The S4VA are the most affordable ADAM monitors to incorporate the A.R.T. midrange unit, which translates the advantages of this technology to frequencies down to 600 Hz. The benefits of this driver are numerous: it frees the midrange from typical coloration caused by cone drivers, it has excellent dispersion, and it has the ability to create a natural sound field unsurpassed by any other loudspeaker. The S4V´s capability to create realistic 3-D soundscapes makes them the ideal choice for the discerning surround sound engineer.
