The Sound Anchor ADJ3 stands are designed to allow the engineer to correctly place two pairs of monitors behind his console. These stands allow independent height and tilt adjustment of both monitors. The ADJ3 stand is based on our proven ADJ1 stands and offers all of the performance benefits of them. The symmetrical 23" x 17" bases and the uprights are filled and damped from the factory. This makes the ADJ3 a very solid and stable support for your speakers. The speaker platforms are made of 1/4" aluminum which reduces the amount of energy that gets transferred into the stand. The Sound Anchor ADJ3 stands isolate the speakers from the console, each other and the floor which gives you a cleaner, more detailed and more accurate sound.
