VH Sub121H is a special Sub-Bass unit expressly designed and engineered for lower frequencies response at the maximum SPL output.
The hybrid system configuration (Bass-reflex & Horn Loading techniques) houses a single 21in. transducer of a 4.5in. voice coil woofer, tuned in a Bass-reflex enclosure to extend the LF output to below the natural horn cut-off point.
This particular compound system combines the high efficiency and great impact of the horn loading technique with the low frequency extension of the Bass-reflex enclosure.
Two extra-large ports allow to further extend the system frequency response down to 35 Hz.
The benefits of this ideal combination ensure a superior sound impact along the most accurate lower reproduction.
Bass-punch is unrivaled and the incredible high SPL output makes the system extremely effective when providing sound to spacious outdoor environments. Longer distances are reached with ease!
Specially designed for large scale open air venues, smaller compared to VH Sub218H, 121H can also be used in indoor environments of large dimensions.
The use is strongly recommended whenever a great impact, accuracy and transients fast response become mandatory.
Significant construction criteria, combined with the latest technologies and the innovative materials, ensure a great reliability over time.
VH Sub121H cabinet is constructed from Birch-ply and has an impact and weather protected PCP (Polyurea Cabinet Protection) finish.
It can be as well matched with all the most challenging Loud Professional Full-Range and Line-Array systems, significantly boosting their LF extension.
Applications: Large Open Air Venues, Arenas, Stadiums, Theaters, Conference Halls, Concert Halls and Large Scale Discos.
