• Non-resonant, integrated ¾” MDF enclosures promote natural, uncolored sound and minimize sound spillover into
adjacent rooms.
• Available in two configurations: the LCR2/SUR2 four-woofer design for the largest home theaters, and the LCR1/SUR1
two-woofer design for home theater designs up to 3,000 cubic feet.
Micro-trim grille design
The new Sonance Cinema Series speakers feature Visual Performance grilles that effortlessly blend into the
home theater - letting you focus on the movie experience and not the speakers.
Coaxial midrange / tweeter drivers
The new Cinema LCR and SUR speakers feature a unique coaxial midrange/high-frequency driver. The
midrange driver features a low-profile cone that does not compromise the performance of the tweeter
mounted in its center. This arrangement results in extremely consistent off-axis frequency response that
provides the same reference-quality sound to every listener, not just those sitting in the “sweet spot”.
dual and quad woofers
The new Cinema Series speakers feature two woofers in the LCR1 and SUR1 and four woofers in the LCR2
and SUR2. In a typical installation, using single woofer speaker reflections off the floor and ceiling can cause
dips in the frequency response up to 6dB. With a dual woofer speaker, these dips are minimized since the two
woofers will be unequal distance from these reflective surfaces. In a dual or quad woofer speaker, 3dB is the
maximum amount of cancelation that can occur. This, combined with the coaxial driver, produces a speaker
with the highest degree of sonic accuracy and the lowest room placement sensitivity.
Laminated cones
The midrange and woofer drivers both have cones featuring a laminate of carbon fiber and Rohacell ® . These
two materials combine to make a cone that is very light, non-resonant and extremely stiff. Additionally, the
density of the cone material prevent sound produced by the backs of the drivers from being transmitted
through the cone material, a common problem with less dense materials.
Integrated ¾” medium density fiberboard (MdF) enclosure
All of the Cinema Series models feature an integrated enclosure made from ¾”-thick MDF. The enclosure’s
density and rigidity prevents sound leakage from the speaker’s rear, minimizing sound intrusion into adjacent
spaces. In addition, the MDF is non-resonant, which minimizes the sonic colorations that can rob film
soundtracks of clarity and impact.
Enclosure damping material
To minimize the transfer of vibrational energy from the Cinema enclosure to its surrounding wall, the inner
surfaces of the enclosure are lined with a visco-elastic dampening laminate. This damping material turns the
vibrational energy into heat which is then dissipated inside the enclosure.
die-cast baskets
All the woofer and midrange drivers feature custom die-cast aluminum baskets for maximum rigidity. These
baskets not only keep the placement of the voice consistent they are also non-ferrous and do not drain any of
the magnetic field away from the driver’s motor system.
