Stevenarrow Posted November 28, 2016 Share Posted November 28, 2016 Hello, I've been breaking in a new Faital Pro HF206 on a K510. So far, my experience has been excellent. The driver is crossed around 1000Hz, but should go a lot lower. I am running it in my Altec Valencia cabs. -- I received the following info from the manufacturer regarding this new driver when asked about how it compares to the 204 and the 200: The HF204 and HF206 are exactly the 2" versions of the HF144 and HF146 respectively. The difference is in the air gap's geometry and treatment. Basically we reduced the volume of the air gap (so under the diaphragm) and added absorbent material. The end result is visible in the response curve in the mid-high freqs. It has a flatter (less rising) response above 1.5 kHz. While for the difference between the Titanium 3" VC and the Ketone Polymer 2.5" please know that the differences go beyond just the material because they are indeed two mechanically different compression drivers. The HF200 has a bigger VC hence a bigger volume under the Diaphragm in the air gap. The phase plug is a 3 slot phase plug and the titanium diaphragm is one piece with the surround so it may result in a slightly more nervous higher frequency but also more efficient because of its higher reactivity than polymers. On the other hand the HF204/206 have a 2.5" VC with a whole ketone polymer diaphragm and a 4 slot phase plug. This all together gives these compression drivers a smoother and more linear response throughout and up to the very high frequencies. In the higher fequencies the "sound" may result smoother than the titanium. One final word on Ketone Polymer, it is a very peculiar material because it is a polymer which is loaded with mineral while being sheeted. This allows it to retain the polymer's elasticity but it also gives it a higher rigidity and capability to withstand heat better than other polymers used in these applications. Therefore we consider it to be the best compromise between commonly used polymers lime Mylar and metals like aluminum and titanium. 1 Quote Link to comment Share on other sites More sharing options...

Stevenarrow Posted November 28, 2016 Author Share Posted November 28, 2016 Agreed. I was pleasantly surprised to get a firm and detailed response so quickly. Quote Link to comment Share on other sites More sharing options...
Stevenarrow Posted December 7, 2016 Author Share Posted December 7, 2016 Quick test in room last night: HF206 on K510 over an Altec 16" in bass reflex. Quote Link to comment Share on other sites More sharing options...
Chris A Posted December 7, 2016 Share Posted December 7, 2016 What are you using to cross over and do EQ? Chris Quote Link to comment Share on other sites More sharing options...
Stevenarrow Posted December 7, 2016 Author Share Posted December 7, 2016 Using custom XO made by Werner of Jamo Speakers. There is adjustment built into the XO, but no EQ. Quote Link to comment Share on other sites More sharing options...
Deang Posted December 7, 2016 Share Posted December 7, 2016 Something bad happening around 500Hz. How does the knob control the output of two autoformers? 1 Quote Link to comment Share on other sites More sharing options...
Chris A Posted December 7, 2016 Share Posted December 7, 2016 That 500 Hz thing is probably boundary dip: 1/4 wavelength at 500 Hz is 6-7 inches-which is likely the height of the microphone off the floor, or the distance from the K-510 mouth to the front or side wall.

Dean, I figured you might be the guy with the best guess on that. I have tried to reason it out using common sense, but I don't have a clue.

Deang Posted December 7, 2016 Share Posted December 7, 2016 I thought the Valencia was a two way - so I can't even figure out why the network has two autoformers. One of those might be a low pass coil - but I don't understand the wiring scheme. Hey, I just build the stupid things - never claimed to understand them.

Stevenarrow Posted December 7, 2016 Author Share Posted December 7, 2016 The 500Hz issue is mostly physical. The horn is on top of the cabinet: quite far from the woofer. Its just loosely placed up there for now. The dial allows a slight adjustment of starting point for the high range. The terminal strip on the lower right sets output volume.

Bacek Posted January 25, 2021 Share Posted January 25, 2021 Anyone tried HF201? Looks flattest from HF20x bunch. Quote Link to comment Share on other sites More sharing options...
