    ...What should he use to test the caps with? ...Unless they are leaking oil, they are fine.....Never tested one in the lab, ove 22y, that was bad unless it was leaking.  Maybe heat up the joints on the network...as some of the points could need it. You may "hear" a difference once the caps are changed...but you can't test that...as unless you used the wrong part, it won't change. 


    Hi @Trey Cannon

    I meant to measure the µF and possibly the ESR of these capacitors, but if you say that this does not wear out then disregard what I said.


    You are the pro 👍

  2. Hi @jeffryder

    The capacitors of these networks evolve badly over the years, especially after more than 35 years. You should measure these capacitors to see the µF found and know if they are still within specification. If they are out of specification, consider changing them either by Klipsch aprouved or by replacing the same values in MKP 🙂

  3. Sometimes also the varnish of the coil swells and bubbles, resulting in the speaker working but no longer producing bass: in this case it is necessary to clean the air gap and change the coil. To check if there is not this defect, it is necessary to press delicately on the paper cone, the assembly must move freely without too much resistance.

    @MeloManiac  giving you something to read about " Krautrock " ...Have fun......


    From the end of the 1960s and beginning of the 1970s, the genre krautrock was used to describe the rock music of primarily West German bands, some of which became internationally known. In addition to their geographical origin, all classic Krautrock bands have in common a tendency toward experimental, improvisational rock music.


    The term goes back to the word "Sauerkraut" as well as the derogatory term "Krauts" for German soldiers in World War II. The origin of the word Krautrock, contrary to frequent claims, goes back to an advertisement by the German company Popo Music Management, which first used the word in the English magazine Billboard[1] to promote records by Bacillus Records. The term was picked up by the British press and used frequently. In addition, in May 1973, the Hamburg group Faust recorded their fourth LP for Virgin Records at "The Manor" studio in Oxfordshire, the first track of which was called "Krautrock". Virgin Records then adopted this term as a genre designation for rock music from Germany.


    In Germany, Krautrock was often used as a self-deprecating term for their own music, expressing the fact that Germany was considered a pop-cultural developing country. In the beginning, Krautrock was more of a collective term for music from Germany. There was neither a unified movement nor extensive stylistic commonalities.


    Apart from the use of the word "Kraut", which was not meant in a flattering way, this grouping of the most diverse styles and the reduction to their geographical or national origins also meant that the term Krautrock was often understood as a pejorative term. For example, Amon Düül and Agitation Free were committed to psychedelic rock, Tangerine Dream tended more to the realm of electronic music, Guru Guru initially practiced space rock à la Hawkwind, Birth Control could be assigned to hard rock, while Can chose an almost avant-garde compositional approach. Overall, the bands often distinguished themselves with their own interpretations of Anglo-American patterns, which also brought international recognition.

    Although there were bands early on that sang in German as a matter of course (Ihre Kinder, Prof. Wolfff), German lyrics were by no means considered a matter of course in rock music at the time, and instead of switching to English, some Krautrock bands chose to dispense with lyrics almost or entirely (Ash Ra Tempel, for example). The proximity of many bands to extra-parliamentary resistance and leftist groups (Floh de Cologne, Ton Steine Scherben, Lokomotive Kreuzberg) is remarkable. Agitation Free had their practice space in the K1 and often played at actions of the Haschrebellen. It is also worth noting that groups like Omega (Hungary) and Nektar (GB/USA) are often counted among the Krautrockers because of their success in the Federal Republic Germany .


    The only common basic tendency would be the tendency to more complex structures, which results in a close relationship to progressive rock/art rock and jazz rock. From today's point of view it is to be emphasized that here conspicuously many musicians experimented with the at that time new synthesizer technology. Apart from Can, this applies above all toTangerine Dream and their entourage (Klaus Schulze, Ash Ra Tempel), who thus possibly provided the basis for the later worldwide success of Kraftwerk (Autobahn, 1974).


    Enough now ....


    Hi les gars 😎


    I have this album for at least 40 years, my copy is an original UK 1973 press, I 🧡 german music !


    Faust IV, look on my pics first title on side A = Krautrock 👍

  5. Hi @Schu


    I don't know if this will help you but be aware that there are pro multi-channel amps, very good for sound and cheap for the stock market. Often they are 4 channels, you just need to take a small pro amp for the fifth channel, there are cheap ones between $ 100 and $ 400


    For example



    even with DSP



    Example for channel 5


  6. Hi men,

    I am interested in a Class D amplifier from Lab Gruppen PDX3000. Could someone tell me which module it is: NCore, Pascal-audio, native Lab Gruppen, other ...
    It has a DSP so I want to put it in the bass on my Cornwall III's K33E in active filtering and put my Cary SLI50 on the mid-high horns.
    In your opinion is this Class D amplifier of good quality for Klipsch Cornwall IIIs.

    Hey man, everything old is heavy duty compared to the new stuff:)

    Hi men,

    Yes at home in my region many monuments are big and heavy, because they date from the middle ages or antiquity, there are castles, fortifications and churches of the middle ages and aqueducts, theaters and ancient arenas of the Romans: it's beautiful 🤩


    Around 15/20 miles of my home
    Romans: Pont du Gard, Arena of Nîmes and Arles, Ancient Theater of Arles, Square House of Nîmes, Glanum of Saint Remy de Provence ...
    Middle Ages: Palace of the Popes of Avignon, Pont d'Avignon, Castles of Tarascon and Beaucaire, ramparts of Avignon, many churches.


    I have to look for the photos (Here we have just started the 3rd containment of Covid 19, so I have time at home 😪)

    The CWIV filter that I put on page 14 is a Rev A, this one is a Rev B, so it seems to me that this is an evolution of CWIV



    Hi @dls_123


    On your recent version of CWIV there will certainly be network B. Look at the diagram of version B,  @CANT has read the capacitor values for you 👍😎


    It is not obligatory to change the values to //, so change in priority 7µF, 2.75 and 2.25µF :)


    For the resistors, I think it's 8 and 30ohms, look at the diagram of CANT, only 30ohms and in series on the signal!

    I wonder why it was built so heavy duty? It was a lookout, right?



    Yes, the Carbonnière tower is mentioned for the first time in a text dated 1346 which provides details on the function of the structure: it says that "this fortress is the key to the kingdom in this region. "

    Indeed, located in the middle of the marshes, it was the obligatory passage to reach Aigues-Mortes: its crossing was subject to a toll. It was manned by a garrison made up of a squire and several guards. The terrace could support up to four pieces of artillery.


    Aigues-Mortes is the fortified town from which Louis IX's troops left for the crusades. Fortunately today the inhabitants are calmer.


    I will put you some pictures of the ramparts if I find them

  10. Hi @SpeedLimit


    Here I simulated Type A electrically.

    2 small difficulties:

    1 - I cannot put the tweeter on when the midrange is not filtered by a series choke, because the software simulates a high response. Whereas in reality the medium drops naturally and that's why Klispch adds a tweeter with 2 µF above. When there is the 0.5 mH self I can simulate. I would have had to manage to simulate the fall of the medium above 5 or 6 kHz, but for the moment I do not know how.


    2 - without inverting the phase of the woofer, there is a hole around 400Hz, but this is not necessarily the reality, because the load in the horn of the woofer can be the phase acoustically: that I do not know and it would be necessary to measure : or do the phase inversion test of the 2 boomers to see what you like the most.


    Also be careful, you may need to adjust the level of each speaker when listening.


    For the moment I have not simulated Type AA, we will see later.



    En français : 

    Voilà j'ai simulé Type A électriquement.
    2 petites difficultés :

    1 - je ne peux pas mettre le tweeter quand le médium n'est pas filtré par une self en série, car le logiciel simule une réponse dans l'aigu. Alors que dans la réalité le médium chute naturellement et c'est pour cela que Klispch rajoute un tweeter avec 2 µF au-dessus.Lorsqu'il y a la self 0,5 mH je peux simuler. Il aurait fallu que j'arrive à simuler la chute du médium au-dessus de 5 ou 6 kHz, mais pour le moment je ne sais pas faire.

    2 - sans inverser la phase du boomer, il y a un trou vers 400 hz, mais ce n'est pas forcément la réalité, car la charge en pavillon du boomer inverse peut être la phase acoustisquement : ça je ne sais pas et il faudrait mesurer : ou faire le test d'inversion de phase des 2 boomers pour voir ce qui te plaît le plus. Attention aussi, il faut peut-être ajuster les niveau de chaque HP à l'écoute. Pour le moment je n'ai pas simulé Type AA, on verra plus tard



    Type A without electrical phase inversion and without tweeter, beware the acoustic result may be different because of the load and the midrange curve without the tweeter.

    Type A sans inversion de phase électrique et sans tweeter, attention le resultat acoustique est peut-être différent à cause de la charge et de la courbe du médium sans tweeter.



    Type A Phase inversion



    Type A 0.5mH + 2µF




    Type A 0.5mH + 4µF

    Hello mustang_flht


    yes, i can try this ..  i just have to find 3,9 and 12µF caps ..


    I can try this while waiting for the arrival of my components to do the filter at 6dB / Oct like that of Bob crites slightly modified (A-4500 with change of the 2μF capacitor by 4 μF and addition of the self of 0, 5 MH in series with squawker)


    And now some pictures of my Iwata horns






    Hi @SpeedLimit Afterwards, if you like a sound that is a little soft and not aggressive, I like to dig a little in the upper midrange around 4000 Hz. If you want I can calculate that easily.
