SL412 · Technology
The
SL412
is a 3-way high output, active-driven, wide dispersion loudspeaker module. It is designed as part of a sound
reinforcement speaker system that includes the SL3000/SL3000D system control and amplification system The SL412
Loudspeaker system benefits from being designed exclusively to operate above 60Hz. By optimizing the ideal operating
band pass of each system component, the SL412 can achieve extremely high output levels consistently and safely.
Active-driven by the SL3000/SL3000D unit
Power, electronic crossovers, phase alignment, equalization, time correction and speaker protection are provided
within the SL3000/SL3000D unit. This "one plug in, one-plug-out" system ensures fast, easy set up and complete
control. It gives you the benefits of active sound reinforcement technology, yet locates the electronics in an easyaccess
rackmount module. Together, the SL412 and SL3000/SL3000D unit deliver the highest dynamic range of any system
currently available, providing new levels of clarity, depth and resolution.
Advanced compression driver
KV2 Audio's transducer partner, 18 Sound in Cavriago, Italy, manufactures and co-develops all SL412 components.
The compression driver is a 3-inch nitride- titanium diaphragm design, featuring a complex geometry phase plug that
dramatically lowers distortion, eliminates ring modes and provides clearer, ripple free performance.
Mid/High horn design
The SL412 features a mid/high integrated horn design with a number of unique features. The horn design is based on
constant directivity geometry with an emphasis on maintaining low transducer compression ratios, high output and
wide dispersion (110° x 40°). The midrange speaker is fixed to a large aluminum heat sink which is attached to
a precisely designed midrange "chamber". The combination provides optimal cone loading and heat dissipation.
Further loading and dispersion is controlled through a precision phase plug.
Heat-resistant midrange
Midrange frequencies between 450Hz and 2.2kHz are reproduced by an eight-inch midrange speaker that provides
106dB of sensitivity (1 watt / 1 meter) when coupled with the integrated horn. The magnetic motor assembly features
a Trans Coil 3" diameter voice coil assembly and extensive use of neodymium. Because of the limited linear movement
of most midrange transducers - usually 2-3mm - ventilation of the voice coil assembly and magnetic structure is poor
and failure rate from heat fatigue is high. The SL412 midrange dissipates heat passively through the use of a massive
aluminum heat sink. When combined with the SL3000/SL3000D amplifier unit control electronics, the system provides
high output levels safely and consistently over infinite periods of time and dramatically reducing heat associated
transducer problems such as power compression and decreased dynamics.

Neodymium mid-bass transducer
The SL412 features a four twelve-inch neodymium mid-bass speakers with
front loaded bass reflex design. It is important to note that neodymium is not
a transducer panacea, as it cannot safely operate at the same typical operating
temperatures ferrite does. Using neodymium requires a profound understanding
of material science and finite element analysis to properly design a stable, high
force magnetic structure that functions correctly. 18 Sound and KV2 Audio
engineering jointly designed the twelve-inch mid-bass driver for the SL412.
The SL412 mid-bass transducers reproduces frequencies from 60Hz to 450Hz.
Used mid-bass transducers are very precise and fast with high sensitivity.
The high efficiency neodymium motor provides an extraordinary amount of force
that delivers complete control of the cone mass and a high overall weight loss.
Easy to set up
The SL412 is the ultimate, nice looking enclosure featuring a number of
ergonomically designed components that make it a light, small, and easy speaker
to set up and use. KV2 designed and tooled new cabinet handles for use in their
products. The two side handles make it easy to pick up and reposition the SL412
in a natural, instinctive manner. There are four industrial grade, internal braces
placed at each corner and one internal brace on the back. Corner braces are held
in places by four M6 and two M10 bolts, the back brace is held by two M6 and one
M10, providing a wide range of installation and suspension flexibility.
