The la-510 is a line array column system comprised of ten 5" neodymium magnet transducers housed in an high quality plywood speaker box. The ten closely spaced cone drivers provide true line array characteristics - phase coherence, low distortion and focused listening in both the near field, and at a distance from the speaker. La-18 is a 18"subwoofer, specifically designed to reproduce deep bass frequencies with maximum efficiency, speed and impact. It is also ideal for reproducing the concentrated energy of contemporary music environments such as discos, clubs and outdoor shows where extreme level of bass is required.
