Please Read Before Purchasing

Because the package combines HELIX speakers with sophisticated multi-channel DSP amplification, professional calibration is strongly recommended. Correct setup is important for crossover configuration, equalisation, time alignment, channel levels, phase and subwoofer integration.

Installation and DSP tuning fees are not included in the online product price.
