Long throw enclosures
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.
