NEXT-proaudio HFA Series systems are built in Europe (Portugal) by NEXT-proaudio, according 

to the highest standards and thoroughly inspected before they leave the factory. When unpacking

HFA SUBWOOFER SERIES OVERVIEW  

 

The HFA speaker series are fully powered PA systems, designed to deliver high output and 

dynamics, extreme linearity and fidelity for unrivalled performance at a very competitive price. 

Entirely manufactured in Portugal, the HFA speaker series uses superb quality custom made 

components, loading birch plywood enclosures coated by a scratch resistant textured paint to assure 
an outstanding performance and durability. 

The integration with the new DPAmplifier modules with up to 2200 Wrms, and the advanced 

digital signal processing, set a new standard for distortion, noise and thermal efficiency. A surprisingly 

simple handling concept lets you plug in and play straight away. Configure the system by selecting 

the right preset and let the system do the rest.  

The HFA112s, HFA115s and HFA118s have the ability to power an external passive satellite 

up to 550Wrms keeping 1100Wrms for its own power. The HFA118sHP and HFA115sHP do not have 

the ability to power an external passive satellite but are able to handle up to 2200 Wrms of power.
