Soundbarrier SBLA-28SUB Dual 18″, Horn Loaded Sub-bass System

Product Description

. Description

The SBLA28SUB is a high performance subwoofer system. The SBLA28SUB can be flown or ground stacked and possesses high output capability with low frequency extension. Dual ultra-long excursion 18″ (460mm)/4″ (100mm) V.C. drivers are loaded face-to-face in a folded horn design to augment the SPL output. The rear of the driver is reflex loaded to extend the LF output to below the natural cut-off point. This technique combines the high efficiency of horn loading with the extended low frequency response of a reflex enclosure allowing such high output SPL for and a more compact enclosure.

The proprietary rigging system of the SBLA28SUB is directly compatible with the SBLA12. It is quick to assemble and allows a wide range of array curvatures. All cabinet rigging hardware is integral and remains captive in transit.

The SBLA28SUB is constructed from multi-laminated birch ply and fitted with generously sized handles. To resist the ingress of water, the LF driver cone is treated with a waterproof lacquer.
