the subwoofer is mounted in a sealed enclosure that has a volume from 0.66 cu/ft to 1.0 cu/ft, each coil can handle up to 225 watts RMS (450 watts peak). When the woofer is mounted in a vented enclosure, its power handling varies depending upon the size of the enclosure. In a 1.25 cu/ft vented enclosure, each coil can handle up to 250 watts RMS (500 watts peak). In a 1.75 cu/ft vented enclosure, each coil can handle up to 262.5 watts RMS (525 watts peak). In a 2.25 cu/ft vented enclosure, each coil can handle up to 275 watts RMS (550 watts peak).

Recommended Sealed Box Volume: When mounted in a sealed enclosure, the woofer delivers massive amounts of high-impact bass and can be driven with punishing levels of amplifier power.

• Compact (minimum enclosure volume): 0.66 cu/ft; each coil can handle up to 225 watts RMS (450 watts peak)
• SQ (maximum enclosure volume): 1.0 cu/ft; each coil can handle up to 225 watts RMS (450 watts peak)

Recommended Vented Box Volume: The vented enclosures incorporate massive slot-loaded ports with ultra low air velocity and hard-hitting bass. These are not your traditional port tubes; the slot-loaded ports are integrated into the enclosure design. Compact enclosures have increased bass efficiency over a sealed enclosure, yet can still fit in tighter applications. Street Bass is a medium sized enclosure that will kick out bass that can be heard from blocks away. SPL/Deep Bass is a large enclosure with high efficiency that will deliver the output needed to win SPL contests and produce the bass that goes down to the lowest frequencies.

• Compact: 1.25 cu/ft; 2.5"x11.25" port opening; 19.75" port length; each coil can handle up to 250 watts RMS (500 watts peak)
• Street Bass: 1.75 cu/ft; 2.75"x11.25" port opening; 17.75" port length; each coil can handle up to 262.5 watts RMS (525 watts peak)
• SPL/Deep Bass: 2.25 cu/ft; 3"x11.25" port opening; 18.0" port length; each coil can handle up to 275 watts RMS (550 watts peak)

Note: The power handling specifications listed with the vented enclosure recommendations apply only when a 25Hz, 24dB/octave subsonic filter (sold separately) is used with this woofer. If a subsonic filter is not used, the power rating will decrease and excessive port noise can occur. 

Cutout: The woofer will not mount in a standard enclosure with a round cutout. Instead, the woofer must be mounted in an enclosure with a 9.198"x 9.198" square opening.
