Reviews from around the world have raved about the Helicon 400 and it has received numerous awards. The H400 is the ideal solution, combining good looks with high end sound.
Basically, the H400 is a 2½ way bass reflex speaker with 2 x 6.5" bass/midrange woofers and the proprietary DALI ribbon/soft dome hybrid tweeter module. However, as the dome and the ribbon do not cover the same frequency range, one could call it a 2½ plus ½ way. The advantage is accurate sound with high frequencies suitable for SACD and DVD-Audio recordings.
As in all Helicon models, the 400 features a luxurious high gloss laquer real wood finish, curved sides and real wood front baffe as well as paper/wood fibre cones and the Hybrid Tweeter Module.
The Helicon Series is developed, designed, hand-built, assembled and individually tested at the DALI factory in Denmark.
