Partially active with 2-way crossover for the high-midrange section and amplifier for the bass.
Fully active (without passive crossover, no separate power amplifier needed)
Active with amplifier, which controls the tweeter and midrange driver via a passive 2-way crossover and directly the woofer (no separate power amplifier required)
As a passive 2-way loudspeaker without the bass woofer
As an active 2-way loudspeaker without the bass woofer

The kit is delivered with the following drivers:
- a Audaphon APR 1.0 ribbon-tweeter
- two Wavecor WF182CU13 woofers

The loudspeaker has been developed by Dennis Frank and Daniel Gattig.

The frequency response of this speaker is perfectly linear.

The decay spectrum as shown in the waterfall diagram is exemplary, free of any disturbing resonance.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,3% above 500 Hz and doesn't exceed 0,5% at 95 dB at 1 m between 500 and 20000 Hz.
