chrapladm Posted February 23, 2011 Share Posted February 23, 2011 WOW......I have the Jamboree plans and wont be building them yet. I just dont have the room for them in my living room.[]yet. But its great to see someone else building these so I can learn what to expect. Greg from Volti makes evereything look so easy. I am very much the amatuer so I like seeing others builds to help me. What is a Kreg jig or whatever it is called? And was the tenun jig hard to make? I have never used one so I wouldn't have a clue. Quote Link to comment Share on other sites More sharing options...

Nat Denkin Posted February 24, 2011 Author Share Posted February 24, 2011 I guess you will need to get the grills on the cabinets rather quickly, since now that your wife chose the veneer, she may be getting ready to ask “when will you get those mirrors inlayed so she can actually set up all those figurines?” Nice work, they look great! You are so right! One visitor asked why I didn't extend the "bookshelves" all the way across. I am still deciding how to finish the grills. I might want to trim them with wood finished to match the mi-range horns. Of course, another approach would be to leave the Jamborees open. Mirrors might make them appear too busy [], but I wondered how that would look. Not too bad? Quote Link to comment Share on other sites More sharing options...
Nat Denkin Posted February 24, 2011 Author Share Posted February 24, 2011 Nice work on the speakers. Your wife is a real princess going along with that! I have been putting down hardwood flooring in my house. I'm looking for what to buy for the kitchen next. Is that maple Bogart is laying on? It has a nice look to it. I need to remember how supportive my wife is; sometimes I forget. I work slowly so the mess was there for several months. The floor under Bogart is red oak. The planks are actually a laminate with something like an 1/8th inch of red oak bonded to some engineered wood that could be directly bonded to the cement slab. Our heating is thru the slab so the flooring has to deal with being hot part of the year. Upstairs we do have 3/4 inch red oak hard wood floors that I put in my self. I enjoyed that job so much that I keep the stapler out as a reminder. Quote Link to comment Share on other sites More sharing options...

What is a Kreg jig or whatever it is called? And was the tenun jig hard to make? I have never used one so I wouldn't have a clue. While the Jamborees are a little larger than Klipschorns, the enclosed bass horns allows them to be away from the corners. Having the right tools certainly makes the job easier, but for the most part I got by with a small table saw, a sliding mitre saw, router, and lots of planning. There are some typos in the plans so you should draw it out full scale and building the entire project before glueing is highly recommended. Some of the pieces were challenging for me and the photographs above were intended to show how those pieces could be made. In the end, it was actually easier than I expected to make the pieces. I did talk with Greg Roberts about the Jamborees and he did the veneered panels I mounted on the front of Jamborees to match the Lavera Horns that are on top. Although I have built tractrix horns, they looked like I built them. Part of the deal for the entire project was that the finished product needed to look great as well as sound wonderful. Greg is wonderful to work with and was willing to customize his V-Trac horn to a lower cutoff and veneer it so the horn could be the center of attention and not merely hidden behind some grill cloth. After 26 years of looking at the clones I built before I met her, my wife is pleased by the results The Kreg Jig allows you to drill a counter sunk pocket hole in one piece and use Kreg's self tapping screws to solidly attach to another piece. While the holes can be plugged with matching or contrasting wood, with some planning, most of the holes are not visible. Kreg also has clamps that make it easier to hold the pieces together. Since the screws are self tapping, alignment of the pieces is easier. The local Lowes carries the Jig and other piece parts but an even larger selection can be found by googling Kreg Jig. I also bought a small electric screwdriver with a 90 degree attachment to get into tight places where a driver with a long bit simply won't fit. My table saw has 5/8 inch grooves so that standard tenon jigs (which required 3/4 inch grooves) would not fit. I built a jig that fit over the fence. Iit was too loose so I was able to use a cardboard shim to keep it tight. Had I planned it that way, I would have used something like teflon to make it slide easily. The jig was big enough to hold the wood securely with clamps so that I merely had to push the jig through the saw. I replaced the saw guard with clamped guards of wood to avoid having an exposed saw blade. That scene at the begining of "I Walk the Line" is sobering so I spent a lot of time thinking about safety. Whenever I did something stupid...like a wrong measurement, I stopped what I was doing and took a long break...often to the next day. It's not so much that I wanted perfection, but rather, I thought if I were making mistakes, an accident was waiting to happen. Making test cuts and lots of jigs helps to be accurate. I do not have much experience in woodworking. When I built the clones, I worked with three other guys who had more experience. This time I was on my own. I am very pleased with the results. The sound is excellent. Quote Link to comment Share on other sites More sharing options...
chrapladm Posted February 24, 2011 Share Posted February 24, 2011 Well they look amazing. I will have to build these someday. I have always been a bit of a bass head although I do like sound quality, I love to feel the music. I have the Kunzel Telarc recording of the 1812 overture with live canon blasts. And although the Jamboree doesn't go as low as the canon blasts do I was hoping that you would get the feeling you were right next to the canons when they played. I will have to see what you think of the Jamborees and see if you think they do the canon sound justice. I figured four 15's is alot of energy and in a horn that should really have a blast. But I will wait to hear your opinion. What did you use for powering the Jamboree and the horn? Quote Link to comment Share on other sites More sharing options...

But I will wait to hear your opinion. What did you use for powering the Jamboree and the horn? I just listened to the Kunzel Telarc and even with the Jamborees still on the dollies, you can feel the canon shots go right through your gut. I liked the Bob Crites CW1526C 15" woofers on my Khorn clones. Putting a pair of them in each Jamboree was one of my goals. The RTA showed that the CD was putting out uniform power from 20Hz to beyond 400Hz with each canon shot. The Jamborees probably are getting into the mid 30Hz region. Keep in mind that the horn mouth is not much larger than in the Klipschorn. I am tri-amping the drivers with Crown D-75A for the woofers which are wired in parallel. I am guessing that the Jamboree sensitivity is something like 107 dB so the Crown is more than adequate. I use another Crown D-75A for the BMS4592 midrange drivers and a Crown D-45 for the Beyma CP-25 tweeters. The woofers and midrange can handle anything the amplifers put out while the D-45 merely puts out 25 watts at 0.1% THD so I am not worried about frying the drivers and use nothing but wire (14 gauge) between the amps and drivers. A modified Behringer DCX2496 provides the digital active crossover and volume control. I am currently using a design by Le Cleac'h that varies the time delay correction and uses 18 dB/cotave Butterworth filters crossed at -5dB to provide less phase shift than you can get with passive filters. If you are interested in percussion, I think you can hear better imaging when the phase is not ignored. Any speaker you build yourself will sound better. When I finish the grills and fill in all the pockets I will put the speakers on the floor and measure the response. I know I have lots of room resonances so I may experiment with some base traps before I am done. The trouble is, I spend too much time listening to the speakers that I have little time to finish them! Quote Link to comment Share on other sites More sharing options...
chrapladm Posted February 27, 2011 Share Posted February 27, 2011 I need to check out that modded 2496. I have seen tube mods but dont really understand all the mods. So I will do a search for your mod and see what I can find. And I keep seeing these Crown amps that alot of others are using on this forum. I wont be able to buy them but can dream. Maybe a T-amp I can build. The Crowns I keep seeing are around $900 so that might be my weakest link after building them. Well that and may 13.5ft width room that they would have to go against.[] Quote Link to comment Share on other sites More sharing options...

I am using the Jan Didden mod described in http://www.linearaudio.nl/6chan-1.htm. It replaces the I/O stages completely and adds a 6-channel volume control and independent control of two new analog input stages. Also included is the ability to remote control the mod. I use a Logitech univeral controller to control the mod and also my CD player. I am also using itunes to store my CDs in Apple lossless format to play directly from my computer. I haven't figured out how to control itunes remotely. I have ordered another mod designed by Frank Oettle that improves the SRC and clock. The Crown D-series amps are frequently available on e-bay.which is where I got mine. The only concern I have about them is the power transformers can have a slight hum (which is hard to hear even in a quiet room unless you get close to them) . Depending on your patience, the price can vary. I got mine over the range $135 to $240 plus shipping. Sometimes a bunch come on at the same time and depress the price. Crown provides excellent support on line. The DCX2496 is popular for modding because it is relativly inexpensive and easy to mod. The analog circuits are frequently replaced and among the replacements you will also find tube amplifiers and transformers. There are lots of T-amps, class-D amps, and kits available, and it is often satisfying to built your own. While I would certainly recommend the components I used, there are many others discussed on this forum that fit a variety of budgets and that have been independently measured. My room is 13 foot wide except for a part that adds another three feet. The back of the room is open to a hallway so it is hard to define the length. At one time (long ago) I measured the bass response and found large variations because of standing waves. Some day, I might get around to trying some DIY bass traps and see if I can hear a difference. Enjoy the journey! Quote Link to comment Share on other sites More sharing options...
chrapladm Posted February 27, 2011 Share Posted February 27, 2011 Do you have any pics of the speakers(Jambs) across the living room? Just wondering how they look in the living room. I know you showed the one in the corner but I didn't know if you had any full living room pics? Or maybe not because there is still construction going on? Either way thanks for the helpful info and build thread. Quote Link to comment Share on other sites More sharing options...
Samhinh Posted August 31, 2015 Share Posted August 31, 2015 I am from vietnam. I ve just asked dana moore for jamboree plan. Please help me, this caninet can be used with my 2 bass jbl 130a? Thank all, 1 Quote Link to comment Share on other sites More sharing options...
Marvel Posted September 1, 2015 Share Posted September 1, 2015 (edited) There are two woofers in each cabinet. If you only have two 15" woofers, you could ask him about his SL6 cabinet, which uses reflex ports (which vent into the horn). Response down into the mid to low 30s depending on the drivers. The SL6 is also an easier build Bruce Edited September 1, 2015 by Marvel 1 Quote Link to comment Share on other sites More sharing options...
