The ALTEA-718A is a powered subwoofer system designed to provide extended bass response for the ALTEA full-range cabinets. At the heart of the system is a DAS 18FW4 bass loudspeaker. This loudspeaker incorporates a FEM optimized high-efficiency speaker design and an extended 3″ voice coil for long excursion. Cooling is assured thanks to the 18FW4´s vented pole piece and abundant apertures in the speaker´s back plate keeping power compression to a minimum while providing high acoustic output over extended periods.
Driving the DAS 18FW4 loudspeaker is a cutting-edge 1200 Wpeak Class D amplifier. On the rear panel a balanced input connector and stereo “loop thru” output connections are available to provide signal for ALTEA satellite systems. Thanks to the digital presets accessible by way of a DAScontrol™ interface on the rear of the cabinet, setting up a combo system with ALTEA full-range systems is easy.
The ALTEA-718 is the passive version for use with external amplification and outboard DSP.
