Okay so check this out. Look real close at the ECT. Look down inside to where the horn ports into a chamber at the bottom. There's a very fine mesh screen. Just past the screen there's something. What?
Then take a look at the lateral x-ray. What? You don't have x-ray? Good thing I do!
The horn curves down to a port that opens into a cylindrical chamber. The chamber is partially filled with something. What, I don't know. X-ray only shows density. All I can say, whatever it is, is less dense than the surrounding material. The space above appears to be the same density as air.
In other words, this thing looks EXACTLY like a horn speaker. Only with a chamber instead of a driver. In other words, it looks EXACTLY like a bass trap. Only, if you understand how bass traps work, one designed to work on very high frequencies. On the order of 40 kHz, I would say, http://www.sengpielaudio.com/calculator-waves.htm
Hard not to notice the distinct similarity between the ECT, PHT and HFT. My hunch is they all work on essentially the same principle and are simply sized or tuned a bit for different applications.
This would explain why the ECT works so well on my tone arm, even though to go by what SR says its for electronics. But it works great on my arm.
One of the first things I will do when I get some time this weekend (after a good dose of time bathing in the splendor of amazing sound I'm experiencing lately!) is try the ECT on my cartridge. Then when I get PHT will try them on the arm, etc. Meantime for the guys with HFT, would be nice to know if they work on turntables, arms, components. As I think they will....
