Talking about the drivers that we wanted that extra bass but at the same time retaining the midrange performance. So it is always a trade of when you do a speaker between various things. If you do something over here, it will get different over there so you are always changing a lot of things at the same time. Acoustic is a more or less exact science but there are many unknowns. So sometimes, you have to work with intuitions. If you see a shape, say, this wont work like a diameter of a voice coil. But it is not simply saying "Lets go for this diameter, this will work." No. We made samples after simulation and checked if it worked. So it was a lot of work to get this driver right. Because every detail counts. Getting a bigger diaphragm was one of the things we wanted. So we had a bigger surface area on the diaphragm. We also have a stronger magnet in a different configuration than what we used in the current or the past Contour. So there is a lot of things that has changed in that and it is all in the chase of getting that very good mid-range and at the same time retaining the bass response. We still use high quality injected baskets. We changed from what we called the inside magnet, which is a tradition system in the Dynaudio to an outside magnet because we could simply put larger magnets and one of the goal of the new Contour was trying to keep the quality of the bass but with more dynamic and with more output that means you can play louder. It should be fast. It means the diaphragm has to respond very fast to the signal. The shape has been ordered or the material itself has been studied from thickness and shaped to have a better mid-range performance. That means it is more open, more natural. Surrounds, spider everything has been redesigned. As I said before with simulations to get the perfect driver for this purpose. And the results are that, the listening we had so far, is like we get a way better stage like you could almost see the instruments between the two speakers You can point them. Not only in the position between the speakers but also in the depth and also if the singer is standing and the voice, the mouth of the singer is above, the tree the speakers while it is actually above and not on the level of the speaker where it is often is if the driver does not perform as it should. It took us very long to get it right and we got there and we are happy and also very proud to have the whole team to design a new driver. Which will be also the base of newer design, which will come in the next generation higher and speakers from Dynaudio in the future.
