HECO´s Celan GT 702 is the middle of three floor standing speakers in the series and features enough space for a double-bass configuration with two 170 mm woofer chassis. Perfectly coordinated individual chassis with an outstanding level of precision and a completely redefined dynamic response ensure unlimited listening pleasure. At the heart of the sound in this series lies the new tweeter. This 30 mm high-energy tweeter is significantly larger than conventional tweeters and features a special cone geometry that differs from other tweeters by its oversized edge mount. This creates a considerably higher dispersion energy in the transition to the midrange than is possible with conventional designs. One feature both the woofer and midrange driver have in common is a sturdy die-cast aluminum basket with linearised magnet system. An elaborately constructed, sturdy MDF housing forms the workspace for the chassis.
