I have got a classified today from Italy via hifishark search engine. I have to ask for some more info (does it work properly etc) and if he will ship to Germany. https://www.subito.it/audio-video/coppia-di-diffusori-klipschorn-kc-fr-brescia-551907619.htm I have read the pages with the codes here in the forum, so this Khorn was built in 1973. Then it has K-33-P woofers (CTS Paducah KY). Are these ferrite or alnico bass drivers? just for the know, no dealbreaker in any case. It should have an original Type AA xover. I think the price and condition is very good from what I can see. I can not find any info which wood venner „FR“ should be. C = non colared. May be it is Fir Raw? -

From the Stereophile measurements: "The La Scala will work best with amplifiers that are not fazed by 4 ohm loads," Make sure whatever you build has the correct OPTs for a 4 ohm load or multiple taps. -
I think it is an extremely good idea Thanik... get away from high damping and get tube rolling because the music lives in the mid-range. -
85dB is louder than most realize. Twice the power nets a 3dB volume increase. 10X power increase nets twice the volume. For most, the smallest increase they can hear is a 3dB increase in volume. One caution for extended high volume listening that can cause a vicious cycle: over time the drivers’ voice coils heat up. As a result, their impedances increase resulting in compression & volume reduction. The unknowing listener reaches for the volume knob… my 2 cents -
With very low level signal at say 5kHz put your jumper across the 2uf cap. What happens? -
Not paying the prices they ask these days. The only one I wanted to see but didn't see was Elvis. My parents saw him in '69. They were excited in a way I didn't see often. -
Also, in case your are wondering, if you recording got dynamic or loudness all way to the top! https://www.dr.loudness-war.info/ even in Hi-res, like old days, computer teachers said: Garbage in - Garbage out, even if the bag is gold...! best regards ps https://www.audioholics.com/how-to-shop/best-free-audio-software -
