Basic feature of this surprisingly light (taking into account 1000W which it offers) speaker is the simplicity of transformation full range frequencies: from low and strong bass, across clear middle, till subtle but dynamic top. All of that in very balanced proportions and excellent directivity. Impedance of 4 Ohm provides wide range availability of amplifiers. Because of listed features GD3-1012 PRO is a excellent solution in the simple, mobile sets without subwoofers as well as as satellite in more complex systems.
