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 combina-
tion provides optimal cone loading 
and heat dissipation. Further 
loading and dispersion is controlled 
through a precision phase plug.

Heat-resistant midrange

 

Midrange requencies between 

450Hz and 2.2kHz are reproduced 
by an eight-inch midrange speaker 
that provides 106 dB 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 assemb-
ly and magnetic structure is poor 
and failure rate from heat fatigue is 
high. The SL412 midrange dissipa-
tes heat passively through the use 
of a massive aluminum heat sink. 
When combined with the SL3000 
amplifier unit control electronics, 
the system provides high output 
levels safely and consistently over 
infinite periods of time and dramati-
cally 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 transdu-
cers 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 repositi-
on 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.

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 system control and amplifi-
cation system.
 

The SL412 Loudspeaker system 

benefits from being designed 
exclusively to operate above 60 Hz. 
By optimizing the ideal operating 
band pass of each system compo-
nent, the SL412 can achieve 
extremely high output levels 
consistently and safely. 

Active-driven by the SL3000 unit

 

Power, electronic crossovers, 

phase alignment, equalization, time 
correction and speaker protection 
are provided within the SL3000 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 reinforce-
ment technology, yet locates the 
electronics in an easy-access 
rackmount module. 
 

Together, the SL412 and 

SL3000 unit deliver the highest 
dynamic range of any system 
currently available, providing new 
levels of clarity, depth and resoluti-
on.

Advanced compression driver

 

 

KV2 Audio’s transducer partner, 

18 Sound in Cavriago, Italy, manu-
factures 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.
