Interesting design, the rear mounted woofer - is that a passive or active unit? What is the potentiometer used for?

Setting the whole new level of quality takes time, perfection isn't easy to achieve, especially in respect to competitive designs nowadays present in high-end industry. The essence of what it will be offered to the customers in ready made product range will always be available in module form too, so anyone could get first hand impression in affordable way.

Module's measurement at 500 kHz square on 4 Ohm load attached.
The new FirstOne amp sounds best so far. Detailed and easy to listen to.

The rear unit is active. Measurement show that the speaker goes from 25Hz up.

The knob is not a potentiometer but will be a 3 position switch for adjusting treble to the room acoustics (similar like Tannoy or Focal).
