    Old K'horn photos being posted - finally

    Thank you, THANK YOU everyone! You very nice comments, certainly make all the work and photography worth it! At least you are enjoying the process just as I did...

    To note, I am not sure about the mounting machine screws for the original K-77 tweeters..

    ---Marvel--- the machine screws ares the SAME that holds K-55 horn as well, and too large a diameter for the mounting holes on CT-125's, it just would not fit...

    I'm sure its all original, as the grillwork has never been removed, ie, staples around the front baffle look totally untouched, and the only way to have made any changes to the mounting hardware. Strange though... Guess mine are made with different threaded rods then they use in more recent models ??

    But, at any rate... I brought my Adcom 545 home tonight and will set that up on Saturday for some listening tests. Its only 100 watts a side, so it should be ok with the K'Horns for now. Let you all know how they sound.

    Small bit of history for you all....

    I ended up buying the Adcom instead of the NAD amp because it had a wider soundstage then the NAD amp which I so badly wanted instead, as it matched the NAD preamp it had just bought. But, after a good 30 minutes of going back and forth with the same music excerpt (Strauss - Four Last Songs), the Adcom sounded like stereo, the NAD amp sounded like MONO.... go figure! I had to trust my ears and NOT my brand loyalty on that one [;)]

    Again, thanks everyone that has responded, really appreciate all of your kind notes!

    Kind regards as always,

    Gary

    Ok guys, sorry to see things get heated here........But, I was curious by the title of the topic. I have a Pinnacle DC sub-350... Its an interesting design and the company has recently added much a larger amp to the same double 12" driver design. Its a band bass and acoustic suspension setup in one cab only 14"s square. There is NO limiter on this sub, you can crank it and hear distortion at very high levels but NEVER a bottoming out! Great for movies, plays down to 21 Hz..

    In addition to this, I built one of those `water heater' subs! Mine is different. Most all are a long and TUNED concrete former . I went with a SEALED 24" diameter Sono tube. The driver is a SQUARE 15" automotive subwoofer. It stands only 26" high with an interior space of 6 cubic feet which is MAX for the Kicker driver within. It is powered by a Carver 400M (driver is coasting here - cont. rated power is 800 watts!) driven by a Behringer PRO X crossover.

    I set this one to START at 18Hz. and down...! I got 101 db on a digital meter (C weighting) at 14.8 Hz. 15 feet away !!!

    Also in my collection is a Velodyne F1500-R..... (only 250 watts) This sub plays very low, but is more subtle in nature. I tested this one in a high end audio salon BEFORE purchasing it with a TRUE signal generator.. It managed a strong output down to 15Hz!

    I have extensive photos of my `water heater' if any are interested to see.

    You all know me by now (68 K'Horn project), my Canon SLR is always busy [;)]

    PS. NOT using any subs on my K'Horns...............that stuff is for the theater!

    Thank YOU guys!

    You are most kind [:$] Tonight, I decided to try one of my Telarc CDs that I have not played since I moved to my new home here. In this large raised ranch, the music room (where the K'Horns live) is under the kitchen and formal dining room. This CD is of organ and orchestra, both Rhineberger and Dupre' at the Royal Albert Hall - Michael Murray at the console... Rich and full. At about the 10:00 O'clock position on my Marantz (about 15 watts per channel), the kitchen stove burners were buzzing like hell, and the 32' pedal was giving a foot massage from the stone tiled floor underfoot! IMPRESSIVE! Who would have ever thought that this much bass could be had LONG before subwoofers came into existence?!???? This with only ONE K'Horn loading the corner walls!! Can't wait to get the left channel wall built!

    I'm loving this `new' sound of HORNS !! Back in the early days, I disliked ANYTHING that was horn loaded, It sounded harsh to my ears, but I'm not feeling that way anymore, maturing ears perhaps?? [:)]


    Keep the replies coming!

    Here then is the FINAL photo of my project. In short, the NEW caps on the XOVER, the new K-55-V diaphragms with new seals installed. The new Crites CT-125 tweeters. The improvements are incredible! I now have crystal clear highs, clean NON buzzing midrange and the sound stage is so improved !!

    I am VERY pleased with what I am hearing so far, and this with an old SS Marantz integrated amp (4140) running 25 wpc mode.. I will try my ADCOM with the Marantz as a preamp next. Then. later start a new project with restoring FOUR Dynaco MK III amps.

    Thanks for viewing and please feel free to comment, critique or what ever [;)]


    Kind regards to all,

    Gary

    THIS is an IMPORTANT detail that must be mentioned. ATTENTION Bob Crites.. The mounting holes on the CT-125 are indeed the same as the original K-77 in location, HOWEVER, the holes on the horn flange are too SMALL, at least to mate with the threaded hardware on my K'Horns. So, if this is the case for you, I used a 1/4" drill to match the original sized holes, drilled and then went ahead and mounted the new tweeters without a problem...
