No major progress yet. I'm taking pictures along the way, so as soon as they start taking shape I will be sharing.

So now that I have a good idea of the components my next question is what Amps do people find work best with the KHorns? Lately, I have been looking at the Margules Arch-1.2, but I'm not entirely sure it is what I am looking for. It has jsut about everything I want (Triode, Tubes etc), but I'm not entirely convinced a hybrid is the way to go and I am also unsure I want to go with a strictly stereo amp. What's everyone using? What's out there? Thanks in advance... -Justin

Greg, Really appreciate reading all the first hand feedback. It's definitely incredibly helpful at this stage. You mentioned earlier in the thread that you're using the ALK universal network in your home khorns now. Out of curiosity, what was your impression of them vs the ES and A crossovers? -Justin

Right now I think that's pretty much the route I am going to take. I'm leaning towards the Bob Crites CT125 instead of the Beyma CP25 (anyone seen both in action ?) at the moment. Also, the plan right now is to build my own trachorns (did the cals and blueprints last weekend), but we will see if i stick to that plan. Glad to hear you're happy with the results, that give me a lot more confidence in my choices. -Justin

Bob, Glad to see you throwing your two cents into the mix. I am planning to get several of my componants from you, so yours is definitely an opinion I would like to have. My consern was that the specs sheets I read showed the exact oposite. Atlas lists the PD-5VH as topping out at 4100 Hz (listed 110 - 4,100 Hz via atlas), while the D250-X is 9000 Hz (400-9000 Hz via parts express). That is what led me to opt for the D250-X in lieu of the Atlas, in order to provide a nice overlap cussion. Again this is all based on spec sheets, so I am very interested in real world comparisons. Right now I am looking at the CW1526C and the CT125 for my top and bottom, with an upgraded crossover network, so I just want to be sure I have the right driver to fill that gap. -Justin

Honestly, my only real criteria is how easy it is to obtain new and how solid of a replacement it is. Right now I am just mapping the project out to get an idea of the direction I want to go. Once I have it mapped out a bit I am going to start on construction. Purchasing won't happen until I am most of the way done with the cabinet. I have head good things about the D250x ( and the $31 price tag is defintely a plus) with an in-line 10w resistor. Also, Bob Crites is listing the Atlas PD-5VH on his site as a direct K55v/x replacement but on paper the D250x seems like a much better option. Has anyone heard Ks with either of these in them?

Are there any good alternative horn drivers out there ? I am looking to use ALs universal crossovers in my project and would prefer not to have to adjust to accommodate a radically different driver. Any suggestions? -Justin

Greg, Thanks so much. That is eactly the info I was looking for. I would greatly appreciate a copy of the plans you mentioned and will shoot you an email in a moment. Let me know how the 2" driver on the Trachorn works out. -Justin

Tom Thanks for the info and the encouragement. Honestly, I haven't given much though to any alternatives to the khorn. They hold some sentimental value for me, so I am pretty locked on the course. I do fully realize that the project is no small undertaking, especially for a first time speaker builder, but I think I am up to the challenge. This is definitely a new arena for me but I was raised by a carpenter, and have a degree in EE, so I am well within my comfort zone. Thanks -Justin

I've wanted to build a pair of khorns since I was a kid and I have now reached a point in my life where i can actually do it. So, armed with a set of plans my father bought in the 60s I have started the research phase. Initially I was just going follow the plans to the letter and go as close to stock as possible, but I made the mistake of reading this fourm prior to setting off on my project . Now I'm looking to build the upgraded crossover networks from ALK along with an upgraded wood Trachorn (potentially ALK design as well). My problem is I am not entirely sure what horns/drivers etc to use. So far i've found a few tidbits here and there, but nothing substantial. So, my question is what are people's choice components for a khorn these days? This is going to be my first speaker building project, so i'm very curious to see what people think...
