    Crites CW1526C - undiscovered potential?

    in Technical/Restorations

    Posted

    Hi everyone,

    as some of you know I've built my Cornscalas last year. Since I tried to get better bass performance I simulated different woofer chassis and founf out that I made an construction mistake - my bassreflexport is to long.

    While simulating I've tried different BR-port measurement I would like to share and discuss.

    Green is my actual faulty design
    Yellow is the original Cornwall port measurement (remember, this speaker was designed for the Klipsch K-33E)

    and finally red is what I could get with the Crites CW1526C.

    The big question ist: Since the Crites woofer differs from the K-33E, could it be the case that there is unused potential? Looking at the graph I would think so. The red line is just outstanding. Using just an 5 inch port length!

    What do you think?

    Changing Crites Cornscala Crossover Frequency?

    in Technical/Restorations

    Posted

    Hi,

    I'm driving an Bob Crites Cornscala using all the parts from Bob, including his crossover.
    I recently read about someone who changed the lower crossover frequency from 500Hz to 600Hz, getting a relly good result.

    Since the DIY world is kind of an "try and error" experience, I thought about trying a 600Hz crossing so that I could build my own opinion.

    Is there someone who already tried this? What do I need to change? The soldering will be no problem, but I'm pretty new to all the crossover topic so I don't wanna fool around with the crossover without fully understand the theory behind it.

    I appreciate any advice

    Thanks, Robert. That wall looks great. Holding it off the back wall allows room for wires, and those cool lights. You did the work yourself? Very handy!

    Did you apply the gloss finish to your speakers yourself? I'd guess you had to take them to an auto finisher. I would be terrified of having to transport them home, up stairs, etc.! How durable is the finish? Again, it's a striking display.

    Thanks for all the warm words. The slate wall is my work.

    The speakers were done by an auto finisher...it's really durable but it took 3 guys to carry the speakers without getting any scratches [:)]

    Very nice! Now, tell me about the wall on which the monitor hangs. Also, do you have an English version of your German Klipsch forum?

    The wall is made out of real slate. I used silicone to glue them on a wooden subconstruction.

    For the forum: You could use the Google page translator! Posting in english won't be a problem...as a member you can also browse the user-gallery where you can find some pretty nice setups.

    Hey Germerikan,

    thanks for summing this up. I also think we had a great time and I'm kind of proud that we made this happen only one year after starting the www.Klipsch-Forum.de or "Paul's-Reference" as we call it.

    At this time I also wan't to thank Amy Unger. When I had the idea to start my own Klipsch forum, we where like 10 guys writing about Klipsch. Right now, after one year, we count 154 members with 10113 posts. Impressive for just one year. Amy believed in the idea and helped me with the legal part (using the Klipsch logo and name). As you can see, it paid off.

    Sounds like a great amp!

    To cite Austin Powers: "Oh Behave!" [:P]

    The hard part for me is to decide what to do now. I could go for the pre- end- combo...but then I would have to make a Cornscala center speaker [:D]

    well well well...

    The amp which kicked my Cornscalas...

    After
    completing my Cornscala I was pretty thrilled from the heritage sound this
    3-way speaker was giving me. Coming from an RF-82 I made a huge step especially
    in the mids and the hard and well controlled bass. I was still using my Pioneer
    Elite AVR and was looking for some stereo amps to see how far I could go with
    an amp.



    At this
    point I have to admit that I was pretty skeptic about this "amp sound" topic. I
    had the opinion that all amps sound pretty similar, after I had compared few
    amps with my RF-82. But as you all know that this hobby can be pretty
    addictive, I couldn't stop trying with my new Cornscala. So I checked a
    Raysonic tube (3500$), an older Marantz PM-17mkII, an Italian Lector Amp (1500$
    considered as best-buy) and another big Denon AVR (2000$). With some of them,
    there was a difference but not in a positive way. The Marantz gave me pretty
    smooth but bloated bass, the Lector lacked it. The Raysonic sounded, as crazy
    as it sounds, pretty much as my Pioneer Elite. The Denon sounded warmer and had
    better bass control...but nothing special and worth an upgrade. So at this point
    I was pretty sure to stick with my Elite.



    At this
    point the review of a German amp called Aaron No. 1.a coughed my attention (http://enjoythemusic.com/superioraudio/equipment/1008/aaron_no_1a.htm)
    and as I knew that one of our famous Klipsch dealers in Germany was pretty keen
    with Aaron too, I gave him a call and asked him for a demonstration. We figured
    out a day and he came to my place with a fine selection of electronics as you
    see can on my picture.



    Well...and to
    make a long story short: This set was kickin' my Cornscalas. The bass control
    was simply stunning. Using a Crites crossover I knew that the 15" woofer was
    able to cause some amps trouble which often resulted in lacking deep and hard
    bass. The Aaron was able to deliver pretty intense bass punches, making my
    RW-12d redundant. Concerning the mids the biggest improvement was the gain in
    detail and the ability to reproduce especially female voices so emotional that
    I got goose bumps. It was like Alicia Keys was standing right in front of me J pretty awesome experience.



    Verdict: If you have the opportunity to try one
    of those amps (and I'm pretty sure you'll find a retailer in your area) I would
    consider a listening test. Considering its look and feel, the stability even at
    1 ohm and the ability to get Alicia Keys in your living room, I'm pretty sure I
    won't be able to resist and have to buy one.

    Cornscala III from Italy & Oppo BD 83 SE Modifications

    Hi Robi!

    how are you changing the crossover of your cornscala? You have to go a few dB down on your tweeter and your squaker afaik.

    The problem is that especially the midrange is very efficient and the woofer of the Cornwall III is the critical part. By damping the inside of the woofer you're loosing more dB from the woofer...so the original Cornscala crossover will cause you under represented lows...
