Product Information

The Mythos STS SuperTower combines stunningly beautiful designs and precision fit & finish with jaw-dropping ultra high-end performance. No loudspeaker before them has achieved the balance of beauty and brawn at anywhere near their price. The Mythos STS's magic starts with a sleek and sexy polished black cabinet mounted on a beautiful polished granite base and continue with our most advanced components and technologies. Topping off the ground-breaking design is the incorporation of SuperCubeTM powered subwoofers right into the enclosures. With two built-in 300 Watt powered subwoofers you'll enjoy double the bass while saving floor space and enhancing the beauty of your room.

The Case for Integrated SubwoofersBesides eliminating the need for a floor space hogging separate subwoofer, integrated subs offer dramatic performance benefits. First is the obvious benefit that you'll have two subwoofers in the room instead of just one for simply more bass output. Most importantly the subwoofers are perfectly integrated with the mid/high section. Audiophiles often spend dozens of hours moving and adjusting their subwoofers' crossover and phasing controls in pursuit of perfect subwoofer to main speaker "blending." With the Mythos STS you won't have to go through that kind of hassle to get audio perfection. Definitive's engineers have perfectly adjusted the crossover and phase between the subwoofer and main speaker sections to achieve seamless blending and life-like sound. All you have to do is set the bass volume to match your room and taste then sit back and enjoy audio perfection.

Rock-Solid Beautiful Enclosure

The slim, curved shape of the enclosure reduces diffraction contributing to the STS's remarkable imaging that is truly startling in its ability to float utterly lifelike sonic images across a broad and deep soundstage. The granite base combined with the heavy Toroidal transformer mounted on the bottom plate of the enclosure provides a low center of gravity for superior stability. The base incorporates 5 adjustable-height metal feet that may be fitted with either smooth furniture glide tips for wood or ceramic floors or spikes for carpeted floors.

The enclosure is extruded Aluminum with internal ribs for stiffening purposes. Strips of damping material are adhered to the inside of the extrusion to suppress ringing. The baffle is "Polystone" a dense and non-resonant mineral-filled Polymer material that is slightly oversized and is force-fit into the extrusion "mouth" to prevent the Aluminum from ringing. The midrange/tweeter array is isolated from the woofer enclosure by two pieces of MDF. Both woofer and mid/hi enclosures are sealed.

Midrange DriversEach Mythos STS contains a D'Appolito array consisting of two high-definition 4-1/2 inch drivers surrounding a 1inch dome tweeter housed in an acoustically isolated sealed enclosure. The drivers feature Definitive's patent-pending Balanced Dual Surround System (BDSS) technology that supports the speaker cone at both the inner and outer edges for longer, more linear excursion, greater clarity and finely textured inner detail. The driver baskets are die cast Aluminum.

TweeterThe tweeter is a pure aluminum dome, which has been heat-treated to relax the crystal structure and then coated with a ceramic to produce extended highs that reveal nuance and shimmer without a trace of edginess.

Subwoofer SystemThe subwoofer is built around a 5 x 10 inch racetrack-shaped polymer/carbon composite cone driver powered by a built-in 300-Watt Class D amplifier and pressure-coupled to two 5" x 10" racetrack-shaped planar low-bass radiators for a total bass radiating area greater than a 12" woofer but with far greater control, definition and speed than a single sluggish large woofer. The result is bass that is deep, powerful and impactful while at the same time having the kind of tight, controlled and accurate response of the finest and costliest audiophile speakers.

The Sound Will Amaze YouWe could write adjectives all day long in an attempt to describe just how good the Mythos STS sounds and we would fall far short of capturing the experience. If you are a true music lover, you need to hear them for yourself to discover just how lifelike a pair of speakers can sound. You'll hear depth and nuance to your music you have never heard before (unless you own a pair of speakers several times the cost of the STS). You will marvel at the dynamic impact and sheer bass power when watching movies, amazed that all that power is coming from just two small towers without a separate subwoofer. Yes, you will be astonished.
