The result of such meticulous attention to detail is the lowest coloration of any speaker in its class. Using Computational Fluid Dynamics, the port flare and profile of LS50 Meta’s patented off-set port is calculated to delay the onset of turbulence, and the flexible port walls prevent resonances from colouring the midrange.
