hurdy_gurdyman Posted October 14, 2003 Share Posted October 14, 2003 How does one remove the driver from the horn on a heresy 1? It feels like it might be glued, but not sure. Dave Quote Link to comment Share on other sites More sharing options...

I put enough pressure on it that I was afraid of breaking it, but it wouldn't budge. I'd like to front mount the horn, butI need to remove the driver to do it. I suspect they may have been glued. If you're sure that glue wasn't used, I'll crank harder on them. Dave Quote Link to comment Share on other sites More sharing options...
dodger Posted October 15, 2003 Share Posted October 15, 2003 Hello: No glue was used, but since the time the horn was installed, some oxidation may have built up. That would contribute to the tightness. When you put it back together be careful not to cross-thread, then you're up the creek. dodger Quote Link to comment Share on other sites More sharing options...

The newer Heresy's seem to have solved the problem. I did a temporary fix by routing the wood slot to match the horn's flare, which made an audible difference. I plan to build a custom enclosure with a sub built into the bottom and front mount all the drivers. My origional enclosure is in very rough shape. You can see a pic of the modded Heresy here.

WMcD Posted October 15, 2003 Share Posted October 15, 2003 Try a spray of WD-40 in a way so that it can wick up into the threads and let it sit overnight, then give it another shot the next night. One trick with some screw in fittings is to give it a little torque in the forward, clockwise direction, and then rock it clockwise and counterclockwise. Maybe some can tell us if there is a rubber gasket which might interfere with penetration of the oil. In any event, you get the picture.

ricktate Posted October 16, 2003 Share Posted October 16, 2003 The newer Heresys were not front mounted for the flare of the horn,,,they are front mounted for productin speed,,,i still find it hard to believe it makes much difference.....but then some have said the same thing to me and Andy about grippers and HK430....so i guess if it sounds good do it....rick...ps you know you can front mount it without removing the driver...they did it on Heresys,cornwalls...its just got a half circle cut out on the hole, top and bottom just enough to get it through the slot Quote Link to comment Share on other sites More sharing options...
Malcolm Posted October 16, 2003 Share Posted October 16, 2003 There is a rubber gasket between the front of the K-55-V driver and the K-700 horn. But that will not affect how well a lubricant penetrates the threads. Quote Link to comment Share on other sites More sharing options...
JohnA Posted October 16, 2003 Share Posted October 16, 2003 DON'T remove the horn from a K-77/-M and reassemble it through the hole. I did it and was lucky (I think, they won't go over 14k). Reassembly through the hole makes it tough to align all the parts. Since you are building new cabinets, build the new ones with the top open like a Belle or La Scala, enlarge the tweeter hole, and buy the Klipsch Z-brackets made to flush mount the tweeter through a hole in 3/4" plywood. Until then, line the hole with felt. Quote Link to comment Share on other sites More sharing options...

Make sure there aren't bults holding the driver to the lense. If the lense is plastic (made around 1986) it is more than likly bolted on.

TBrennan Posted October 17, 2003 Share Posted October 17, 2003 Dave----The threads might be galled, the aluminum female threads of the horn combined with the steel male threads of the driver is a recipe for galling. You just need to use a little ***** on the thing. Once to remove the aluminum screw-on snout from a brand new JBL 2427 driver I had to put the snout in a large bench vice and turn the driver with a 36" pipe-wrench, I needed the 36" wrench. But off it came. Quote Link to comment Share on other sites More sharing options...

WMcD Posted October 17, 2003 Share Posted October 17, 2003 Yeah I was thinking this has something to do with the interaction between the steel and the aluminum. It might also help to put some rubber bands around the driver so you can get a better grip on it. As a last resort you can try a strap wrench. I see Bob Villa hawking them for Sears. When you put it back together some light grease or petoleum jelly is probably going to prevent the reoccurance. Gil Quote Link to comment Share on other sites More sharing options...

Malcolm Posted October 17, 2003 Share Posted October 17, 2003 Judicious application of heat, with a heat gun or even a hair drier, to the horn where it meets the squawker driver might help. Otherwise, I would suggest using a penetrating oil on the threads, clamping the horn carefully in a vice, and using a rubber strap wrench on the driver.
