[quote user="DrWho"] [quote user="SET12"]I to have experimented with outboard electronic crossovers. But I found a better approach IMO. I would prefer to do it within my amplifiers! I saw this once in Sound Practices Magazine and I thought it was a stroke of genius! Why you may ask! Simply the elimination of gain stages! Every gain stage you have in series is a form of compression and another loss of transparency. I often hear it in amplifier comparisons in watt for watt[/quote

Larry, I just measured my North Creek 3mh 8 AWG and as close as I can measure them they sure are massive. Diameter 6.5 inches Height 1.5 inches Inside Diameter of Hole 1.5 inches DCR .10 The .16mh 8 AWG Diameter 3 inches Height 1.5 inches Inside Diameter of Hole 1.5 inches DCR .02 SET12

[quote user="GotHover"] [quote user="idahodewitt"]Since you have tried it, why would you not recommend doing it? [/quote] First, as stated before you will need tools to test the inductors afer you are done winding them. Second, it is difficult to wind the coils exactly. Most of all because inductors are fairly inexpensive, and for your application I would use a quality Iron core for your 1.6mH like a super Q inductor from parts express and a aug14 foil inductor for the HF. If

[quote user="GotHover"] [quote user="SET12"] Unfortunately Iron Cores sound compressed in contrast to Air Cores due to "hysteresis distortion" DeanG in ALK's Inductor shoot out thread mentioned a listening test he did with a Super Q Inductor that had the same DCR as his Solen 10 AWG Air Core's and as he said it was imediately obvious to him that the Iron Core sounded lean! http://forums.klipsch.com/forums/t/38976.aspx?PageIndex=1 Perhaps some people can live

Larry, Unfornately there is more involved in wrapping your own. One is a good accurate meter. Two is how you do it! When I was going to school, a few of my instructors chastised me for buying the North Creeks but on the North Creek site there was some obvious reasons why I thought I shouldn't as even the schools Inductance meter was not calibrated close enough. And I thought it sounded a little messy, so I bite the bullet to speak of, and I have no remorse for doing it! From North Creek Is "Perfect

[quote user="idahodewitt"] Bob, Do you have a heavier gauge autoformer for the KLF-20? Larry [/quote] Hi Larry, Yes, Bob does have the better autoformer here at his site http://www.critesspeakers.com/ And specificly here http://www.critesspeakers.com/autotransformers.html You have the 7A which is for a -10db reduction so you'll need his 3504 replacement. I would estimate its core to be about 50% larger. I would say you can also hear imroved bandwidth, greater air in recordings with

[quote user="idahodewitt"] Whoa! That thread went on forever............. Lots of good information though. I've used North Creek before......good stuff and good people to work with. I'll see about getting the Duelund resistors for the highs and their caps for the mids. Then the heavy gauge wire inductors from North Creek if they're still available. Plus, get the 80uf electrolytic out of there. I'll experiment around with the 2uf caps to hear what sounds best and see what

Best Cap I have heard! Duelund by far VSF Copper (the square on the right), the Silver is even better or the Cast. Their Graphite resistors with a negative temperature coefficient (long slender brown) are very affordable and way ahead of the competition IMO. Even when used in parallel with my tweeters they are the sweetest! SET12

[quote user="idahodewitt"] Bob, Thanks so much for the schematic! That's just what I needed. Now I can figure out how to put a new x-over together. I may do an outboard one that I can change out different types of caps on for capacitor auditioning purposes. Another question...... Is there any reason that I should not use a different type of inductor to replace the iron core one? I was thinking of using the Alpha Core ribbon type of inductor. Would that work well for this application

Crossover performance can be huge. Though I like Bob Crites upgrades especially the tweeters, I feel if you want more you have to go further than Bob's work as I have. See Larry's KLF20 thread for my comments and picture with links. SET12
