    Audioman2122: Can you share the schematics of HIII? Please refer to my posts below for context. https://community.klipsch.com/index.php?/topic/200800-convert-cornwall-iii-xover-to-hersey-iii/ https://community.klipsch.com/index.php?/topic/201920-heresy-15-to-hiii-conversion/ Thanks & Regards

    Great to see another Heresy lover. Great job. Crites is great as well and I have great experience with Crites. Enjoy the system!

    Thanks @mustang_flht

    Independent of Bass, I find the refinement in upper mids to Treble and extension alone is worth the upgrade from H1.5.

    The Bass improvement with K28 over K22 is significant. There is more mid bass warmth and more fullness. Overall I find these awesome. I have had so many "so called" auidiophile speakers but none let me enjoy music like these even when I am in next room. I like this even more than my Cornscala I built 12 years ago.

    @Pondoro Not much really. The K22 woofers were replaced with K28. The original K53, K77 and Original crossover left alone inside. The K28 woofers directly connected to Binding post which is fed by the bass Section of New Crossover. I had originally just placed the new mid and Tweeter Horns on top the cabinet since the Motorboard of H1.5 is not compatible. I liked the sound stage with the raised Mid and Tweeter so I decided to make a top section cabinet.

    Top Section not veneered yet

    CANT - Do you still have CW3 network schematics info? If so, could you please share the same? Please refer my recent post https://community.klipsch.com/index.php?/topic/200800-convert-cornwall-iii-xover-to-hersey-iii/&tab=comments#comment-2636885 Thanks & Cheers

    Hello, hope everyone is staying safe and healthy. I need to convert my CW3 Crossover network to H3. The CW3 kit was originally bought to experiment with my cornscala. Couple of years ago I upgraded my Hersey 1.5 to H3, with CW3 Xover and K28, K53Ti and K107 Tweeters. And for a while I used a Autoformer to lower the mid and tweeter section by 3db. Now instead, I am using a RME DAC's EQ to lower mid and tweeter by 3db. But this only solves digital sources. I would instead like to make the network a proper H3 network. I checked with Michael Crites, he does not have the schematics of either. If any of you have schematics of CW3 and H3 and since both the H3 and CW3 are no longer in current production, could you share them ? BTW, I am in the process of building a top section cabinet (trapezoid) as I like the higher soundstage with the mid and tweeter on top of the cabinet. Thanks & Cheers

    I built y cornscalas 3 years ago but did not get around to finish them cosmetically until now. Finally it is all dressed up in Veneer, grill cloths, etc. Here are some pics. Once again my sincere Thanks to Bob Crites, James Cullison and Klipsch forum members. Cornscala Parts - K77-F, K55- V (Solder Terminals) / K400, Crites CS1526CW Woofer, AL-4 Network.

    I am back in the East Coast again. I will be here till Feb 3rd. The Tweeters are still available if anyone is interested.

    Lee: What OS are you running? While it works like a charm on XP, I cannot get it to work on W7 (and yes I followed all the procedures religiously).

    It is also interesting that the K77F is labelled as a 8 Ohm nominal Imp tweeter. From the plot the average Imp is only around 6 Ohms.
  20. radiogram
    This is K77F as measured by WT3. I am wondering what effect there maybe from what I see around 3.5KHz.
  21. radiogram
    Here is what WT3 says about K53/K701 combo. The impedence peaks in the midrange ain't so pretty! Also interesting is Le is repordted as 2.2mH higher than a Woofer???
  22. radiogram
    Al: The plot I have posted so far are for BEC's CS1526 Woofers (in my Cornscala cabinet) which are as per Bob close to specs as early K33's. I will be posting the K53 measurement next.
  23. radiogram
    Bob: Have you done Le measurements on the CS1526 at various frequencies with something like a B&K precision meter?
  24. radiogram
    Here is the measurement of CS1526C (mounted in cabinet) by WT3. I did more than 10 runs at different times and the results were quite consistent without much variation. Re is right on (my Fluke Meter measures 3.8). The WT3 impedence curve pretty much matches with my crude method above with a few minor exceptions at a few frequencies. Also, the min impedence between the double peaks is at 40Hz suggesting tuning to 40Hz. Interesting things are as follows: 1. Le is reported as 1.7mH (do not know at which frequency) 2. Qts, Qes and Qms are substanially different from free air specs (cabinet loading cause??) which are Qts = 0.2, Qes = 0.27, Qms = 9.93.

    After getting the WT3 tester under Windows XP (it does not work under W7), I measured the impedence and T/S parameters of Crites CS1526C Woofer mounted in a Cornscala Bass Cabinet. My Cornscala Bass bin has almost same volume of Cornwall but with different shape. It is rectangular the first 9 inches of depth and then tapers like a trapezoid towards the rear. The port shelf is same dimension and postion as of cornwall. First I will post the impedence I measured earlier with my crude simple method using a known series resistor ans measuring voltage. Here it is.
