The Future Has Arrived!

The Definitive Mythos XTR-60 is the step-up larger version of the original XTR speaker, the highly acclaimed XTR-50. The XTR family speakers are the first high performance on-wall speakers whose depth matches that of today's ultra-thin TVs at a mere 1.5 inches deep, shallower than many ultra-thin TVs when they are wall-mounted with their factory sanctioned mounting hardware. Beyond its utility and clean modern styling the XTR-60 stands out due to its uncompromising sound quality equivalent to full-size speakers. Definitive's engineers have unleashed their awesome creativity and brain power to develop this revolutionary line of speakers that have the high definition detail and dynamic range performance of large speakers yet are a mere 1.5" deep. No other speakers complement your ultra-slim television with more style, versatility and sheer performance.

The Thinner the TV, the Worse the Sound
Ultra-shallow TVs are the hottest category in TVs today. People love their space-saving qualities and elegant design. But it comes at a high cost-significantly poorer sound quality. The speakers in these ultra-thin TVs are small and poorly placed (usually on the bottom or on the back of the set) not even facing the listener. The result is sound that is good enough for news broadcasts but far from what is acceptable for sports, movies and action/adventure programming. Imagine the letdown when you return home after seeing Avatar or similar audio/visual blockbuster in a Dolby Digital cinema and turn on your TV to watch a DVD with cheap 2-inch speakers providing the sound!

In order to equal the total high impact sight and sound experience that high definition digital sources are capable of delivering, a great TV deserves a great component audio system. And the only component loudspeakers that can deliver clarity, dynamic impact and life-like realism whilst matching the slim styling of new generation TVs are the Definitive XTR series.

Revolutionary XTDD Technology Drivers
The secret to the XTR-60's extraordinary performance is Definitive's patented XTDD technology anodised Aluminium dome driver. Using province-of-the-art computer modeling and decades of speaker design experience, Definitive engineers eliminated every bit of wasted space, optimized every part and maximized the moving surface area of a dynamic driver to shrink it down to an impossibly compact dimension without giving up ultra high performance audio fidelity! The XTDD driver has the kind of dynamic punch, wide frequency range and broad dispersion that flat vibrating membrane panel-type speakers simply cannot match.

To extend and deepen the bass response of such an impossibly thin speaker four active XTDD drivers are pressure coupled to four anodised Aluminium dome bass radiators. The centre-mounted tweeter is the same hyper-definition Pure Aluminium Dome Tweeter found in Definitive's award-winning province-of-the-art Mythos ST SuperTower®. The total effect is the kind of clarity, dynamic range and extended response that one would expect from a premium-priced normally-sized speaker. Your friends and family will be agog with amazement when they hear the huge rich sound that comes out of the wafer-thin XTRs.

Aircraft-Grade Aluminium Enclosure Saves Space and Improves Performance
Another secret to the XTR-60's astounding thin profile and superior performance is its aluminium cabinet. By specially shaping the enclosure and incorporating stiffing ribs and channels, we've made the space-efficient aluminium extrusion ultra-rigid and resonance-free. The magnets of the XTDD drivers protrude through the rear wall of the enclosure to further minimise depth. A thermally conductive gasket seals the enclosure/magnet interface and transfers heat from the driver's rare-earth magnet to the enclosure, making the whole enclosure a giant heat dissipater! And everyone knows that a cool driver is a happy, reliable driver.

Is It Thin Enough?
With TV manufacturers advertising TVs with 1.25 inch and even less than 1-inch depth one might wonder if the XTR-60 is shallow enough to look good next to these impossibly thin TVs. The answer is a resounding YES. First, the advertised depth of a TV is the depth without the hardware necessary to mount the TV on a wall. For examplethe leading brand of LED TVs is advertised as being 1.2 inches deep. But the wall mount hardware brings the installed depth to 1.75-inches, .25-inches deeper than the XTR-60 installed on-wall. Should TVs get even thinner the XTR-60's design is up to the challenge. The XTR-60 is bow shaped with knife-edge sides. The sides are less than an inch from the wall so even if TVs get shallower; the XTR-60 will be up to the task.

Ultimate Placement Versatility
The XTR-60 comes supplied with everything you need to use place it wherever you want to use it. The XTR-60 can be mounted directly to the wall using the key-hole slots on the back of the enclosure and well-anchored screws. If you choose, the speaker can be wall mounted using the supplied mounting bracket that allows either vertical or horizontal orientation with a total installed on-wall depth of only 40mm. Two adjustable support feet are supplied in cases where you place the XTR-60 on a shelf as a centre channel speaker (horizontal orientation). For vertical shelf or table top placement the XTR-60 comes with a beautiful tempered smoked glass base. Whether you're mounting it on wall or on shelf, as Left and Right, Centre or Surround channel speakers the Mythos XTR®-60 is ready to look terrific and sound astounding.
