Overview: The Definitive Technology Mythos STS SuperTower is
a tower loudspeaker with a built-in powered subwoofer. The Mythos STS SuperTower
design offers a truly full-range loudspeaker that combines the accuracy,
imaging, and detail retrieval of a monitor speaker with the depth, dynamics, and
bass output a separate powered subwoofer into one visually attractive,
small-footprint enclosure. The Definitive Technology Mythos STS SuperTower
utilizes a 1-inch pure aluminum dome for extended highs and two 4.5"
high-definition cast-magnesium basket midranges for smooth sounding vocals. The
Mythos STS SuperTower also features a "racetrack" shaped carbon fiber active
driver powered by a built-in 300-watt Class-D amplifier and pressure-coupled to
two "racetrack" shaped low-bass radiators equal to the surface area and bass
output of a 12-inch woofer but with far greater control, definition and speed;
eliminating the need for a separate subwoofer. The STS SuperTower features a
and-polished gloss aircraft-grade extruded aluminum enclosure with proprietary
damping technologies and polished granite base to ensure total rigidity and
stability. The Mythos STS SuperTower has been engineered for music listening and
home theater enjoyment.

Driver Technology
BDSS Technology: Definitive Technology's Balanced Double
Surround System (BDSS) driver offers a wide-bandwidth accurate frequency
response, broad dispersion, low distortion, and detail retrieval; so you hear
more the music with greater accuracy and enjoyment. BDSS drivers incorporate the
following design features.
- Balanced Double Surrounds: The speaker's balanced
double surrounds support the cone at two points to provide better mechanical
stability for longer, more linear excursion, and improved damping to
suppress parasitic cone resonance.
- Mineral-Filled Polymer Cone: The loudspeaker features a
deeply drawn mineral-filled polymer cone engineered using sophisticated 3D
modeling techniques for wide range performance.
- Waveguide: The cone's integrated waveguide smoothes
off-axis response for broad, even dispersion and better imaging.
- High Temperature Voice Coil: The driver's high
temperature, oversized, lightweight vented voice coil offers improved power
handling and quick transient response. The voice coil is also lengthened to
increase linearity and lower distortion.
- Magnet Structure: The driver's magnetic system is
optimized by finite element analysis to maximize magnetic flux in the gap
for high efficiency and linear excursion.
- Die-Cast Alloy Basket: The die-cast alloy basket
minimizes ringing and vibration while the open area minimizes back wave
reflection.
High Definition Midranges: The Mythos STS SuperTower
contains a D'Appolito array consisting of two high-definition 4-1/2 inch drivers
surrounding a 1-inch 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.
Pure Aluminum Dome Tweeter: The
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, smooth
highs.
Magnetically Shielded: The Mythos STS SuperTower is magnetically
shielded for safe placement near your television.
Break-In Period: The Mythos STS SuperTower will sound good
right out of the box; however, an extended break-in period of 40-60 hours or
more of playing is required to reach full performance capability. The break-in
period allows the suspensions to work in and results in full bass, a more open
midrange, and smoother high frequency reproduction.
Built-in Powered Sub
Powered Subwoofer: The 5 x 10-inch "racetrack-shaped"
polymer/carbon composite subwoofer is powered by a built-in 300-watt Class D
amplifier and pressure-coupled to two 5 x 10-inch "racetrack-shaped" planar
low-bass radiators for a total bass radiating area greater than a 12-inch
woofer; but with far greater control, definition, and speed. A pair of STS tower
loudspeakers is like having two 12", 300-watt powered subwoofers in your room
without taking up anymore floor space. The result is bass that is deep, powerful
and impactful while at the same time having tight, controlled, and accurate
response. The built-in powered subwoofer also provides the following features.
- Auto Turn-On: The Mythos STS's built-in active power
subwoofer section must be plugged into an electrical socket using the
supplied 10' AC cord. The Mythos STS has a special circuit which
automatically turns the powered subwoofer section on when a signal is fed to
the loudspeaker and turns off when there is a no signal (for 1-hour).
- LED: An LED on the back-panel will light up when a
signal is sensed and the amplifier turns on. The LED will automatically
turn-off when there is no signal (for 1-hour).
- Built-In Crossover: Definitive's engineers have
perfectly adjusted the crossover and phase between the subwoofer and main
speaker sections of the Mythos STS SuperTower to achieve seamless blending
and life-like sound.
- Note: Please not that there are no controls to vary
the crossover points or phase because these have been factory calibrated
and set to provide perfect blending.
- Level Control: The Mythos STS SuperTower has a
bass-level control which allows you to tune the output level of the built-in
powered subwoofer section to match your room and personal listening
preferences.
- Protection Circuit: To prevent accidental damage to the
subwoofer built-in the Mythos STS SuperTower from overdriving the system,
the built-in powered subwoofer section features an internal overload
protection circuit, which will turn the powered subwoofer off or down when
overdriven or overheated and will then resume normal operation after a few
minutes.
Enclosure Design
Curved Extruded Aluminum Enclosure: 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. The slim,
curved shape of the enclosure reduces diffraction contributing to the ST's
broad imaging and deep soundstage.
Connections
Speaker-Level & Line-Level Connections: The Mythos STS SuperTower is equipped with a pair of
gold-plated, 5-way binding posts to attach your receiver's speaker wire and a
gold-plated, mono-RCA/LFE input to connect your receiver's LFE/subwoofer output.
Mounting Options
Granite Base with Adjustable Feet: The
granite base combined with the heavy Toroidal transformer mounted on the bottom
plate of the loudspeaker's 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 and ceramic
floors, or spikes for carpeted floors.
Applications: The precise accuracy, wide-range response, and high impact dynamic range of the
Mythos ST allow you to use the speaker in most home audio/video system's
ranging from a 2-channel music-only to a 7.1 channel home theater system.
When used as a stereo pair, simply connect it with speaker wire as one would any pair of speakers; there is
no benefit to using the low-level LFE inputs. When using the ST in a
multi-channel system there are two options.
- Connect speaker wire as in a stereo system; set bass management as Front=Large, Subwoofer=None
- In addition to speaker wires connect low-level cables from the LFE/Subwoofer output of the
receiver/processor to the LFE inputs of the ST (Y connector is usually
required). Set bass management as Front=Large, Subwoofer=Yes. The benefit of
this hook up method is that one now has the ability to control the level of
the LFE channel relative to Front L&R bass.
Placement: The Mythos STS SuperTower loudspeaker can be used as a Main
or Surround speaker.
- Fronts: When used as a front main speaker, you should create an
equilateral triangle between the speakers and your listening area. The
speakers should be angled toward the center of the listening position for
brighter, clear, sound with a sharper focus and a more solid central image.
Pointing the speakers straight forward, parallel with each other , will
result in a warmer less sharply focused sound. To get the best possible
imaging and most even tonal response, avoid placing the speakers less than
3-feet (1-Meter) from your room's walls.
- Surrounds: When used as rear or surround speaker, the Mythos ST may be
located on the side or behind the listeners. When used on the sides, take
care never to locate the speakers forward of the listeners. When the
side/rear speakers are close to the listening position, do no aim the
speakers directly at the listeners.
