Product Description

The Sound Barrier SBLA45 is a compact, lightweight Variable Dispersion Speaker system that is ideal for a wide variety of venues and applications, including Auditoriums, houses of worship, banquet halls, community centers, health clubs, ball rooms, dance halls and more. While the traditional full-range loudspeaker is able to provide good sound coverage, the design’s sound coverage is difficult to control. The SBLA45 offers more control of the Sound Coverage with four easily adjustable dispersion angles – 60, 45, 30 and 15 degrees – that can be adjusted in just a matter of seconds.

No venue is exactly the same and a variety of venues pose serious problems for Sound Reinforcement. The SBLA45 does not have a problem with the comb filter and interference effects often encountered with other loudspeaker speaker designs. It can therefore produce more low frequency output even when mounted on the wall or ceiling.
