5 SB28 SUBWOOFER ENCLOSURE
®
The L-ACOUSTICS SB28 subwoofer enclosure contains two 18'' direct radiating LF transducers loaded in a
vented bandpass configuration. The bass-reflex vents feature a progressive profile allowing for laminar airflow, thereby
improving output SPL and minimizing unwanted noise.
The 18" LF transducers employed in the SB28 feature high power handling capacity combined with low distortion and
thermal power compression. The nominal impedance of the SB28 enclosure is 4 ohms.
In a standard configuration the SB28 enclosure generates approximately an omni-directional coverage pattern.
The SB28 cabinet is made of high grade Baltic birch plywood with remarkable mechanical and acoustical properties for
improved long term durability.
