Dette er en kompleks høyttaler å beskrive. Den er både moderne og klassisk bÅde inn- og utvendig. Det meste av det du hører er et klassisk bredbåndselement. Legg til en god diskant og to basser som spiller i en lukket transmisjonslinjekonstruksjon, og det vil være vanskelig å forestille seg hvordan det kan høres ut. Svaret er at Stiletto må høres!

A Different Approach

The vast majority of available loudspeakers are of the ported variety, also known as tuned enclosure, “bass reflex”, etc. This type of design is based on the helmholtz resonator, in which a closed cavity is open to the outside by means of a tuned “pipe” or tube. The volume of the cavity, length and cross section of the pipe will create a resonance at a certain frequency (the resonant frequency).

Transducers radiate as much energy from the front of the moving membrane as from the back of the membrane. But the back energy is out of phase with the front energy and trends to cancel the sound output with acoustic short-circuit. This is why most loudspeakers (with the exception of open baffle designs) are mounted in a box.

Bass Reflex (or tuned) enclosures became very popular in recent years for two reasons:

First, the back energy that would otherwise be lost is reversed and added to the energy of the front of the membrane. The reversal process delays the energy by one cycle or more, but makes the design more sensitive, because the two waves are added together.

Second, the availability of computer program made calculations very simple and straightforward and predictable.

No Silver Bullet

One of the problems with Bass Reflex is the phase reversal process, which delays the vent output and blurs the definition of the sound wave. Another problem is Phase Delay — which is also caused by the phase reversal process, but depends on the design of the enclosure. Whether the listener objects or not to the delayed output is a matter of preference. In some situations (home cinema soundtracks for example), the delayed output is acceptable and perhaps desirable because it adds a sense of artificial scale to the sound.

A Novel Sealed Transmission Line Design

In critical music listening, phase and group delays should always be avoided. This is the reason why Stiletto is based on a novel folded sealed transmission line design, where the back radiated energy is transformed into heat and dissipated by the complex enclosure.

As seen in the cutaway illustration, the low frequency transducers (bottom two drivers) are mounted in a two-folds sub-enclosure. This sub-enclosure is entirely filled with Dacron fibers, which creates acoustic friction and transforms the energy into heat. The result is that only the energy coming form the front of the two transducers is kept. No phase reversal, no delays, just highly resolved low frequencies.

Ultra Damping

Another interesting aspect, unique to Stiletto, is the ultra damped, low Q design. The air volume in the folded line is large enough that the air trapped in the enclosure has no “spring effect” therefore, the amplifier entirely controls the movement of of the membranes, contributing to the extraordinary resolution of the systemm.

UnCompromised Phase And Coherency

Amplifier Coupled Quasi Full Range Low-Mid Unit

Stiletto is based on a quasi full range driver, reproducing almost 7 octaves of sound, with no delay or crossover related phase issues.

With a membrane of hand coated treated paper, this driver has incredibly good self damping characteristics, from 40 Hz to 4000 Hz, allowing a direct connection to the amplifier terminal with no Inductor or Capacitor in the signal path.

The result is incredibly smooth and pure sound. It can, by itself reproduce all of the vocal frequencies, and unlike other loudspeakers, vocals are not diced between 2 or 3 separate transducers.

How Do You Define “Fast” ?
Stiletto Is Designed To Be Ultra Responsive From The Highest Note (23 KHz), Down To The Lowest (27 Hz)

With its amplifier-coupled mid-woofer Stiletto has all the speed, impact and transparency you expect from a fullrange singledriver. But unlike a single driver, Stiletto’s output is complemented by two ultra-damped low frequency transducers for the ultra low frequencies and one silk domed high frequency transducer.
