The Invisa MPX MultiPolar™ In-Wall/In-Ceiling Loudspeaker combines the advantages of a direct-radiating loudspeaker with the enhanced spaciousness and dispersion of a bipolar speaker. This makes them the perfect choice for the rear or side surround channels of a multi-channel installation, as well as for front main speakers or for distributed audio multi-room installations. It can be easily mounted in walls or ceilings and is very flexible in terms of orientation. Like the other Invisa Series speakers, it has a flat magnetically attached micro-perf grille that covers the flange for an attractive, nearly invisible look. It combines two precisely angled spiderleg cast-basket 4.5" bass/midrange drivers, a High-Velocity Folded Ribbon Tweeter (HVFR™) and a complex precision crossover network with a high-frequency equalization switch. Like the Invisa HTR 7000, it features GoldenEar’s unique Non-Periodic Diffraction Control and Wave-Launch technology for enhanced clarity and source-less sound radiation into the room.
