    No middle ground?


    I like you fine, but in this I categorize you as "over the top."


    I like your power distribution yard analogy.  I made a ton of money working in them.  Where's the hollow aluminum tubes?  ;)

    Yes, I know "the golden middle" is mostly the right way. Me ? too extreme? I think spontaneously of Youthman, who has produced a new video on youtube with only "50 pairs" of Klipsch boxes that he owns. I only have 2 speakers ! At least something that Youthman doesn´t have.   Good Idea...the hollow alu tubes :wink:

    Gorgeous set-up!  I love those crossover boxes. I love what you've done.


    I love listening to music, I really do; I am a fiend for accurate sound reproduction. But I am also a gizmo-gadget loving guy. I don't just want a Timex, I want a hand-built, hand-polished, Swiss-made timepiece that is as beautiful as it is functional. You, my friend, do it good. I get you.

    I'm looking forward to it. :emotion-21:

    You can take anything to an extreme level. No doubt your speakers cables look exquisite, but its serious overkill. PWK advocated ordinary zip wire which some peeps here gasp at. No doubt technology has improved in a big way, but simple physics do not change. My McIntosh amp users manual indicates 16AWG is suitable for 300 watts for a < 50' single run, 8 ohm load. I make up my own using quality 12 AWG and banana plugs, < 15' single run........overkill.


    Same with your crossover mods. Taken to an extreme level, and an external passive XO. Hey whatever floats your boat. RF-7s are pretty impressive when they leave the Klipsch factory, what level of improvement do you expect from your crossover extensive mods?


    For some it seems to be almost a sickness, an obsession.

    If you read my first posting, you will find that I always liked the original Rf 7 MK II, otherwise I had not bought it. When the MK III came onto the German market, I wanted to buy it first. But she didn't blow me away. That's why I preferred to start this project and build my own MK II. I only did that for myself. It was worth every penny. And yes, I value perfection when others overkill, okay, so I can live with that.

    Wow! Lots of descriptive words. Any before and after O scope test results? 

    Glad you think it's soooooo much better. Maybe Klipsch needs your help?

    The measurements and diagrams of the measurements will come. This entire project has now taken a good 14 weeks. I am exhausted, need a little rest for now and actually just want to listen to music at the moment. In about 14 days I will then again deal with the technology and carry out the measurements mentioned above. I just can't anymore ... at least for the moment. Such a project costs a lot of energy. It would be my dream to be invited by Klipsch ...

    Bright & clean looking listening area with that fascinating stereo rig front and center.

    With the ten point bucks above looking on... mine are in the yard although it's just been the does and young ones the past week.

    Too bad Paul. W. Klipsch can no longer see it. I think he would say, like Mr. Spok from the TV series "Spaceship Enterprise" .... fascinating ......german engineering ;)

  6. .. and this is how it looks in my music room, it has the name "Little red cathedral" now connected with my RF7 MK II Queen.


    For over two hours now my queen has been controlled by these nine external crossovers. The impulse speed, the jump response of the chassis, the "timely" and plasticity and depth gradation of the stage, voices, instruments, location, dynamics, fine resolution, coarse dynamics, fine dynamics, precision, spatial resolution, from the brilliance of the high tone to the depth gradation of the bass has improved so much that I am currently missing more words. I still cannot grasp and understand all of this. These are RF 7 MK II against which an MK III, I had it here in my music room for listening, did not have the slightest chance. At least that's my personal assessment. And the entire system has just been born and will continue to develop. I am looking forward to what will come next.


    Now I have to enjoy "Kingfish & Buddy Guy's" - FRESHOUT- See you later

  7. The small wiring errors I caused on the new external crossover itself have been eliminated. It went faster than I thought because I had support from a good friend who had helped me to fix it today. It was done in two hours and the external crossovers are now working propNow you see the first pictures of the new crossover. A conventional crossover has a circuit board on which the resistors, coils and capacitors are installed. With a freehand wired crossover, the components are usually attached to a base plate and connected to the inputs / outputs a conventional cable wiring to the speakers.


    My crossover is, let's call it "negative replica" of a switch, the solution is another. All components are installed in a housing on the base plate. There are 4 OFC copper power lines above the components. These are directly connected to the inputs / outputsAll coils, resistors and capacitors are directly connected to these "live cables". This is the shortest and most direct way imaginable. It works like a "power substation". On the ground, the customers are in the air hanging the lines. The potential of all components is thus fully exploited.. All coils, resistors and capacitors are directly connected to these "live cables". This is the shortest and most direct way imaginable. It works like a "power substation". On the ground, the customers are in the air hanging the lines. That is my basic idea for the development of the new crossover. Therefore the large housing. The potential of all components is thus fully exploited.At least that is my opinion........

  8. just a quick update. I'm about to finish my project with the external crossover for my RF7 MK II Queen. I  have already carried out a first test setup. I have to make some internal crossover wireing changes before the whole concept can be completed. You will find out more details in two or three days.This is a picture of the first test setup, the crossovers are located on the left under the tape machine and on the right under the turntable.Further details coming a.s.a.p.

  9. I actually wanted to sleep for a long time, but by chance I found this new CD that was released in Germany .. Christone "Kingfish" & Buddy Guy with "fresh out".

    John Lee Hooker would be jealous. I bought this CD immediately .....I LOVE THE BLUES .....By for now ......

    How Some Folks give someone a hard time over something they have zero experience with is just wrong. Just human.


    Have to get on the waiting list before 2-11 and you'll get a code to be able to get a ticket or two. Darn I made a promise and it's going to be six miles up the boulevard:(

    Don't care that they're old at all.
