A thing that decided about the great sound quality of the APS-715SUB is the Powersoft D-Cell series amplifier - and, as it's well known, the Italian manufacturer excels in that department. The integrated DSP responsible for the frequency division maximised system capabilities and versatility. Powersoft stands out in these matters, surpassing other manufacturers on the market.
A big impact on the professional sound quality has the loudspeaker itself. The transducer made by other world class producer from Italy - FaitalPRO provides low Qts parameter, thus enabled to reduce the size of the enclosure while maintaining the sound parameters characteristic for units with larger capacity.
The cabinet is constructed from plywood for enhanced sonic properties and finished with the polyurea coating for long-term use. Special cuts enable stable stacking (placing columns on top of each other).
All these components make up the subwoofer with optimal dimensions and weight. The variant with the neodymium type loudspeaker weights only 24 kg, making it one of the lightest constructions of that type in the world.
The quality of the subwoofer will be especially appreciated by those who have had great problems with setting their speakers in acoustic severe rooms.
