  1. found this wonderful old thread that answered my questions (see below). i now understand that the combination of the first capacitor, the autoformer tap used and the resistance of the mid-horn are determining the high pass setting and output level for the mid-horn. then the capacitor in front of the tweeter sets the high pass setting for the tweeter. bottom line is that it looks like the 2uf capacitor in front of the tweeter needs to stay as is in a type e network.
  2. thanks for the explanation. what i don't understand is what are the appropriate steps to lower the mid-horn/tweeter crossover point to 5khz besides changing the capacitor before the tweeter to 4uf. are you saying you should also move the mid-horn down to tap 1?
  3. got my davea smahls with de120s installed a couple of days ago. installation was super simple -- the lens was a tight fit in the existing opening. sounded a little rough for the first 5-6 hours, but smoothed out nicely after that. high frequencies are much more detailed and airy -- i'm quite pleased with them! thanks so much @Dave A! i haven't replaced the woofers yet -- i'm not dissatisfied with the bass i'm getting right now. just going to enjoy the tweeters for a bit first. i'm interested in the idea of lowering the crossover point from the mid-horn to the tweeter, but don't understand what the two capacitors are doing. the first capacitor in the circuit is before the autoformer so should have an impact on both the mid-horn and the tweeter. the second capacitor looks like a high pass filter on the tweeter (at 9khz). what does the capacitor before the autoformer do? is the mid-horn basically running full range? seems like changing the capacitor before the tweeter would change the high pass filter to 5khz, but it doesn't seem like you'd want both the mid-horn and the tweeter active between 5khz and 9 khz. please school me.
  4. Cornwall 1s? If so, I'd look at the serial number again - you'd expect the 4 to be a letter instead. Can you get a pic?

    You can leave the asking price, the helps everyone understand the market. I'll leave it here . . .

    I know you can -- I'm asking you to reconsider for the good of the community.

    Most folks just change the title of the thread to include SOLD. Take a look, there are many done this way.

    @Westcoastdrums - why do you trash your listing when sold? Listing history is helpful documentation for the whole community. . .
  9. @svberger - congrats! I'd love to find some nice cornwalls like that!
  10. @Ruben abell if they have screws on the back, then they are cornwall 1s. As @dtr20 said, there should be a letter in the serial number - it should be on the paper label (where you probably saw it) and stamped into the top edge of the back. One place may be easier to read than the other.
  11. I think the 300 integrated would be more than enough. It's also $1k cheaper and puts off much less heat.
  12. it is true that i couldn't find any diaphram info on the crites website. i also couldn't say what jim and jem has. can't hurt to give them a call -- they both tend to provide good advice.
  13. as mentioned above, critesspeakers.com is a long time, respected supplier of parts. also jemperformanceaudio.com is a supplier of official klipsch parts.
  14. . . . removed due to incorrect information . . .
  15. wow, congrats! that's one beautiful amp.
  16. nice! wish i had something like that close to me.
  17. @jfjacques -- just go to a glass shop (the kind that does shower doors, etc.) and get them to cut some for you. won't cost much at all.
  18. Luxman SQ-N150 integrated. . . . What he said. . .
  19. My recordings of So What have the same thing -- it's the recording, not your system.
  20. I'd enjoy them as they are and decide on updates later after you get to know them. I've got some 1975 Heresys with the same tweeter and mid-range - they sound wonderful (only the caps have been replaced). I love the idea of upgrading electronics first. I was told that either diaphragms work or they don't - the Ti diaphragms will certainly change the sound.
  21. Note the jumpers on the back. When you remove the jumpers, you are removing the amp portion. The pre out will variable out, not straight line out. The pre out will send whatever is selected as the input including the phono section.
  22. @Oicu812 gave you some very good benchmarks. Just as an FYI -- the serial number indicates that they were made in 1988, not 1985. Best of luck!
