WIENER LAUTSPRECHER MANUFAKTUR WLM Franz S

Not only are the WLM Franz S fully active speakers - they ar enot conventional in many other ways either. They employ two 8cm AMT tweeters, one in the baffle, one sitting on the top of the cabinet alike a supertweeter. In theory this is a recipe for many problems, my ears did not find anything annoying in how the Franz S sounded, except certain agility in the HF content.  Two paper woofers of the Race Track oval design (22 x 30cm) are invisible to eyes - one fires to the floor, the other to the ceiling. The driver complement  is completed by dual 12 cm midrange woofers with papyrus cones. The cabinet is a multilayered structure that also employs real wood. The stiffness is addressed through the variable thickness of the cabinet's walls - the material reaches up to 74mm thickness at the critical spots.

The WLM uses class D amplificiation inside, each band is fed by its dedicated amplification module. This facilitates the use of analog filtering. WLM does not believe in DSP and claim the analog filters are superior to it in the classical speaker design like Franz S. So, apart from the usual power socket, power switch, and two analogue inputs on RCA and XLR, there are 4 large knobs at the rear of the speaker. Those serve to adjust bass volume and focus, as well as to sculpt midrange and treble according your preferences.
