ACE Loudspeaker System: The ACE Series Loudspeakers are professional full-range two-way compact loudspeakers designed for the most demanding concert sound and live performance requirements. The ACE Series Loudspeakers feature passive two-way crossovers with a high-frequency driver protection circuit. The protection circuitry allows ACE Loudspeakers to handle occasional power spikes that would destroy most other speaker systems. The compression drivers in the ACE Series Loudspeakers have titanium diaphragms and annular phase plugs for superior frequency response. The woofers are designed for maximum efficiency and robust power handling. The well-damped speaker enclosures are made from an advanced polymer using an injection molding process. With up to two built-in handles and cast aluminum pole mounts -- ACE Loudspeakers are perfect for bands and DJs on the go. ACE Loudspeakers are designed to form the basis of anything from a P.A. system for a band to a full-size concert sound tour system. They can be used as a single unit in pairs or as part of a larger loudspeaker array. These speakers are ideal for use as a two-way system or as the mid / high pack in a three-way set-up incorporating a subwoofer loudspeaker system. The ACE loudspeaker systems are designed for easy repair in the field with front removable compression drivers and woofers unlike the competition where the cabinet has to be disassembled in order to make any repairs.
