All about Impact 400

Features
Most of us would agree that subwoofers are definitely needed for emotionally and physically engaging home theatre experience.
Yet many claim that subwoofers are not a correct solution for 2-channel music systems as despite improved bass extension the compromises in the midrange are too big to live up with.
Impact subwoofers might for you if:
-
You are hesitant about having a subwoofer in your music system
-
You are looking for a home theater sub with finesse
-
If nuances, tonality, speed and creating acoustic spaces are your thing rather than pure boom and bang.
Impact 400 provides easy placement and sufficient pressure levels to most rooms from its 10" driver. Powerfull 500 W module provides surprisingly speed and tonality.
CSC-technology
(Cumulative Stage Coupling)
All Amphion subwoofers incorporate Amphion´s proprietary CSC-technology, which increases the coherence of the whole system greatly and keeps the phase correct at all times by altering the filtering slope.
When the crossover point is set higher the filtering slope steepens gradually when moving towards higher frequencies. Thus the phase changes are linear and the group delay stays minimal.
At the rejectionband (>150 Hz), the slope steepness is 30dB/octave (5th degree) which keeps subwoofer inaudible and thus improves stereo imaging and selectivity.
CSC ensures that subwoofer and main speakers work seamlessly together in all situations. CSC filter can be by-passed by x-over/direct- switch so that Impact can be also connected to the LFE channel of the home theater amplifier.
