Audison APX 4 coaxial speakers (100 mm).

Audison APX 4 (PRIMA sērija) 2-joslu koaksiāla akustika 4" (100 mm).

APX 4 features a concentric coaxial tweeter: with one single point of sound emission it’s possible to obtain a consistent in-phase response, with consequent reconstruction of the acoustic scene comparable to a system of separate woofer + tweeter. 
The 4" cones surround featuring the exclusive shallow “Triple Wave” profile, for maximum excursion linearity.
