Thanks colter. It looks like I may be out of luck getting much LF extension out of the K42's. I guess that I should rethink my design. Do you know where I can get the TS parameters? Another thought is using a pair of JBL 123A driver. That might not be the best thing to suggest around here. Thanks for the help. Kendal

I checked out the tags on the woofers and they are K42's. From what I have read this is a more robust woofer that was used in stage monitors and cinema speakers. The mid horn is a K59K. I haven't done any research on them yet. Where can I get the specs on the k 42 so I can better design the enclosure. I still want them to be a floorstand speaker about 40-42" tall. Thanks, Kendal

Well, I don't have one available, so I will have to experiment with what sounds best to me. I should be getting the tweeters in today, so I am going to do a test run in the front baffle that I have built. It won't be in a sealed enclosure, but it should give me an general idea about where I am going. The crossover from PE seems to be of average quality. More to come later. Boonaroo

If I was to use the existing crossover pulled from the cabinet, help me design a high freq. filter that I can integrate to the same board. Remember, I am a novice. I know that I can rewire the crossover to accept a single input, but from there I would be lost. Again, thanks for your help. Kendal

I am new to building speakers , but I am ready to give it my best effort. I have built furniture before and have access to a complete woodshop, so having proper equipment won't be a problem. So here is what I would like to try as my first speaker building project. I picked up a very good pair of Klipsch KMS stage monitors for a bargain price of $5 for the pair. These look exactly like Heresy's minus the tweeter. I have removed everything from the cabinets, cleaned them up, and both the woofer and midrange horn work perfectly. I removed the crossover, which looks impressive, but I have no idea about reusable parts. Instead of trying to scavange from them, I took advantage of Parts Express free shipping and have these things on the way: 260-235 50 Watt Control Panel 270-050 Pioneer AHE60-51F 3-1/2" Horn Tweeter 260-210 Crossover 3-Way 8 Ohm 800/5,000 Hz 100W 260-309 Gold Speaker Terminal Rectangle The control panel will be used for balancing the horns, the Pioneer tweeter has good specs and hopefully it will integrate well. As I said, I know nothing about building a crossover, so I went with one that had cut offs similar to specs I researched on Heresys. The terminal box speaks for itself. I would like to build a floor standing speaker with enough volume to allow the woofer to overcome the Heresy's limitation on low end extension. A ported design would be fine if it will improve performance. Here are some crude paintshop drawings of what I am thinking. Front Topview I will be using 3/4 MDF and plenty of bracing. I don't know how I will finish these yet, but I am thinking a black piano finish. These will be a gift for my father-in-law so I want them to be something he will cherish and use. Thanks for reading this longish post, and I look forward any of your comments and help. Remember I am a speaker building novice, so go easy on the technical terms. Kendal
