30.09.2015 / Back to full range 

The various tests done with and without an additional tweeter filtered through a 12 then an 18 dB/octave high pass passive crossover have pointed out the complexity of making the tweeter work in a fluent way with the full range driver. Some mods were implemented to the listening system i.e. a Toshiba CD player used as a drive (Philips transport) coupled to a DIP Audio Monarchy resynchronizing electronics, a Totaldac d1-single D/A converter and N.O.S Yamamura Churchill loudspeaker cables. The definition and the high frequencies extension of the EMS LB12 full range driver have positively improved. So the tweeter upgrade will remain on the shelves until… To be continued…

20.11.2013 / Haute Fidelite 2013 audio show in Paris

The Haute Fidelite Paris audio show held on last november 9 and 10 at the Marriott Paris Rive Gauche hotel. Madotec formed a partnership with Ming Da Europe for exhibiting and demonstrating the Enceinte Bleue for the first time in public.


The demo system included Metronome Technologie T5 transport and C5 converter (lent by Point Musiques) set on a MinusK isolator table (lent by RoboliDesign).  All cables were Absolue Creations Tim Reference. The electronic part was Ming Da business with a MC-2A3 PRE preamplifier and as a world premiere one pair of the brand new 212 push-pull monoblocks feeding the Enceinte Bleue. The loudspeakers were fitted with LB12 special edition.

The cone receives an ultra thin palladium film with ground lead for static draining. Moreover the painted and varnished wooden phase plug used on Saturday was replaced by a massive aluminium one available as an option with field coil drivers. It helps keeping field coil temperature low.

The listening sessions attracted a lot of visitors notably in the afternoon when the electronics got at their working best. The « live » tracks gave the stunning impression of being there thanks to a spectacular imaging.
