Na mojim Audio Physic zvucnicima radi kombinacija koja je jako slicna ovome sto hoces da radis: Sradnjotonac / bas je Vifa 18 i tako nesto ( ako te bas bude zanimalo skinucu ga jednom i pronaci tacnu oznaku) Visoki je Scan Speak 9500 - nalazi se u modelu Tempo LE i Kalderi koja je oko 4 x skuplja. Ono sto je mozda zanimljivo je par reci konstruktora povodom razlika izmedju 9500 i 9700What is your favorite tweeter for the moment?- In the Caldera, we use a selected version of the Scan Speak 9500, a variant of the 9700. I feel that the copper ring in the 9700 causes an over-emphasized treble, so this 9500 has a aluminum ring instead. But it has to be selected samples. A problem with softdomes is that automatic coating by machines does not give optimum resolution. You have to do it manually by coating the edge and the top, maybe with different coating. So it depends a lot on skill. You can have two girls building the same tweeter. One of them makes tweeters with a tolerance of 1 db, another girl builds the same and the tolerance is 4 db. But when you want the best, there has to be some handwork involved. I am very satisfied with the Scandinavian driver manufacturers. They are very flexible, and they allow us to discuss different solutions. Just during the last six months, I have visited Seas three times.In the Caldera, you cross the tweeter at 1300 Hz. That is one octave under what common theory recommends today?- I think many cross the tweeter too high. Conventional theory has always argued that we should stay away from the fundamental resonance of the tweeter. On the other hand, mr. Thiele has presented new crossovers that are crossed exactly at the resonance point. I think that is very interesting. The resonance point is a very well defined area. The only you have to get rid of is the resonance itself, by choosing the right Q and a RLC circuit. Of course, the tweeter has to be very broad-banded, and very linear. But tweeters are more robust than many seem to believe. We have made tests at ScanSpeak with the tweeters used in the Caldera speaker. The voice coil was heated to 320 degrees and it did not break. We put 120 volt in, and we could see sparks in the dark, but it still did not break.
