Here is an image of our D26 high frequency driver mounted in a flat baffle. The white plastic baffle fits flush into our testing chamber creating a baffle that is flat for about 1.2meters squared.


Now, mounting the tweeter 8mm back in a small recess (as is often practiced, for time alignment) as shown...



The size of the recess makes a difference too. The reflections caused by the recess walls will affect different frequencies from the driver. To illustrate this, I increased the diameter of the recess in the baffle, but kept the depth the same:

這完全沒有任何的擴散或其他小道具，難道這空間其實暗藏什麼撇步？？

撇步就是無聲勝有聲,因為連線都沒沒接!
拍照用的樣品屋啦!!

While massive demand for G3 and B1 continues, we're looking at an all new production method for the cabinet of G2. Our pattern master, Vika Zwane, is seen here preparing the experimental G2 cabinet pattern. The benefit of this new manufacturing technique will be a lighter, stronger cabinet that pushes it's resonant frequency further and further out of band.




And while Vika prepares the new tooling, we are also having a good look at the performance of the lower midrange driver absorber tube for the Giya. The experiment below investigates the effectiveness of the decoupling method of the driver to cabinet.

個人意見：鸚鵡螺的外觀算是經典了~~ Vivid的外觀總讓我聯想到外星生物之類的....

Working the weekends to satisfy the intense demand for our G3 GIYA can be hard. Lucky we have a pair of G1 GIYA's available for some motivational music - keeping the factory pumping with some pumping tunes!

We are doing some power handling tests on the D50 driver - a routine test to make sure that the driver is to spec. Basically we drive it to destruction while monitoring it thermally and timing it. The source is pink noise generated by the small black box on the left. This is amplified by the VTL preamplifier before being fed into the 1kW amplifier on the right. This then goes through a filter that feeds the D50 an unattenuated signal from 800Hz to 3kHz.

The D50 is playing continuously at full power - unlike in music, with pink noise there is no rest time for the driver so it really is an extreme test of durability. After 20 minutes the dome of the tweeter was measuring 55 degrees C and the steelwork was over 100, and still she carried on! Everyone in our test area had to wear 20dB attenuating earplugs and I put a big muffler over the thing because it was so loud!

Here's a little video of our friends in Jarna, Sweden, having a good time with the V1.5's:
