OWINGS MILLS, MD. — Definitive Technology plans to introduce three more super-thin speakers later this year to join the 1.5-inch-deep Mythos XTR- 50, a $699 two-way LCR designed to complement ever-thinner LED-backlit LCD TVs, said Paul DiComo, and product development senior VP.
The 27-inch by 6-inch by 1.5-inch XTR-50, sized for use with 46- to 55-inch fl at-panel TVs, can be mounted horizontally or vertically on walls or stands. It’s positioned as the market’s thinnest component speaker that be placed up against a wall.
The additional models will be positioned above and below the current model in price point and length, but like the XTR-50, they will be only 1.5-inches- deep at their maximum depth at the center of their enclosures, which get thinner toward their edges.
Definitive will introduce the new models at the CEDIA Expo in September and ship them later in the year.
Strongly rising sales of LED-backlit LCD TVs are creating new opportunities to improve TV sound quality, especially when the TV speakers fire downward, DiComo explained.
A number of Definitive dealers have already begun demonstrating the XTR-50 speakers with TVs, and DiComo said he expects dealers who do so will enjoy greater volume than if they display the speaker with other speakers in their stores.
Definitive thinned out the XTR-50 without thinning out the sound by using dynamic drivers, which use a voice coil sitting in a magnetic field, instead of turning to flat-panel drivers, which DiComo said don’t perform as well. Definitive also avoided electrostatic and ribbon technology for multiple reasons, including expense and a bipolar-radiation pattern that prevents them from being placed up against a wall, DiComo said.
To get dynamic drivers into a 1.5-inchdeep chassis, Defi nitive turned to dome drivers instead of traditional cone drivers, enabling the company to place the voice coil inside the dome to reduce depth, Di- Como said. Another strategy was using small-but-strong neodymium magnets and allowing the magnets to protrude through the enclosure’s back panel while remaining flush with the back of the enclosure. A gasket around the magnet prevents air leakage and conducts heat to the aluminum back panel, turning the back panel into a heat sink.
