Helix Pure series High-End 2-way standalone kit.
The midbasses in this series feature a paper-composite cone that provides a decent kick while maintaining excellent sound quality.
The trebles are made of really high-quality silk calottes for which aluminium mounting pods ( PR ATP25 ) are available as an option.
The stylish ″Flex-Crossover″ split filters can be split in two, with separate filters for the treble and midbass, making it easier to position the split filter.
In addition to its outstanding sound characteristics, the PR K165.2 also impresses with its stylish design. In particular, the high quality components and the optional aluminium cabinet ( PR ATP25 ) for the tweeter make this system a real eye-candy.
