The DLF-406 is a compact dipole loudspeaker designed to augment the mid-bass performance of CLA Series line arrays in a biamplified or triamplified configuration.

It features four 6.5” drivers in separate sealed enclosures spaced to take advantage of the dipole cancellation effect in the 150Hz to 325Hz frequency range. Below this range, the loudspeaker behaves as a conventional low-frequency system. Its dipole behavior extends the vertical pattern control of CLA Series line array loudspeakers more than an octave and allows for increased system SPL.
