For almost 25 years the X-act is proving to be a most reliable, optimum blend of faithful audio reproduction and versatility.

The X-act can immediately be recognised by its perfect voice reproduction. This is because the human ear is extremely sensitive to deviations in this vital part of the frequency spectrum.

The X-act combines a lightweight TSG moulded, ergonomical cabinet construction with aluminum reinforcing and light loudspeaker assemblies. The resulting 16kg make the X-act a featherweight to handle but a suffciently stable floormonitor. The X-act always excels. As an elegant F.O.H. Systemm, an independent distributed system or any type of infill. Last but not least the X-act is near perfect floor monitor.

The S.A.L.C(Single Audio-Logic level control) speaker management is proprietray RMS based gain riding circuit which maintains the tonal balance of the sound as preceived bt the human ear. Especially at high levels.

State-of-the-art modelling techniques and acoustic simulation programs dictate rounded cabinet shapes, manifold reinforcing ribs and no parallel surfaces. A shared wave-guide loads the 1" and 10" drivers. The result is minimal coloration in the "speech-band" over a wide. yet stable sweet listening spot.

An optional quick release gigbag is available if transport has to be done on the backseat or

turnk of a luxury car.
