ADM Stra To   Review   Lab Results

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.

Impedance correction for valve amps
If you want to drive the Stra To with a valve amp, then you need an impedance correction. The required components for the standard and high-end version of the satellite are listed on the right.	0.7 mm IT air core coil 0.47 mH/0.57 Ohm ELCO, non-etched 22uF / 50Volt MOX4 10 Ohm/4 Watt (brown-black-black) the building instruction
