of the HDX series impress by an excellent power capability of 2,000 WMAX. Even at maximum load, they ensure operating reliability. These speakers provide a sophisticated ventilation of the drive system. High mechanical reserves are possible due to a very high excursion of the extra rigid cone, double centering spiders, special multi-roll surrounds and heat-resistant voice coils.
