paja959 Posted November 21, 2014 Report Share Posted November 21, 2014 www.6moons.com/audioreviews2/soltanus/1.html Loudspeakerlandia can be divided into two major continents. On one thrives the dynamic driver, on the other hides the planar transducer. The dynamic driver is most populous by far. Due to its vast dynamic range, high power handling and sensitivity plus quite simple design and concomitantly lower manufacturing costs, almost 99% of all loudspeakers use cones ‘n’ domes. Flaws in a driver’s frequency response are relatively easily compensated for by limiting its bandwidth and commissioning other drivers designed specifically for a certain range; woofers, midranges and tweeters. Together with a filter system called the crossover, an array of drivers packed into a loudspeaker acts as one and in many cases it will still be considered a quasi point source. Next to acting thus, dynamic drivers all share another feature - a voice coil. Electric current from the amplifier is sent through it. Being suspended inside a magnetic field created by two permanent magnets whose lines of flux cross the gap between them, the voice coil floats in said gap. Physics dictate that the current flow through the circular coil in the flux field causes magnetic forces to operate along the coil’s axis: the coil moves forward and back. Attached to the coil—in fact to the so-called former on which the coil is wound—is a cone or dome generally called a diaphragm. The faster the current alters in the coil, the faster the diaphragm will move the air it pushes against and the higher the frequency of the air movements will be. Those air movements are detected by our ear-brain system to translate as sound. Some sounds are even discerned as, yes music by our cognitive mechanism. By contrast, planar loudspeakers do not use coils floating in a magnetic field. In a ribbon loudspeaker, a strip of aluminium is suspended between two strong permanent magnets. The music as current is sent though the ribbon which creates a magnetic field around it. This field interacts with the field created by the two permanent magnets and makes the ribbon move back and forth. The ribbon can be small for high frequency use or large for lower frequencies. Just like with dynamic drivers, a ribbon-based planar loudspeaker excites the air which we (can) process in our heads into music. Another form of the planar loudspeaker is the electrostat. Compared to the electromagnetic principles of dynamic and ribbon drivers, the electrostatic driver is a completely different animal. It’s perhaps best to regard this type as one giant capacitor. An ultra-thin stretched membrane is attached between two rigid plates called stators. A very high voltage applied to the membrane often reaches 10kV. Once the audio signal is sent to the stators—the positive phase to one, the negative phase to the other—the signal creates an electrostatic field in relation to the incoming musical signal. That varying field now interacts with the static field of the membrane and makes the membrane move back and forth as it gets attracted and repelled by the stators. In moving this way, the air around the membrane is excited once again. The stators are perforated to avoid obstructions to the air flow. An electrostatic loudspeakers or ESL needs power from the grid to work. For the static part of an ESL aka its membrane, the polarizing voltage must be generated and the incoming musical signal stepped up from a few tens of volts to several thousands. The biggest difference with any other type of loudspeaker driver is that there is no physical contact with the moving ESL diaphragm. Only electrostatic forces make the ultra-thin film move. That film is lighter even than the air it moves. Being so thin, a dozen micron (12 x 10-6 meter) or less, also makes the diaphragm free of energy storage or self resonance. Colouration is no issue. Whilst we are at the benefits of ESLs, here are some more before we'll get to the liabilities (you didn’t think this was a free lunch, did you?). More...

Estaticar Posted November 21, 2014 Report Share Posted November 21, 2014 ... vise mi interesantno dokle je covek stigao entuzijazmom u danasnje kilavo hifisticko vreme,pa nek je i u 6moon-u Po svojoj konstrukciji je ovaj zvucnik blizi starom Quadu nego novom, kome je (vecem od dva) blizi po dimenzijama. Poznat mi je ‘istorijat‘ njegovog nastanka i ulaska na trziste SAD, i nesto mi govori da je rec o uspelom proizvodu. Verovatno bih i sam bio malo sumnjicav prema objavljenom testu da ne znam da su cetiri dugogodisnja korisnika Quadovih (i jos nekih) elektrostatika – koje sve poznajem, i korisnike i zvucnike – ovaj Soltanusov model satima slusali i svi mu dali dobru ocenu. Pretpostavljam da ce ovde biti jeftiniji nego u inostranstvu. A za sve ostale komponente (odlicnog i u potpunosti novog) sistema dovoljno je znacajno manje novca.

Estaticar Posted May 14, 2015 Report Share Posted May 14, 2015 U januaru je lista meni poznatih zadovoljnih slusalaca (videti #5) povecana na sest. Utisci vise nisu svezi, pa ne bih detaljisao, ali da me neko stavi pred izbor - Soltanus ili Quad 2805/2905, uzeo bih ovaj prvi. Koliko znam, Quad je u SAD ostao bez distributera, izgleda da danasnja kontrola kvaliteta nije na visini nekadasnjeg renomea ove marke. Soltanusov elektrostatik je jednostavniji za servisiranje, dok 'serviser' ne moze biti strucniji. Zavrsna obrada je odlicna, a za moj ukus je taj zvucnik i lepsi. Dok smo slusali, oko nas se vrzmao jedan americki emigrant po imenu Sammy, cija bi bronzana nijansa bila idealna za 'grilove' tog modela, ali bih se i sa onim crnim primercima lako saziveo.

Estaticar Posted May 15, 2015 Report Share Posted May 15, 2015 Pre lupetanja proveriti... Proveriti pre lupetanja? Stvarno lup... perkusionisticki savet. Informacija je mesecima stara i potice od dobro upucene domace emigracije, ali u dijaspori gledano sa americke strane. Ne moze biti jasnije. Ipak, da proverimo, jer na internetu sve pise - osim kad ne pise: http://www.quad-hifi.co.uk/Supportcountry.aspx?lang=En&Tab=America%2fAfrica US, US...? http://kemela.com/store/Quad.html kemela is a Quad HiFi Reference dealer covering Atlanta and the Southeast. AmeriÄki emigrant Za razliku od mene, Sammy je preleteo Atlantik i cuje do 33.280 Hz. Quote Link to comment Share on other sites More sharing options...

A za sve ostale komponente (odlicnog i u potpunosti novog) sistema dovoljno je znacajno manje novca. Cena za Srbiju ce na zalost biti ista kao i za Ameriku. Englesku i Papua Novu Gvineju.

Estaticar Posted May 17, 2015 Report Share Posted May 17, 2015 Cena za Srbiju ce na zalost biti ista kao i za Ameriku. Englesku... Mogu da se raspitam, ali ne bih da nastupam kao iciji (ne)ovlasceni predstavnik za stampu. Za Ameriku i Englesku vazi isto sto i za zemlju proletersku, a to je da se 'high-end' ceni i po ceni. Nisam siguran kako bi se njeno eventualno 'umanjenje' odrazilo na precnik kruga potencijalnih kupaca, kojih je za posteno napravljene zvucnike – i jos neke stvari – uvek bilo zalosno malo.
