ADM Stra To   Review   Lab Results

ADM Stra To Stra To (Strassacker Tower) was developed by Udo Wohlgemuth, with the briefing to design a jack-of-all-trades, be it a shelf or a floorstanding speaker, and that grows with the increasing demands of the user.

Udo Wohlgemuth's goal was to "again design a great speaker with marvellous tops and with an extremely three-dimensional and tight bass."

This floorstanding speaker (pictured left) consists of a subwoofer and a satellite on top of it. The satellite (pictured right) may be used on its on, together with a subwoofer or with a special subwoofer stand as floorstanding speaker.

Two small changements have been done: Instead of Detonation DT 80 we now employ two Mivoc AM 80. This one is able to drive 4 Ohm; therefor we deliver Alcone AC10 SW-4 instead of the 8 Ohm version.
