L-Acoustics SB28

The SB28 contains two 18’’ direct radiating LF transducers integrated into a bass-reflex tuned enclosure. The specially
designed 18’’ transducers provide an exceptional cone excursion capability combined with low thermal compression
even at the very highest operating levels. The progressive profile of vents allows laminar airflow and reduces turbulence
noise. The combination of these characteristics provides a greatly improved +5 dB peak SPL output compared to the
previous standards.
