The VH Infra218R is a special Infra-Bass unit housing two long excursion 18in. direct radiating transducers mounted in a two separated bass-refex tuned enclosures.
It has been expressly designed to be combined with the VH e-motion Series (VH MH210H / VH Bass215H / VH F12H) as perfect integration extending the system response down to 25Hz. 
The identical shape cabinet allows the perfect ground stacked configuration.
Particular is the "V" shape design that allows to obtain a larger unique reflex port exactly in the cabinet middle, maximizing the system efficiency in the lower frequency response.
The reflex port center alignment more increases the system performances because of its exponential front loading path.
The result becomes more significant specially when coupling several units in large sub array configuration.
Thanks to the bass reflex differentially flared design the optimized vented port reduces turbulence and port noise at high levels while also increasing LF efficiency and extending the response down to 25Hz.
Special is the speaker design, it allows to achieves an exceptional benefit controlling the lower frequencies response and significantly reducing the energy radiating towards to the rear. 
Thanks to the system efficiency the VH Infra218R is capable of delivering a high standard SPL output still maintaining a great linearity in the frequency response.
The system ability to control the exceptional transducer excursion keep really low the total harmonic distortion level.
Significant construction criteria, combined with the latest technologies and the innovative materials, ensure a great reliability. 
The VH Infra218R cabinet is constructed from marine plywood and has an impact and weather protected PCP (Polyurea Cabinet Protection) finish. 
It can be as well matched with all the most challenging Full-Range and Line Array Loud Professional systems significantly boosting their LF extension.
Applications: Large Open Air Venues, Arenas, Stadiums, Theaters, Conference Halls, Concert Halls, Large Scale Discos & Clubs.
