kevinmi Posted September 21, 2009 Share Posted September 21, 2009 I decided to finally re-do the Khorns. I used Crites Tweeters, Cast Woofers, and home built wood tratrix type mid horns. First pic of wood horn in the rough Quote Link to comment Share on other sites More sharing options...
kevinmi Posted September 21, 2009 Author Share Posted September 21, 2009 More wood horn with a dollop of polyester filler here and there. Quote Link to comment Share on other sites More sharing options...
kevinmi Posted September 21, 2009 Author Share Posted September 21, 2009 Used polyester filler (bondo) to make square throat round Quote Link to comment Share on other sites More sharing options...
kevinmi Posted September 21, 2009 Author Share Posted September 21, 2009 Coated all surfaces with fiberglass resin for rigidity, and then slopped black paint on 'em. Quote Link to comment Share on other sites More sharing options...
kevinmi Posted September 21, 2009 Author Share Posted September 21, 2009 Added adapters from Parts Express, installed Crites CT125 horns flush on front. Quote Link to comment Share on other sites More sharing options...
kevinmi Posted September 21, 2009 Author Share Posted September 21, 2009 Didn't have enough grill cloth to do sides like the original, so I used wood on the sides and just covered the front board. By the way, this is just a temporary setup, so it's not intended to be perfect. I'm going to build big horns with 2" drivers eventually.

kevinmi Posted September 21, 2009 Author Share Posted September 21, 2009 I decided to replace the diaphragms on the K55-V drivers while I had them out. Purchased from Bob Crites as well. Notice the wine glass--mandatory accessory for this kind of build-up! Quote Link to comment Share on other sites More sharing options...
kevinmi Posted September 21, 2009 Author Share Posted September 21, 2009 Next it's time to replace the woofers. Holy Crap, I enclosed the cabinets! (Note to myself: replace woofers first, then enclose, idiot!) Quote Link to comment Share on other sites More sharing options...

kevinmi Posted September 21, 2009 Author Share Posted September 21, 2009 May as well install 5 way binding posts while I'm hacking away. Bought from Parts Express with the sage advice from M Colter. Quote Link to comment Share on other sites More sharing options...
kevinmi Posted September 21, 2009 Author Share Posted September 21, 2009 Now for the interesting stuff: After hooking them up and giving them a listening to, I immediatly noticed improved bass response. I mean a bunch more bass! I attribute this to the mids/highs not blaring at me so loud and overwhelming the bass. The mids are so much more open, it's as if I can climb inside the horn and see the musicians playing. (Maybe a little too much wine!) I notice that I am playing the music at much louder volumes without listening fatique. Now I know that since I have all new drivers/diaphragms, that they need to be broken in before the sound they're best. Does anybody have a ball park idea of how long before they are broken in? Any good suggestions on the best method of breaking them in? About the mid horn-- horn dimensions are 8.25 by 16.5 inches, the biggest I could make with a 2:1 ratio and still fit the original height of the top hat. Many thanks to Mike Dubay for the program and answering many questions about using the program. Fc is 275, If I remember correctly. If anybody has suggestions on mid drivers I could try out with these horns, I'd appreciate the info. Also, I'm using AA crossovers with Crites Cap upgrade. Any suggestions/comments on crossover points or upgrades that would work with this setup? Any and all comments/suggestions/gripes/advice is greatly appreciated. Thanks-kevin Quote Link to comment Share on other sites More sharing options...
Guest David H Posted September 21, 2009 Share Posted September 21, 2009 Also, I'm using AA crossovers with Crites Cap upgrade. Any suggestions/comments on crossover points or upgrades that would work with this setup? You could alway build ALK universals, IMO they are a noticeable improvement. The side pieces an the grills were a nice improvise, I didn't notice til you mentioned it. Quote Link to comment Share on other sites More sharing options...
PrestonTom Posted September 21, 2009 Share Posted September 21, 2009 Kevin, That looks like a fun project. Congratulations! A comment about the bass being improved. Is it posible there were air leaks in the bass bin around the woofer access panel? In that case, when you remeoved then re-attached the access door ( I assume with a new gasket) then you may have gained a more air-tight bass bin. That can improve the low bass response. I only mention this as a possibility. -Tom Quote Link to comment Share on other sites More sharing options...

I can imagine the Crites woofers will kick it up a notch after they're broke in.-kevin Quote Link to comment Share on other sites More sharing options...
Invidiosulus Posted September 22, 2009 Share Posted September 22, 2009 Wow those look great. How does well do the highs disperse for you having the ct125 sideways like that? Quote Link to comment Share on other sites More sharing options...

I've actually read some posts that say the tweeters are supposed to be positioned this way.-kevin Quote Link to comment Share on other sites More sharing options...
