colterphoto1 Posted December 16, 2008 Share Posted December 16, 2008 The tool that makes the K701 horn is very very old. The tool for the K601 Cornwall horn is lost. I doubt if they'll go to the expense of making new tooling. It's very expensive. For now I think they're painting the horns but there is some pitting and slag in them from the molding process. They looked a lot different back in the day. When you bolt up the driver and install in the cabinet there's usually so little light that you can't see anything anyway.

CECAA850 Posted December 17, 2008 Share Posted December 17, 2008 K-107-Ti Tweeter Bob How can you tell polarity? Mine have the same size lugs and I can't find any marks on either side. Quote Link to comment Share on other sites More sharing options...
BEC Posted December 17, 2008 Author Share Posted December 17, 2008 There is a "+" near the positive terminal. It is a bit hard to see, but I think I have this picture blown up to the point you can see it near the left terminal. Bob Quote Link to comment Share on other sites More sharing options...
Islander Posted December 17, 2008 Share Posted December 17, 2008 For the squawker driver, the instructions say to look for a sticker, a dot of paint, or a plus sign near the positive terminal. On my new driver, there was a paint stripe near one terminal, which of course looked like a minus sign. I took it to be a very wide dot of paint and connected the positive lead to it, with some doubt, but the speaker seems to sound fine. On the tweeter, there was a molded plus sign just as on Bob's example. Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted December 17, 2008 Share Posted December 17, 2008 Crossover inside the cabinet. This is where we notice that the wires are too short to reach the tweeter. Bob That is unacceptable. This just should not happen. Is there any issue in having a wire slightly too long in the cabinet? Whenever I wire anything (most recently pool pumps) I make sure that there is extra wire so that if trimming or a repair is ever necessary it can be done.

CECAA850 Posted December 18, 2008 Share Posted December 18, 2008 Thanks Bob, I believe I see it molded into the plastic? If so, I'm sure I overlooked it due to it's location up under the magnet. I appreciate the help. I didn't have any paint dots on mine. Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted December 18, 2008 Share Posted December 18, 2008 Carl (CECAA850) I wish I had known that new crossover cup assembly size before.... I would have cut the new cup hole with an inset to make it all prettyfied.... Oh well. BTW: Carl or Bob; what are the dimensions of that cup (outside edge and inside edge)?

CECAA850 Posted December 18, 2008 Share Posted December 18, 2008 I'm at work now, but if Bob doesn't chime in, I'll try to get a measurement tonight. Here's why I couldn't find the polarity on the tweeter. Quote Link to comment Share on other sites More sharing options...

Groomlakearea51 Posted December 18, 2008 Share Posted December 18, 2008 On page 3 of the thread Bob has a photo of the H-III vs the H-II. The H-III is longer and won't fit flush in the cutout. Bob installed some foam strip gasket material. If I knew the dimensions, I could modify the rear panels by enlarging the cout-out lengthways with a router allowing the H-III to fit "flush".

BEC Posted December 18, 2008 Author Share Posted December 18, 2008 H3 crossover is 5.1065 wide X 7 1/2 inches long. Bob Quote Link to comment Share on other sites More sharing options...
laager Posted December 25, 2008 Share Posted December 25, 2008 I think it's strange you should need to lengthen wires to reach the tweeter. I reassembled some H3s that Michael sent me and there was no issue. Mind you, I mounted everything to the motor board and reached in through the network hole to connect wires. Yes, it's blind but even a butter fingers can feel where the tangs are and get the spade connector over it. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted December 29, 2008 Share Posted December 29, 2008 Yes, it's blind but even a butter fingers can feel where the tangs are and get the spade connector over it. What did you do to check polarity on the tweeters? The spades ar the same size for + and -. Quote Link to comment Share on other sites More sharing options...
Deang Posted December 29, 2008 Share Posted December 29, 2008 Look for the factory mark on the driver itself -- sometimes just a slash with a marker on one side of the magnet or the other. Quote Link to comment Share on other sites More sharing options...

Granted, I was just wondering how he did it "blind" reaching into the speaker through the back with the drivers mounted. Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted December 29, 2008 Share Posted December 29, 2008 I'm at work now, but if Bob doesn't chime in, I'll try to get a measurement tonight. Here's why I couldn't find the polarity on the tweeter. Look on the other side of the plastic thingie with the two terminals on it. One side should be embossed +. Mine has a dab of white paint on that terminal on the top (motor board) side. From your photo, if it's the same as mine, the terminal to the LEFT (as viewed from the back with terminals facing down) is the POSITIVE Quote Link to comment Share on other sites More sharing options...

BEC Posted January 2, 2009 Author Share Posted January 2, 2009 A pleasant visit here at the Crites homestead today. Daddy Dee and Tony Reed showed up bearing Whataburgers, fries and rings. Entertainment was provided by the H1 vs H2 vs H3 and a bit of Cornscala mixed in on the side. Bob Crites Quote Link to comment Share on other sites More sharing options...
HDBRbuilder Posted January 3, 2009 Share Posted January 3, 2009 Bob, I kinda wondered if I showed up WITHOUT whataburgers, would my welcome and sonic listening pleasure consist of a double barrel 12 guage with rock salt and a finger pointing to the quickest way to exit the property??

kdcarroll Posted January 3, 2009 Share Posted January 3, 2009 Not to begin to actually contribute in any meaningful way; but I want to point out that Whattaburger in Russellville ought to have a steeple on top. Most churches do.When I went to Tech (just shortly after the earth's surface cooled), the ONLY food in town was the kindly faces at Whattaburger. In the day, you could get a "double-double", large fries and a shake in a glass big enough to hold Lake Dardanelle; all for the college friendly sum of about 5 bucks. I met my wife in line at Whattaburger, and had many meaningful dates there. Now, a billion years later, I have traveled all over the globe, and can say without fear of any dispute; that place is still the best. When I am lucky enough to have business take me within 60 miles of the place, I always detour. I have preached the "gospel" of Whatta so many times to my students that they arranged a pilgrimage this summer. They were quite disappointed when they arrived just at the beginning of the family vacation when the place closes for a week (where do people eat?). The place has changed - they have cool "new" indoor seats; but, most of the wall art is the same and many of the people working there are still familiar. What a great place and group of people in this cold, distant, "make a buck" world. All of you not having eaten there will die the poorer for the absence. I may get up and drive there tomorrow. Envy me! Quote Link to comment Share on other sites More sharing options...
