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.
