bigdnfay Posted January 28, 2005 Author Share Posted January 28, 2005 After I complete the two dimensional model I'll be able to get a more accurate set of drawings. Hopefully someone on the forum with a cad program would be willing help me out with it. Big D Quote Link to comment Share on other sites More sharing options...
Marvel Posted January 28, 2005 Share Posted January 28, 2005 I need to get a CAD program. I was playing with the free one from IMSI (TurboCAD), but every time I would zoom or come back from the day before, measurements would change. I just deleted it last night.

Klewless Posted January 28, 2005 Share Posted January 28, 2005 It seems like I read someplace on this forum that there was a 12" passive between the two driven cones. The passive was there to tune the chamber for about 5 Hz extension on the bottom. Three 12's plus some for boards gets you right close to the 39" khorn bass horn. I have no proof, just a cluttered dusty mind. I too have entertained rolling my own version to mate with an Altec 511B. Found some woofers I think would work but would rather have the ones Klipsch used. Think they would sell any? What woofers are you guys planning on using?

bigdnfay Posted January 28, 2005 Author Share Posted January 28, 2005 Klew, I too am planning to use a pair of 511b's collecting dust in my storage room. Having some trouble finding a good HF driver to mate with them. Any good suggestion? Did find a LF driver from pioneer with the right Qts but not crazy about the materials it's made with. klipsch uses the k-1080-kp in the commercial version.

bigdnfay Posted January 29, 2005 Author Share Posted January 29, 2005 My intent was to use Al's 2-3way ES700t extreme-slope network,but I have not discussed it with him to verify that it will work with this setup. I don't know the implications of using dual woofers. Thats better left to the experts. Big D Quote Link to comment Share on other sites More sharing options...
djk Posted January 29, 2005 Share Posted January 29, 2005 The JAES article gives the exact throat area Klipsch uses, and the back volume, and the area and length at three different points (it is not a constant taper). The Pioneer woofers have the same mass corner as the specified Klipsch drivers, and require the same back volume (even more important). Yeah, they are a cheap poly cone, but under $50 each. I probably wouldn't run more than 100W into them. A group buy could have the 'right' drivers made at Eminence. Quote Link to comment Share on other sites More sharing options...
Klewless Posted January 29, 2005 Share Posted January 29, 2005 Terry, I plan to cross at 500. Will look for the Altec 902 drivers. I have a pair or RCF drivers to try first (actually I have the horns for them also). I don't know anything about these drivers except that I made a ridiculos offer for them and ... Don't know which crossover to use. Quote Link to comment Share on other sites More sharing options...
Parrot Posted January 29, 2005 Share Posted January 29, 2005 Here is HDBRbuilder's post from 5/30/02: *************** RE: My Jubilee audition on Tuesday. Engineer Jim graciously interrupted his busy schedule to have a Jubilee set up for me to listen to. It was the same bass bin as the home version will be, but the high-end horn was fiberglass (or something similar), not wood. The bass bin was pushed by two 12" active drivers and one 12" passive radiator(drone). The listening format was MONO, not stereo. The amps were Crown. I first listened to whatever was in the CD player at the time, then changed over to some good ole Stevie Ray Vaughn. They sounded great!! And...they can get alot louder than what I heard, too. The listening room was the one up at the lab where others have heard them. The materials are fine veneers over MDF for the front and top panels...it appears the rest of the bass bin is plywood and wooden laminates. Underneath the grilles on each side of the bass bin are the exit ports of the folded horn...each port has "wing-shaped cross section" struts across them to provide structural support. Looking down into the bass bin, through the "door in the top" you see that it is lined with foam rubber at the rear, and from top to bottom you see one active 12" woofer, one 12" passive radiator in the middle, and one active 12" woofer at the bottom...all firing forward through chokes where the sound hits a vertical splitter sending the sound to each side instead of a horizontal splitter as on the k-horn, which sends the sound upwards and downwards. I was informed that the Jubilee drops only about 5 Hz lower than the k-horn specs, but its bass bin has much higher range...up to over 1000 Hz. This allows its crossover to begin around 800 Hz for the transition to the tweeter horn. I was also informed that the Jubilee is not only more efficient than the k-horn (needs less power to operate it), but it can handle over 600 watts per channel!! So...that leaves it as quite an improvement over the k-horn in its power range!! I was allowed to check out the interior of the bass bins on not only the home version, but some of the earlier prototypes. The original prototype versions had just the two 12" woofers powering them, but a 12" passive radiator(drone) was added to the final version for the home. Unlike the k-horn that fires forward, then splits into two horns, one firing over the top and one firing underneath of the "pyramid" towards the tailpiece where the directivity is rotated 90 degrees to follow the walls and floor,....the Jubilee fires forward, splitting and running around both SIDES, towards the rear where it apparently crosses and runs forward in its own built-in horn around the opposite sides from its starting point, and again runs forward out each side of the front of the bass bin. This allows it to be placed in a corner or along a wall. As a matter of fact, it performs better if it IS NOT snugged into a corner but is set out from the corner a particular distance...just as any other NON-CORNER HORN works!!! It seems that the Jubilee home version may well not be produced with a wooden tweeter horn due to cost of those horns to the company...consistancy of quality control for wooden tweeter horns is also a consideration...as is varying density in the wood used...anybody who knows wood realizes that two boards from the same tree can have very different densities!!...but that is all still up in the air at this point in time. Suffice it to say that the home version Jubilee has a footprint not very much smaller than a k-horn, but is considerably shorter in height. PWK's design parameters of the Jubilee: 1. More efficient than the k-horn. Parameter met! 2. Frequency range of bass bin both lower and higher than a k-horn. Parameter met! 3. Frequency range high enough for bass bin that it can be produced as a two-way system instead of a three-way system. Parameter met! 4. Smaller than a k-horn. Parameter met! 5. Doesn't have to be in a corner like a k-horn. Parameter met! 6. Even though more efficient and requiring less power, can handle much more power than a k-horn. Parameter met! 7. Sonic accuracy of a k-horn. Parameter met! When will they go into production? Sometime in the near future for the home version...the theater version (which is a three-way system) is already in production! The delay in the production of the home version is apparantly due to the decisions about the tweeter horn and some of the other little things such as shiny parts on top...LOL! Either way...the company wants to get them into production fairly soon!!! Price for a PAIR of the home Jubilees???...somewhere in the $15,000 range...soooooooo...better start saving up your aluminum beer cans for money at the recycling centers RIGHT NOW, if you want em!!!! ******************* Quote Link to comment Share on other sites More sharing options...
Parrot Posted January 29, 2005 Share Posted January 29, 2005 And from 1/17/03, this excerpt from HDBRbuilder: **************** 8. The plans for the home-version Jubilee when I saw it were to incorporate a vertically adjustable arcing device for the tweeter horn...IOW...you could adjust its aim up and down somewhat...using screw-wheel adjusters at the rear of the mounting of it...and all of this VISIBLE hardware was/is? planned to be gold anodized, etc...for aesthetic reasons...the center finely veneered panel was also designed to be removable and replaceable...so that one could adapt the speaker to changing decor of the room over time....whereas the Klipschorn is "what you see is what you get"!: aesthetic versatility matchpoint, Jubilee! ****************** Quote Link to comment Share on other sites More sharing options...
Klipsch Employees Trey Cannon Posted January 29, 2005 Klipsch Employees Share Posted January 29, 2005 we use a 3" TI compresion driver from B&C. I know that Roy and PWK tried many ways to make that last turn...I was there when the first few prototypes were built. Heck I have one...But I was to low in the food chain to get any real info. When using a passive it goes between the woofers. The ones the guys got to hear in Hope on the first "fan trip" used KLF-30 woofers. Did a fine job. The pro unit uses a 4" vc pro 12.

Parrot Posted January 29, 2005 Share Posted January 29, 2005 Trey, Was the "vertically adjustable arcing device for the tweeter horn" that Andy mentions ever actually built, or was it only sketched out? Quote Link to comment Share on other sites More sharing options...

Marvel Posted January 29, 2005 Share Posted January 29, 2005 Since it has more folds than an LS, how does it end up with more high end out of the bass section? Quote Link to comment Share on other sites More sharing options...
djk Posted January 29, 2005 Share Posted January 29, 2005 "Since it has more folds than an LS, how does it end up with more high end out of the bass section?" Mainly the reduced exit angle. "Yes, how WIDE is the throat, i.e., depth of the channel? It's somewhere around 2", I would think." The paper refers to a 0.029 m2 throat. The drawing > appears to show a > throat opening of 0.125 m (4.875"). This implies a > throat height of 0.235m > (9.375"). Quote Link to comment Share on other sites More sharing options...
