Gee, you changed the wallpaper........
PS. and a question to those speakers....
Don't you experience problems with the large offset of the tweeter, like that it tends to create two sweetspots that only match at ONE point in the room....?
I had to play with my setup quite some time to find the right position for listening.....My speakers are OB's with vintage Telefunken units, tweeters are by far not as much offset than the Transparence one's (pictures of the final version of my baffles to be posted soon).

Re: 15khz
Konnichiwa,
I was not picking nits. I was ACTUALLY answering your question. If I where to put this into loads of verbiage I would note that the function of the Supertweeters is not to supplement or fill in missing treble from the main unit.
No, the question you are asking is framed from a context that does not understand the function of the device. It is like you would ask "How can you operate this transistor with 4V Heater Voltage when the rated Heater Voltage is 12V".
The only answer to such a question would be to point out that transistors do not have heaters.

PS, do not ask me to explain the function in detail, suffice to say that the configuration is the result of empirical search for a specific subjectively percieved result and that in order to achieve this result the Supertweeters require position as shown.
You cannot apply the same principle AT ALL to "fill in" tweeters (such as the Saba's) but only to true "super tweeters" and there it is as applicable to multiway systems (such as my Tannoys) even such that are percieved as offering "full range" treble (conventioanl Cone/Dome systems for example).

powerfull option
Hi Flyingman,
you need a powerfull tube-alternative. I finished my 833 amp last year with great succes. Although (of course) someone will argue that low wattage power amplifiers are musical than these behemoths.....please do remember that you never listen to only the amplifier but to the whole chain of audio-equipment.
Here at my house i've heard an original Kegon-C (with the silver opt's) but with my 92 dB speakers that was not very good. In contrast with my 100 W 833-amp. A huge soundstage, good articulation and details en authorative bass. And of course endless (relative) power.
Home-made. And no: it is certainly not like the Wavac. I did not skimp on the very essential power supply ! It took in total 32 transformers, chokes and coils to come up with an 280 kg amp:
- 2 monoblocks with seperate powersupplies
- input transformer - 6SN7 - interstage - 300B (very nice DRIVER) - interstage - 833 - output transformer
- at 1400 V a get 100 W class A
- currently i switched to "only" 1000 V....and have 70 Watts on tap.
It doubles as a nice heat changer as well.....not surprisingly with 10 V / 10 A filaments.
But it will take some effort to built !

Mr. Willis' page is here.
In my opinion the driver stage is a bit weedy for a big valve like an 813.
An externally hosted image should be here but it was not working when we last tested it.

I'm going to build a GM70 amp hopefully in the next 2 years. While I'm gathering the iron, I get some of my inspiration here:
