Introducing the EPAK2500

The EPAK2500 is a four-way, active control 
and amplifiation system specifically designed 
for the KV2 Audio ES Series™ modular loud-
speaker systems. It houses all signal processing 
and amplification as well as providing control 
for six different subwoofer cabinet configurati-
ons, powered by the internal subwoofer 
amplifier, along with providing control signal 
to an external VHD3200 subwoofer amplifier  
to power further subwoofer cabinets if 
needed.

Unlike most other speaker manufacturers, 
KV2 Audio is equally expert in electronic 
design - in fact, we’re fifty-year veterans at 
building rugged, high-current power amps.
When you’re able to perfectly match an amp 
with a transducer, you unlock incredible 
performance that is impossible with passive 
systems. The amplifier can perfectly handle 
the impedance swings of the transducer. It 
can deliver exactly the right amount and type 
of power. Reliability goes up dramatically as 
does sound quality.
Each amplifier in the EPAK2500 perfectly 
compliments the transducers it’s coupled to. 
They are therefore very different from each 
other with respect to construction and purpo-
se.
Mid / High Amplifiers. Both the mid and high 
frequency amplifiers inside the EPAK2500 
are Class AB, Push-Pull amplifier circuits using  
(MOSFET) Transistors output stage devices. 
The entire performance strategy for this type 
of design is based on producing the lowest 
inter-modulation distortion possible and the 
highest audio quality in the critical mid and 
high operating bands. Both amplifiers are 
coupled to the mid/high drivers through 
transformer balanced speaker outputs. 

Mid Bass and Low Frequency Amplifiers

For these frequency ranges, we’ve selected a 
very high efficiency and refined low frequency 
amplifier topology.
The unique part of the design is in the voltage 
amplifier’s ideal method in supplying current 
to the output stage. It’s based on a switcher 
design that supplies current both in its on and 
off position  and superior bass reproduction 
quality. The system is also 95% efficient 
lowering typical amplifier losses and elimina-
ting the need for forced cooling systems.

The amplifier compliment inside the 
EPAK2500 is as follows:

High Frequency - 100-watt, Class AB, push pull,  

 

          low intermodulation design

Mid Frequency  - 200-watt, Class AB, push pull, 

 

          low intermodulation design

Mid Bass           - 600-watt,  high efficiency, 

 

          current-enhancing switch mode 

  

          with Linear Active Filter.

Subwoofer        - 1600-watt,  high efficiency,  

           

          current-enhancing switch mode 

  

          with Linear Active Filter.

Introduction

NOTE

NOTE:

For the best performance where 
possible use only KV2 Audio 
components, any other compo-
nent may negatively affect the 
sound quality.
