A215S is a reflex subwoofer that consists of a couple of 15” cone drivers. It is suitable for all kinds of languages and sound reinforcement applications, as well as varies of fixed installations. It can expand the low frequency response range when working together with full range loudspeakers of LA series.

LA215S subwoofers utilize the brand-new woofers to avoid airflow noises which may occur in ordinary ones when work with ultra-high power, and it’s a vented, small volume enclosure designed with a prepositive horn, which reduces the group delay of the LF and ensure the speed impact in the LF. The big volume inverted tube increases the output of the subwoofer, and decrease the non-linear distortion, so as to maintain the transient response, speed, and thickness in LF.
