Urs M has constructed an active 3-way closed-box loudspeaker system with drivers
from Aurum Cantus and Scan Speak. The system is power and processed by our Coolback II 600

Specs of the close loudspeaker concept designed by Urs

This is the "simple" active loudspeaker system, no multiple bulky power amplifiers etc. filling half
the living room and yet Urs gets high quality sound - actually you only see a set of loudspeakers...
