Main characteristics:

1. Construction and components :
   • A two-way bipolar system with Wide Dispersion Surround Technology (WDST), which combines the benefits of diffuse and direct sound radiation.
   
   
   • Two 5.25" (13.3 cm) woofers with Ceramicallic cones deliver deep bass and low distortion.
   
   
   • Two 1" (2.5cm) titanium dome compression tweeters, each coupled to a 5" (90° x 60°) Tractrix square horn. The tweeters are angled to each other to minimize interference and create a wide soundstage.
   
   
   • The closed-type body is made of MDF with professional tongue and groove assembly (dado and rabbet), which ensures strength and reliability when mounted on a wall or ceiling.
