8.5" Midbass / Subwoofer speaker set
The Legatia™ L8 is a 215mm (8.5-inch) subwoofer/midwoofer driver to compliment a dedicated
three-way or four-way front stage system design. Like the Legatia™ L6 midbass, the Legatia™
L8 is a cone-type driver consisting of a treated pressed paper diaphragm with low moving mass
for fast, transient response. The cone design offers a wide dispersion pattern to make for
flexible installation and speaker location. However, because of this driver’s specific design
function as a subwoofer and midwoofer in expanded three- and four-way designs, its bandwidth
was purposely left more limited than that of its smaller siblings. However, some may endeavor
to incorporate the L8 into a strict two-way design with a large-format tweeter placed close to
the same location as the L8, or used in concert with the wide-bandwidth L4 midrange.
Like other Legatia™ midrange and midbass designs, you will find no composite or metal cone
materials used on the L8. The purpose for this design philosophy is to ensure a light moving
mass cone, and optimized Qms for door, floor-board, and kick panel mounting, to ensure
subbass extension without the need for a sealed enclosure. The light cone further helps to
make the L8 a transiently “fast” driver which accurately reproduces complex musical passages
with ease.
