Compression Terminals: The wire terminals are spring post
and will accommodate speaker wire up to 10 gauge.
CEA-2031 Compliant: Power handling for the L1-S410 conforms
to CEA-2031 industry standards, meaning the subwoofer has the capacity to handle
its 150 watt RMS power rating continuously.
Trim Ring: To improve the cosmetic look, a trim ring is included
that mounts over the flange of the woofer. When using the PVC trim ring the woofer
is first mounted with four screws, then the ring is placed on top of the woofer,
aligning the final four holes of the woofer with ring. The other four screws are
used for these holes to mount the ring and woofer to the enclosure. The trim ring
increases the mounting height of the woofer to approximately 1" and its diameter
Sealed Box: Lightning Audio recommends a sealed enclosure
with an optimum internal volume of 0.64 ft³ (from 0.5 to 0.85 ft³ is acceptable).
Sealed enclosures provide the most control over a woofer, will handle a lot of
power, and provide accurate sonic reproduction, making them suitable to all types
Ported Box: The recommended ported enclosure volume is 1.47 ft³
using one 3" diameter x 9.4" long port; this yields a tuning frequency of
38 Hz. Ported (or vented) enclosures typically provide better overall efficiency
than sealed so they are suitable for use with smaller amplifiers, giving you more
bass output from less power. However, this efficiency comes at the expense of very
low frequency output (below 32 Hz).
