Daddy Dee Posted December 13, 2012 Share Posted December 13, 2012 Peter, whoa. that speakers looks awesome. What's inside? Any more pics? Trying to get a sense of scale. Does a 15" woofer live in there? Quote Link to comment Share on other sites More sharing options...
pzannucci Posted December 13, 2012 Share Posted December 13, 2012 Peter, whoa. that speakers looks awesome. What's inside? Any more pics? Trying to get a sense of scale. Does a 15" woofer live in there? Those were to be the last speakers I needed to build to offset my K-horns which I finally sold to a forum member. They have 2 KLF-20 woofers in a 6 cf enclosure, 2 Focal Audiom 6WM mids and Aurum Cantus G1 ribbon. 24db high mid crossovers @1800hz using ribbon inductors and 12db @ 300hz crossover for the woofers. mid-treble smooth as silk, 2 KLF-20 woofers in each for the bass can move some air tuned to around 32hz in a big enclosure. Someday I might tear at my KLF-30's and take the woofers for the bottom end so I can squeeze more efficiency out of them. This used to be my mess: Quote Link to comment Share on other sites More sharing options...
Tin Turtle Posted December 14, 2012 Author Share Posted December 14, 2012 You need to help me out with the "h bracing". What are you describing? A link where I can read up is good too -- not trying to be lazy just need some guidance. BTW.. new upgrade today.... Anthem MRX-500 to serve as a pre and drive the surround and center channels when I get them built next year. Quote Link to comment Share on other sites More sharing options...
garyeanderson Posted December 14, 2012 Share Posted December 14, 2012 Your workmanship looks great. I enjoy seeing what otherscome up with in their quest to have what they desire. I built some heavyweightlascala clone bass bins that weigh about 155 lbs. empty. They get slid onthe floor if I need to move them. My back hurts thinking about moving anythingmore. The next pair of bins (actually 2 pair, second pair only had one devide brace) I built was a bit lighter and wascornwall clone bass bins and wereless than half the weight at 75 lbs for the empty bass bin but were stillpretty well braced. I don’t know if it will help you or not The write up I didis located here. http://forums.klipsch.com/forums/p/147639/1519463.aspx#1519463 I am looking forward to seeing your completed speakers.

pzannucci Posted December 14, 2012 Share Posted December 14, 2012 Sorry didn't mean to derail anything here. Gary that is an excellent picture. When the sides back and front are tied together at multiple points, the box becomes significantly more solid. Multiples as in the picture make the large panels smaller making them less likely to vibrate. The box should not go boing when hit with your hand but should have a very dull thud. Less overhang and much tighter bass. Extending the supports to the bottom would be good also but less valuable. The top support would be a little more usable. The supports will also get rid of the woody tone that you can even hear with k-horns when up louder due to the large panels. Wish I had taken pictures during several of my builds. The mid / treble section on mine are double sided 1.5" thick and H-braced. The thick sides and bracing make for seemingly faster more articulate sound. Two caveats are that you have to make sure you have the right volume for the interior and don't get a hernia moving the speakers as large as yours.

Tin Turtle Posted December 14, 2012 Author Share Posted December 14, 2012 Awesome, thanks for the pictures. I will look at bracing some more, I do not have a volume problem, in fact I am at the upper threshold, so additional bracing will not hurt me. I was thinking since my cabinets are smaller (19.5" inside height) that the sides would be ok with minimal bracing. I will take some more pictures today. Plus I have to deal with the driver issue and what kind of room I have once they are mounted. They will weigh a ton anyway, so a few pounds more is not a big deal.

Tin Turtle Posted December 16, 2012 Author Share Posted December 16, 2012 I have a space issue because these things are monsters. In order for everything to fit, I need to eliminate my rack. I can fit two pieces under the tv for now, but I need to be able to fit two pieces to the side. I was digging around the wood rack and found two pieces of heavily figured cherry and walnut that I have had for 6 years or more. This seemed like a good time to use them, and build something to match the Cornscala's. Here's a pic of the cherry rough sawn. Cool figure, but a lot of minerals. I had an idea about what I wanted, and to really work with the curl I like to use hand tools. I broke out the block plane and spoke shave to carve me out a set of legs. Then the panels were laid up and hand scraped. I lost a full day blowing up one of the motor boards for the upper cab. All the way to the final milling op, and I took a chance that cost me the entire piece. I wanted to shoot the Cornscala tomorrow, but now there is no way. I have to say the texture on the side panels is excellent. Now I just have to recreate it for the motorboards. Quote Link to comment Share on other sites More sharing options...

Tin Turtle Posted December 16, 2012 Author Share Posted December 16, 2012 Tin Turtle - beautiful work. How do you have the patience to do that. I start a build and I am anxious to be done the next day I hear you, it has been a month or so since I blew up my JBL's No music, no decent movies and a new Anthem MX500 that I have never heard. I am going crazy, but at this point I feel like a few more days is worth it to get something cool. The funny thing is hand tools save a lot of time. Thats why I built the shop, I always wanted to be an old school American furniture maker in the method sense, but style wise I like anything.

Tin Turtle Posted December 16, 2012 Author Share Posted December 16, 2012 I finished everything the lower cabs needed to be ready for laquer tomorrow. The footer is attached, the motorboard is in place and the seperator/brace is screwed to the top. The backs were put in place and the hardwood batting predrilled for #6 brass screws. They will get sanded down later to prep for tomorrow. The ubiquitous Bigbys Pour House glass is primed with a Southern Tier Creme Brulee just below freezing. http://www.tinturtle.com/image.axd?picture=2012%2f12%2fbasscab_readytospray.jpg http://www.tinturtle.com/image.axd?picture=2012%2f12%2fbasscab_backs.jpg Quote Link to comment Share on other sites More sharing options...

Tin Turtle Posted December 17, 2012 Author Share Posted December 17, 2012 Here are a few more pictures from this evening. The first shows the bottom and how it overlaps the **** joint on the lower part of the cabinet. This helps reinforce that joint that is holding all the weight of everything above it. http://www.tinturtle.com/image.axd?picture=2012%2f12%2ffooter_feet.jpg Then a picture of the front of the upper cab with the textured side panels in place. This shows how far back the panels extend to reinforce those vertical walls. http://www.tinturtle.com/image.axd?picture=2012%2f12%2fuppercab_sidepanels.jpg Then a shot of the final bit of work this evening. I took the spare motorboard that I blew up with the router and used it to test fit the horn. Now I can build the support in the back to hold that driver. http://www.tinturtle.com/image.axd?picture=2012%2f12%2fuppercab_horntest.jpg Quote Link to comment Share on other sites More sharing options...

Tin Turtle Posted December 18, 2012 Author Share Posted December 18, 2012 Finished installing the motorboards in the upper cabinets, added reinforcement to the tops and the brace supports are in. After they get sprayed I will put in the braces. The dampening is done for these, and they are ready to spray. I will be glad when these are done. http://www.tinturtle.com/image.axd?picture=2012%2f12%2fuppercab_prespray1.jpg http://www.tinturtle.com/image.axd?picture=2012%2f12%2fuppercab_top.jpg http://www.tinturtle.com/image.axd?picture=2012%2f12%2fuppercab_dampening.jpg Quote Link to comment Share on other sites More sharing options...
Tin Turtle Posted December 20, 2012 Author Share Posted December 20, 2012 I just finished the final spray on the speakers and they will be ready for assembly tomorrow. I am excited to hear them. The finish went down really, really well and it was the first time I used the Chemcraft Varicure product. It is freakishly durable to everything, household chemicals, 409 - whatever. The guys over at Chicagoland Finishing Materialswere a huge help and really know their stuff. The order of finish was: 1) 1 coat of boiled linseed oil (hand rubbed)2) 3 coats of General Finishes Arm-R-Seal (hand rubbed and then cured for 1 week). Sand with 320 and then 400.3) 1 coat of Chemcraft Variseal. Sand with 400.4) 2 coats of Chemcraft Varicure Satin. Sand with 600 before final coat. http://www.tinturtle.com/image.axd?picture=2012%2f12%2ftopsfinalspray.jpg The mini audio stand for the two components is done too. Curly cherry and walnut, and walnut pins for the bottom shelf. The bottom shelf will hold my Hafler 9303 Transnova amp, so it needed to be a bit sturdier. The order of finish was: 1) 1 coat of tung oil (hand rubbed and cured for 48 hours)2) 1 coat of Chemcraft Variseal3) 2 coats of Chemcraft Varicure Satin Everything will get rubbed out with a coat of Renaissance Wax tomorrow after it cures out. http://www.tinturtle.com/image.axd?picture=2012%2f12%2fminiaudiostand.jpg Quote Link to comment Share on other sites More sharing options...

Tin Turtle Posted December 22, 2012 Author Share Posted December 22, 2012 Ok, they are assembled, in place and being broke in. I still need to build grills, but for now this is how they set. I will do a more detailed writeup to finish this thread off when I have that done, and I have had some time to listen to them. The detail is really good, but I need to listen to them across a wide variety of recordings. http://www.tinturtle.com/image.axd?picture=2012%2f12%2fAssembled_NoGrill_AllFront_.jpg http://www.tinturtle.com/image.axd?picture=2012%2f12%2fAssembled_NoGrill_SideView_.jpg The brass screws are really a nice touch. The speakers have this old school, vintage look that I have come to like, but they will still tear your face off. I started out with Etta James - Love Songs and the detail is really amazing, so much that I was startled. And a quick listen to Black Sabbath - Hole in the Sky was a lot of fun. I will say this - I have all the volume I will ever need. http://www.tinturtle.com/image.axd?picture=2012%2f12%2fAssembled_NoGrill_Back_smal.jpg And the little audio rack came out pretty nice too. http://www.tinturtle.com/image.axd?picture=2012%2f12%2fAssembled_MiniAudioRack_sma.jpg Quote Link to comment Share on other sites More sharing options...
