"Alamidle- kuntoon"- kajari(Sitä on kivasti paljon) "Tanan iso ja hifi NS-10". "Ihanan kolmiuloitteista" "Mahtavat midletransientit" "kiva kun on hiukka pehmeämpi tuo nauhadiskantti" ja niin edespäin voisivat olla heittoja siitä S3-A:sta.
 
Mielenkiintoisia luonnehdintoja ottaen huomioon että särön määrä Adamin ART "nauhadiskantissa" on ihan järjetön.
 
Sound on Soundista pastettua: "The Accelerated Ribbon Technology (ART) used in all the ADAM speakers for the tweeters (and also the mid-range units in the larger three- and four-way systems), while still a ribbon design at heart, is fundamentally different in its operating principle and is claimed to overcome all the limitations of previous ribbon designs. The ART tweeter is based upon ground-breaking research by Dr Oskar Heil, dating back to the early '70s, which resulted in a sound driver he called the Air Motion Transformer, and ADAM has refined and 'productionised' this concept to produce the ART tweeter and mid-range units employed in all their monitor designs.
 
While a ribbon tweeter driver is usually constructed from a small piece of metal foil, the ART diaphragm is constructed from a type of plastic, with a metal coating to make it conductive — this helps make the construction more robust. The coated plastic is folded like a concertina and placed between the poles of a very strong magnet. It is engineered in such a way that when a current is passed through the ribbon the individual folds move to squeeze or pump the air in and out, instead of simply pushing the air like a piston, which is what virtually every other loudspeaker design tries to do, whether by using cones, domes, or flat panels.
 
The impedance of this ART ribbon is a comfortable 3.2(omega) over the entire frequency band, making it a fairly straightforward load to drive, and the design can handle two or three times the thermal power of a conventional one-inch dome tweeter, which enables it to be used confidently in high-powered professional monitor loudspeakers. With conventional loudspeaker technology, the diaphragm acts on the surrounding air like a simple piston, moving air in a straightforward 1:1 velocity ratio. In other words, the speed of the diaphragm movement is the same as that of the air it displaces. This is not terribly efficient given that the mass of the diaphragm is many times more than that of the air it is moving.
 
The pumping action of the ART design is far more efficient and achieves a 4:1 velocity ratio (3.5:1 for the mid-range version), meaning that it moves the air four times faster than the movement of the folds in the ribbon itself. The advantage is much better impedance matching between the mass of the diaphragm and that of the moving air, resulting in greater transient accuracy than more familiar transducers. It also makes the driver very efficient — typically around 93dB/W/m. Furthermore, the folded nature of the diaphragm neatly side-steps the problem of breakup which afflicts cones and domes at the upper frequencies of their bandwidths. As the wavelength of sound becomes small relative to the size of the diaphragm, cones and domes tend to lose their stiffness and no longer act like perfect pistons, limiting their dynamic ability.
 
Another interesting aspect of the ART design is that, because the diaphragm is three-dimensional (thanks to its folds), the actual surface area is around 25 times larger than the baffle space it occupies. The ART tweeter has a total diaphragm area of around 71 square centimetres, for example, and the mid-range unit has a total diaphragm area of 213 square centimetres. This means that for the same physical excursion as a conventional driver the ART design moves substantially more air, and can therefore produce higher SPLs. In terms of its useful bandwidth, the ART tweeter can be used to handle frequencies above about 1.8kHz, extending to around 35kHz. The mid-range ART unit is typically used between about 600Hz and 3kHz."
 
Eli hyötyjä on mm. impedanssin ja tehokkuuden muodossa mutta särön määrä "vanhaan" ribboniin verrattuna on holtiton.
