Hinges

Hello folks, I am looking to re-build/re-work my old stereo cabinet for my new theater room. I have an old O'sullivan AR-177 stereo cabinet that has served me well for over 25 years. I now wish to rebuild it as a lower, double wide unit for my current hardware. What I am needing is more of the spring loaded, rear, glass top hinges. I have three from my current unit but am looking for 3 to 5 additional hinges for my new design.............................. .................................................................................................................... I also hope to find a supplier for the glass cover lift edge. That is the 90 degree frame piece which allows the glass top and glass front to form an enclosure for the top located turntable and/or the tube amp. I have posted pictures of what I am looking for at: ................................. .................................................................................................................. neandertal.imgur.com (May yet be able to post them here if I can figure it out.) ................................ ................................................................................................................... If I can not match these exact pieces, does anyone know of a source that can provide similar functioning units? I am intending to build a cabinet which is "double" wide and will allow me an opening turntable top on one side and an opening cover for the tube amp on the other side. Any help to guide me to these pieces would be greatly appreciated. ................................................................................................ I am finally able to build my long desired theater room and I am planning to build a new hardware cabinet with the veneer matching my speakers. Will take several months of work and I would be happy to share the progress if any are interested......................................... Thanks, Bert

Also, I need to add I do not know who did the PDF drawings. I work in AutoCad and the drawings I posted were as jpgs. The first ones inserted in this thread are the ones I drew. I also would appreciate a zip of all the data that has been collected for the Jubilee in case I have missed something. Bert

Hello, I am "neandertal" and the drawings for the Jubilee are mine. I was working on reverse engineering the best match to Paul's dream of the "best" possible Klipsch speaker. I used the input from all members who had any exposure to the Jubilee prototypes or any possible suggestions. I (we) produced the design drawings from a composite of ideas. The well dried up and no further suggestions resulted in the project dying before we completed the whole package. The base bin was fairly well resolved but we never did come up with a hardware list or any cross-over ideas. I will have a set built by the end of the year to prove-up all the assumptions made in the design process. I will be glad to continue work on a final set of drawings if we find a renewed interest. Bert

Hello again folks, I hope we are not yet finished with this effort. No response, ideas, or input for a few days. Have we hit a brick wall or are you folks doing "detailed research" and will provide outstanding data for us to bask in? Anyone close to Hope, Arkansas that could visit Mrs. PKW and research (spy) on the Jubille? Trey.....any offer of helping us? Any "formal" response at all from Klipsch Audio Technologies? Trey...does Klipsch WANT to sell the LF bin to the general public in any volume? Anyone want to discuss the driver hardware? Network ideas? I will produce drawings of the board cuts (including angles) after it becomes obvious that no changes will be made to the "final" design. Bert

Hello again, Gil...I patent searched the following names and words: Klipsch Klipsch, Associates Delgado (co-author on the Jubilee paper, Delgado was noted in patent #5,000,286; "Modular Loundpseaker Design") Hope, Arkansas and a few others If the Jubilee is patented in any form it would not have been by PKW, Delgado, Klipsch and Associates, Klipsch Audio Technologies, or any combo of the Klipsch name.

Here is the motor board in it's most simple form. No drone and the drivers centered. Easy and well balanced but does cut the A-B throat distance to a value less than that of the reference numbers. Bert

Here is the motor board with a 12" drone. This is a work in progress. I still do not have a good idea of what the drone is doing. Need your imput folks. Bert

Current (April 4) plan veiw of the LF bin. This is the design using the 5"x9" driver slots in the motor board. Does this look like what you folks believe it should appear? Bert

An open answer as to what I am trying to achieve with this design effort. A few points are: 1) Attached is a drawing of what I believe may be the greatest benefit of an avaliable Jubilee for the unwashed masses. The beast need not be perfectly fit into a 4' deeep corner to work. The attached drawing shows how if would be easier to use than a Khorn for the same (better?) sound. Khorn quality sound without the need for corners....i'm interested. 2) I would like to generate a set of plans for THE speaker Paul was interested enough in to spend his retirement days designing. This would be the 2-way design with a drone in the LF bin. 3) A 2-way design without the drone in the LF bin This would be the bin currntly available from Klipsch but we would also have the data of the HF horn and 2 way crossover. 4) A 3-way design with or without the drone in the LF bin. I have a personal interest in a 3-way design using the best LF bin design we can come up with and the squawker/tweeter upper combo from a Heresy to top it out (the Jubilee bin would allow a 700hz crossover and hence a K-700 horn from the Heresy). This would give me Khorn that I could use on the wall in which I lack the proper corner for a Khorn and have a best tone match with my Heresy surround speakers in a 5.1 setup. Maybe not a purest intent...but one which best matches may current needs. 5) Any other combo any of you may have a need for. P.S. Anyone inform as to how I may place a drawing in the text? Thanks, Bert

Hello again, I have been working on the drawings this weekend and have several updates that will follow. I would first like to address Trey's comments. 1) This effort is for D.I.Y. usage. I have no intend to build and sell any speakers. I also do not have any interest in is selling a drawing set (this is a group effort in an open forum). This project is to educate ourselves in what may be the best home sized speaker Paul Klipsch ever designed. Since it has been made very clear that Klipsch Inc. will not build them....let us who have the some skill and time try to best honor the man and the design which Paul worked on as his last/best effort. He had a need to design it....some of us have a need to hear it. 2) I have searched and do not find a patent on the "Jubilee" design. I checked back to 1978 and find only 4 patents awarded to Paul between 1978 and his death: #4,138,594 The LB-78 speaker (Little Bastard) #4,210,223 Low-freguancy folded horn (Looks to be the commercial KPT-MWM prototype) #4,237,340 Crossover network for the "Little Bastard" #4,387,786 Anechoic Chamber Arrangement 3) I am aware Klipsch is selling the commercial LF bin from the Jubilee. What we would like to see is the design that does include the drone (for home use) as may be considered to be the "ultimate" Klipsch speaker. Also need to see if we can develope the two-way design by determining the HF horn design and network details. Maybe we can help generate a sales market for the available LF bin if we could match it with the remainder of the Jubilee design for home use. 4) Trey...any offer of data from your end to support what is an attempt to promote the legacy of Paul Klipsch? As noted above....maybe we can help you sell a few more LF bins without cutting Klipsch out of sales of a speaker you admitt won't be sold. Bert

Hello again, I have read, I have thought, I have calculated. Here is how it MAY be with regard to the slot opening at point A. PKW's design data has the throat at .029 sq.m. The .pdf drawing measures the opening at 4.916" so lets bump it to an even 5" (the pdf drawing has been pretty darn accurate so far). The resulting half throat created by the splitter is 2.5" which is the same as the A-B flare width. This would also meet D-man's comments about having the slot opening match the following flare width. Also matches the concept of the splitter acting as a two sided reflector. With the Point A throat at .029 sq.m (for BOTH the upper and lower drivers combined...all the other measured throats have been combined numbers) which equals 44.95 sq.in. and a width of 5"....the height would be 8.99" or just about 9" if we are a touch sloppy when the slot is cut. So we now have a 5" by 9" slot split into two halves and doubled by having two drivers. Now to the A-B flare length. By making the slot wider....the length shortens because it is measured from the center of the bifricated(sp?) slot at point A. I now calculate this to be 7.436" or .189m horizontal. We are short from the PKW design of .209m. Now remember this is in the horizontal plane. Now follow into 3-D. With the assumed LF bin at 38" tall (PKW's number)...the interior motorboard is going to be 36.5" tall. Asigning 12" to the center drone, this leaves an upper and lower 12-1/4" for the drivers. Centering a 5"x9" slot in this area gives us a Point A which is 6-1/8" from the top and bottom of the motor board. Each driver's horn is at 18-1/4" wide (2x 18.25" = 36.5"). The CENTER of EACH horn is 9-1/8" from the top or bottom. The VERTICAL distance between the 1/2 slot A CENTER and the center path of an individual horn is 3". Now to geometry...the horizontal path is 7.436" and the vertical is 3"....the linear path is 8.018" or .204 m. This does compare well to PKW's design value of .209 m. I will draw this up if the majority agree this is a sound path to follow. Once the horn flare passes Point B the two individual half horns are full height in the body of the LF bin. These assumptions will have the A-B flare being built with asymetrical(sp?) wings. Still need to know if the drone opens in any shape or form into the horn path. Any quesses as to how that thing works? Anyone have a clue as to what drone is used? Will draw more soon. Keep feeding me ideas. Bert
