coaxial and triaxial loudspeakers are based on the visual concept
of the QUANTUM QE systems and convince with almost the same
sound characteristics. The four models are available in standard
Euro-baskets and represent the optimal solution for front and
rear staging in space limited environments. Low vibration steel
baskets, high temperature 1“ (25 mm) Kapton carried voice
coils, poly-injection cones with aluminum look and elastic Butyl
surrounds guarantee high load capacity and best midrange performance.
The silkdome tweeters assure precisely defined heights with
very good dispersion. The QE speakers emphasize the high aims
of the ESX engineers, to unify modern design with perfect sound
- and this with moderate installation efforts and a best price
performance ratio. The four models of the QE SERIES are equipped
with the costly tooled speaker grille frame set, which can be
mounted without the mesh grille.
