Leviton’s New Spec-Grade
Sound™ System
Setting a new price/performance benchmark in installed
home audio speakers, controls and distribution components
Leviton’s new Spec-Grade Sound system components take installed home audio to a new level in both
technical innovation and value, making high-grade audio performance a viable installation option for every
residential application.
Leviton carefully evaluated the leading-edge features and technologies that distinguish high-end speakers
(the ones preferred by top system integrators). Leviton then worked with one of the world’s largest OEM
master speaker builders (who makes many of the designer speaker brands) to craft a custom line of speakers
and related components that incorporate those same features and technologies for which the highest-rated
brands are famous. The result is performance that is identical, but at a price that works for
the contracting and residential construction business… designer sound without the designer price tag.
As a leader in residential and commercial networking systems, Leviton knows that any system is only as
strong as its weakest link. That’s why Leviton complemented its technical achievement in price/performance
for its speaker offerings with control and distribution components that, when combined with Leviton Spec-Grade Sound
speakers, result in a system limited only by the amplifier driving them and the quality of the sound source.
Spec-Grade Sound System Component Features
Spec-Grade Sound Indoor and Outdoor Speakers
1. Advanced phase/time alignment guide
While it’s important to hear accurate stereo imaging throughout a listening room, the moveable or swiveling tweeters used
by many in-wall speakers can actually cause more problems than they cure by deforming the speaker’s multi-frequency
polar response characteristics. Spec-Grade Sound uses a precise phase/time waveguide to properly align the sound
without misaligning the tweeter. It’s similar in concept to the alignment technology used in professional recording studio
monitors, where sonic accuracy is critical.
2. AeroNylon tweeter diaphragm
A tweeter and a parachute share a common need: incredibly high
tensile strength-to-mass ratio in order to perform. Spec-Grade
Sound uses aerospace-grade nylon to achieve a near-perfect
balance between extreme low mass and high tensile strength in
its tweeter which is diaphragm capable of moving tens of
thousands of times each second to faithfully track the most
challenging musical transients.
3. Kevlar®-composite woofer
A woofer must move in a perfectly linear isotonic fashion,
possibly thousands of time each second, in order to
reproduce critical low and middle frequencies. But to
start and stop almost instantly requires a woofer that is
exceptionally strong and rigid, yet very light. Kevlar fits the
first requirement – it’s literally bulletproof, which is why it’s
used for bulletproof body armor. The Spec-Grade Sound
woofer, with its layer of tough Kevlar on top of a light,
rigid organic substrate, is a high-tech compound solution.
The Kevlar-composite cone is harnessed to a precision
voice coil and magnet assembly and surrounded by
compliant, reduced-mass non-flame retardant rubber, to
form a powerful, high-performance electro-acoustic motor.
4. Precision dividing network
An equal partner in sound, the dividing network or
crossover makes the critical decision as to which
frequencies are assigned to individual drivers (tweeters
and woofers). Spec-Grade Sound specifies high-order
dividing network components and circuit design to
ensure total audio signal electronic integrity right up to the
last microsecond when that signal is converted into sound.
5. AutoSurge™ circuit protection
No one contractor, builder or homeowner – wants to deal with a dead speaker.
Spec-Grade Sound takes a cue from Leviton’s leadership in the field of industrial-strength
surge protection with AutoSurge protection built right into the speaker. Normally remaining in the background and out
of the audio signal (and completely inaudible as a result), the AutoSurge circuit activates only when a potentially
damaging power peak is present, saving the speaker from damage. It automatically resets after the event.
6. Inert mounting frame with dogleg installation points
With its powerful woofer comprising the heart of the speaker, the last thing the speaker frame itself should do is
move as any transmitted vibrations can impair in-wall or ceiling sound performance. Spec-Grade Sound relies on a
baffle-frame assembly incorporating high-density plastics to more effectively isolate the active speaker components
and a series of adjustable doglegs to rigidly clamp the speaker to the wall or ceiling material.
Kevlar is a registered trade make of E.I. du Pont de Nemours and Company.
Decora® Strauss™ Transformer-Free™ Volume Controls
Nearly all volume controls use audio transformers, called autoformers, to convert
the audio signal from one level to another. It’s a technology from the era of vacuum
tubes that has a built-in side effect with today’s ultra-wide-bandwidth digital sources.
Autoformers can filter low and high frequencies, which makes the volume control partly
responsible for the muffled sound often associated with installed speakers, especially at
lower listening levels.
To eliminate the problem, Spec-Grade Sound eliminated the autoformers and replaced
them with thermo-rated Cermetile resistors, made from the same high-tech compound
used in aerospace heat-resistant tiles. Because it presents the amplifier with a purely
resistive load at any volume level, the Decora Strauss Transformer-Free Volume
Control is ruler-flat across the entire audio spectrum (and well beyond it). Moreover,
because it can’t saturate like a conventional control, it can instantaneously handle the
full peak output power of any consumer-grade amplifier on the market today.
Spec-Grade Sound System Matching Module with AutoSurge Technology
One of the most challenging aspects of multi-room system design is matching speakers, zones and volume
controls to the amplifier. It either requires using less efficient impedance-matched volume controls (which must
be individually calculated and set) or an impedance-matching box added to the component stack.
Spec-Grade Sound takes a much more contractor-friendly approach: all system impedance matching is done
automatically by the Spec-Grade System Matching Module at the central wiring point where speakers and
controls combine to interface with the amplifier (either inside a structured cabling enclosure or at a designated
wallplate location).
The Spec-Grade Sound System Matching Module with
AutoSurge Technology is a solution that saves time and
money, as well as providing another point for a second
layer of AutoSurge circuit protection to ensure total system
reliability. The module is engineered for high power handling
and long-term reliability by being designed around the same
thermo-rated audio-grade resistors used in the Decora®
Strauss™ Transformer-Free™ Volume Control.
