Main
Characteristics
|
 |
Direct
radiation, Bass-Reflex design |
|
Advanced
Technology transducers including
optimised cooling and all-weather cones. |
|
Precision cabinet construction to achieve light and high resistance cabinets. |
|
Wear-proof, bi-component exterior finish offering ultra-high anti-scratch protection. |
All these characteristics contribute to obtain the advantages and performance of a true Sub-Woofer, so important in a Line Array rig. Its benefits are positively noticeable in P.A. set-ups, as well as in fixed installations. The
ARSO-215 enclosure enhances the whole system with an extra low-energy input that is so important in today's music material, whatever the style.
The ARSO-215 is a rugged enclosure, which mounts two high power,
15" transducers in a Direct
radiation, Bass-Reflex configuration. With these advanced components the cabinet renders an astounding
effectiveness hard to match by any other cabinet of its class and size.
The cabinet is equipped with a protection front steel grille, coated with outdoor resistant compounds. It is fitted with heavy-duty skids permitting stacking in total security.
Integrated, side handles are provided for ease of operation.
The ARSO-215 Subs can be stacked in the required proportions under the flown units or in a centrally situated position under the stage level. Its Efficiency and Frequency Range vary and depend on the total number of cabinets used.
The horizontal coverage will be inversely proportional to the product of the length of the array and the concerned frequency. In this case between 20 and 80 Hz. Or put in a different way, the higher the number of cabinets, the better our directivity control and the more specific our pattern behaviour. Thus a medium/large assembly of subs in a Line Array rig is capable of producing large amounts of low-end energy.

The
ARSO-215 Sub-Woofer is a double 15" enclosure designed for the reproduction of the sub low frequency spectrum of sound with a very high quality reproduction. Its main purpose is sound reinforcement in set-ups requiring high SPL down to extreme levels with absolute fidelity. Typical applications include live concerts and all types of multi-media events.
Ergonomic handles are provided on the enclosures' side panels for ease of handling. Heavy duty skids protect the cabinet against normal work abrasion.
Heavy
duty castors are integrated in the base of
the enclosure to permit easy of transport on
site.
