Ultrumax-U2-ST Speakers



  Ultrumax-U2a-ST Speaker

             The -U2a-ST is the premium version of the Ultrumax-U2a speaker; both the basic design and characteristics are similar except M&D’s famous Omni-Harmonizer feature has been integrated onto the top of this bit larger enclosure over the Ultrumax-U2a speaker.

            It is the common characteristic for tweeter drivers that their emitting directivity will be sharper/narrower when playback for higher frequencies; people may feel the music some unnatural during audition. Add on this AMT super tweeter + cone diffusor with omni-directional (360 degree) scattering; and it is purposely designed to respond only to musical High Frequency harmonics, from 7KHz up to 32KHz, the very high frequency band so it will not affect the positioning when music playback but be able to obtain a more vivid spatiality with the High Frequency harmonics by producing a certain proportion of indirectly HF reflections to the listener. This thereby achieves better acoustic spatiality in the very high frequency band and gains a lifelike ambiance.

* Note: Proper Installation for the Cone Diffusor:

-Pick up the CAM diffusor then use a hexagonal wrench to slightly loosen the 4 screws on its top ① so the 4 stainless steel posts may be relax a bit ②

-Insert diffuser’s 4 posts properly into the 4-hole position on the Harmonizer’s top ③

-Firmly press the diffusor with one hand, then properly lock the 4 screws on its top plate with the hexagon wrench ④
