Some of our clients says…
BEYOND THE SOUND
I don’t want to describe the system, it doesn’t matter, I’ve seen dozens of them. This is because when I listen to music, which is obviously not a concert, I close my eyes and therefore it makes no sense to judge from what I find in front of me. It’s the ears, the body that vibrates with every note, and the image that you create beyond your closed eyelids, that judge. And if in front of you you can see Robert Fripp while play to Starless, or Steve Hackett in Firth of Fifth, then it’s done. This is what I felt, these are my sensations, and then…then I opened my eyes.
A lion behind the robe of a gazelle...
A system with an unusual aesthetic and although very compact and discreet, the sight of a single speaker suggests a thin and limited sound, almost toy-like; and instead the solution has shown record-breaking performances even superior to many systems with a 5-figure price.
5 stars only because I can’t give 10!
Purchased to delight customers in our restaurant.

A sound stage never heard before with even much larger speakers
I was skeptical at first but I had to change my mind. It’s true, it brings musicians into your home: No other system in the world with similar performance in just 12 cm of width. Extraordinary.
Manager Four SPA Catania
Unbelievable
I couldn’t believe my eyes when I saw the demonstration: that speakers with a driver of only 7 centimeters sounded so loud and good! The music filled the room and the instruments were there all around us…

Beyond my expectations
I am a Jazz fan but I also listen to a lot of classical and 80s and 90s pop, I no longer notice how the hours pass when I am in my listening room with the new Key Silence system. Really satisfied beyond my expectations…”

Notes: (1÷4)
(1) The sensitivity value refers to 2.83V and not to 1W which in this specific case corresponds to 2W since the speaker has an impedance of 4 Ohm
(2) The total active surface is essentially the area responsible of sound emission and represents in a speaker, its ability to play at high volume and its ability to offer a wide soundstage.
(3) The drive factor is the ratio between the active surface that emits the sound and the weight of the moving surface (the speaker cone or their sum if there is more than one). It represents the ability or otherwise of the speaker to emit the sound without requiring excessive current from the amplifier.
(4) Finally, the mechanical stability ratio is the ratio between the weight of the speaker and the weight of the speaker membrane and represents the speaker’s ability to annihilate both internal and external spurious vibrations caused by the speakers during their operation.
These are parameters that are new to you and that you have certainly never encountered on the technical data sheets of other speakers, but which are particularly important for evaluating in advance what performance you can expect from the speaker in question.

Things You Might Want to Know
“What are the advantages of RHD technology?”
The RHD ® technology consists of a special horn-loaded dipole regulated by a mechanically controlled chord [Patented].
The solution allows to obtain the advantages of horn systems such as high efficiency and high acoustic power, but without the disadvantages such as high directionality and large dimensions..
Added to this is the ability of RHD® technology to return a musical message in an absolutely transparent and coherent way.
In fact, it does not modify the timbre in the various frequency regions as normally happens with multi-way systems.
The unmatched transparency of RHD® technology is also due to the total absence of non-linear components on the signal path (cross over networks).
Added to these advantages are those linked to an almost omni-directional emission which solves the problem of the focal point where the listener is normally forced to stay, under penalty of losing the stereophonic scene, as happens with traditional speakers.
Ultimately, high efficiency, very low distortion, an unparalleled soundstage combined with extremely compact dimensions are the main features of this innovative speaker system..
“What is the difference between the different power versions?”
The most important data that varies between versions is the SAT, total active surface: that is, the area that emits sound during operation.
As the size of the speaker increases, both the SAT and the efficiency and the acoustic power that the speaker can reach increase proportionally.
Given that even the smallest version can provide excellent sound even in rooms of over 100 m2, the larger versions obviously have a greater impact and the ability to reach high sound pressure levels..
“Why is the system considered a single-way system even though it has a tweeter?”
The symphony system is similar to a single-way system because the entire primary range of voices and the majority of acoustic instruments is entrusted to a single group of loudspeakers.
The reinforcement tweeter only intervenes above 12 KHz and a possible Sub Woofer below 100 Hz.
“Can I use the symphony speaker system on my existing system?”
The symphony speaker system has been designed and built in full compliance with the AODM protocol, with the aim of returning the musical signal sent to it with the maximum transparency technically possible.
Given this, it is natural to suggest the use of electronics of the same AODM level or at least high quality electronics..
Our suggestion is to consult our support before evaluating a possible purchase.
In this regard, you can obtain support and more detailed information by writing an email with this specific request to: assistenza@keysilence.com
“What is the ideal amplifier for the symphony system?”
The symphony speaker system features a dedicated solution that currently represents the best available on the market: we are talking about the TOWER TEN DM22 and DM22P solid-state Single End amplifier, currently the only amplifier in the world with SST® technology certified AODM class 0..
However, there are quality amplifiers from which you can get the best out of them by using them with the symphony speaker system.
And just to name a few, very good amplifiers include the PASS Lab class A, the SUGDEN Masterclass, the YAMAHA AS series…, as well as the single end tube amplifiers from the Italian company MasterSound.
“Which version should I choose?”
The symphony 8x series consists of 3 versions, all with extraordinary and in some ways out of the ordinary features..
Each of them has performances that only speakers 3 to 5 times larger (maybe) could have..
If you have a room of at least 30 square meters, the intermediate version may be the best choice..
The largest of the family is certainly recommended for rooms larger than or equal to 80 m2, where they can best express their extraordinary qualities to recreate a LIVE effect.
In smaller environments, the first of the series will be able to provide the greatest listening satisfaction.
However, consider that even the smallest of the series is able to conveniently provide sound in environments of up to 80/100 m2 and that in cases of listening dedicated to classical music, given the typical listening volumes, it can already be the optimal solution..
“Why buy a Loudspeaker symphony system?”
Come per il TOWER TEN, il sistema diffusore symphony è un prodotto artigianale esclusivo, che si accompagna ad una garanzia reale di 5 anni estensibile a 10.
It is a furnishing accessory, an object made to last over time and to be handed down like a family jewel..
It is therefore a demanding product, not for everyone.
