The ESR215 is a 3-way high output, active-driven, 

full range Loudspeaker module. It is designed as 

part of a sound reinforcement speaker system 

that includes the ESR3000 system control and 

amplification system.

The ESR215 Loudspeaker system benefits from 

being designed exclusively to operate above 35 

Hz. By optimizing the ideal operating band pass of 

each system component, the ESR215 can achieve 

extremely high output levels consistently and safely. 

Active-driven by the ESR3000 unit

Power, electronic crossovers, phase alignment, 

equalization, time correction and speaker 

protection are provided within the ESR3000 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 easy-access 

rackmount module. 

Together, the ESR215 and ESR3000 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 

ESR215 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.

Wide dispersion horn

The ESR215 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 with 

precisely designed heat sink 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 400Hz and 

2.5kHz are reproduced by eight-inch midrange 

speaker that provides 108 dB of sensitivity (1 

watt / 1 meter) when coupled with the integrated 

horn. The magnetic motor assembly features 

a high temperature 3” (76mm) 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 ESR215 midrange dissipates heat passively 

through the use of a massive heat sink midrange 

chamber. When combined with the ESR3000 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 bass transducer    

  

The ESR215 features a fifteen-inch ferrite bass 

speaker with front loaded bass reflex design. Great 

advantage of the ferrite structure is long-term 

stability of parametres and relative resistances to 

high temperatures. 

The ESR215 bass transducer reproduces frequencies 

from 35Hz to 500Hz.  The bass transducer is very 

precise and fast with high sensitivity. The high 

efficiency ferrite 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 ESR215 is an aesthetically pleasing - looking 

enclosure featuring a number of ergonomically 

designed components that make speaker easy to 

set up and use. 

ESR215 features the two top handles for pick up and 

reposition with additional M10 suspensions point. 

There are six industrial grade, internal braces 

placed at each corner and one internal brace on 

the back. Corner braces are held in places by two 

M10 bolts, the back brace is held by two M6 and 

one M10, providing a wide range of installation and 

suspension flexibility.
