KSD A500 Stereo Pair
The A500 is the primary monitor in the KSdigital A-Class, featuring a double 10“ bass and a horn-supported tweeter. It functions as a classic 3-way reference monitor, providing high sound pressure and accurate tonal reproduction through KSD’s time-correct sound conversion. It is available in black and cherry.

The A500 offers an unprecedented level of resolution in the sound image. Our phase-linear FIRTEC(TM) filters create a precise virtual stage in the panoramic image, setting it apart from other monitors in its class. The dedicated 3″ dome midtone driver brings exceptional detail and clarity to the placement of vocals in the mix.
Similar to the legendary ADM20, the A500 ensures that all frequencies reach the sound engineer’s ear simultaneously, without any delay. This tonal neutrality and timeliness make it suitable for use in all stages of professional production processes, whether it be recording, as a mixed monitor, or as a final reference in mastering.
The two 10″ high-performance bass drivers produce ample bass energy even in larger control rooms, while the patented 1″ compression driver delivers outstanding dynamics and resolution across a wide and deep sweet spot. The 80°x60° horn ensures a linear frequency response, effectively concealing any housing edges and resulting in a remarkably quiet sound.
