It may deliver taut gut-churning bass all the way down to a seismic 18Hz, but the Gold W15 is also an intelligent design, featuring an advanced automatic room correction system called LEO™ (Listening Environment Optimizer). LEO simply and automatically eliminates the detrimental bass boost of boundaries and corners through the use of a microphone and test tones. The Gold W15's sealed enclosure and front-firing driver make it easy to install, and calibration from the front-mounted controls and dimmable LED display is simple, even from a distant position. It's equipped with a 12V trigger and remote control with four user EQ pre-sets.
