Laminar Venting

All current L-Acoustics loudspeaker enclosures with low-range capacities feature laminar vents which provide high SPL while eliminating turbulence noise. This technology was implemented for the first time in 2007 in the SB28 subwoofer, and has been included in K1, K1-SB, K2, SB15m, SB18(i/m), and the X Series.

“I am impressed by the power of the 32 L-Acoustics SB28 subwoofers driven by LA8. We have used the SB28 in cardioid configuration during the Radiohead tour and the results are impressive.”
