Wardsweb Posted November 27, 2022 Share Posted November 27, 2022 Here is how I spent my Sunday morning. A big shout out to Dean for the parts. The cedar boards I cut from a log I have had in my shop for over 10 years. I knew it would come in handy one day. Anyway, I would change a couple things, if I were ever to do this again, but over all not bad for something that gets hidden away inside a pair of Heresy's. 12 Quote Link to comment Share on other sites More sharing options...

babadono Posted December 6, 2022 Share Posted December 6, 2022 Hey, hey watch out ain't those the certified Klipsch genuine super duper no compromise capacitors installed in all new Klipsch speakers? 1 Quote Link to comment Share on other sites More sharing options...
Marvel Posted December 7, 2022 Share Posted December 7, 2022 I love the look of the cedar! 1 Quote Link to comment Share on other sites More sharing options...
captainbeefheart Posted December 7, 2022 Share Posted December 7, 2022 Looks great but I wouldn't trust a crimp connection on the capacitor leads. Quote Link to comment Share on other sites More sharing options...
OO1 Posted December 7, 2022 Share Posted December 7, 2022 Take a look at the suspended capacitors , and the air flow underneath the capacitors . Quote Link to comment Share on other sites More sharing options...

Nah, just the part you need for the network to work as intended. Klipscheads: "We love our Klipsch stuff, it sounds great!" Also Klipscheads: "Klipsch is lying to us and holding us back with all of these crappy parts!" I have contributed to this mess and now the chickens have come home to roost. 1 Quote Link to comment Share on other sites More sharing options...

It all depends on using the correct tool for the optimum crimp. I have Amphenol mil spec crimpers that were required when I was working deep space satellites. Done correctly, a crimp connection is better than solder and one of the reasons why they are used by NASA. Given a crossover is low voltage, low current and a fairly stable platform, I think they will be fine. Then again if something fails, it's an easy repair. 1 Quote Link to comment Share on other sites More sharing options...

I only mentioned it because I have seen failures from people using these exact type of crimp connectors with electrical components thin leads in various Industrial control panels. They most likely used standard electrician crimp tools and probably didn't understand how to make a quality crimp connection like you. As you point out it's a simple fix regardless. Now that I know you have a solid background and know what you are doing I wouldn't have even posted. I figured I could possibly help someone that may not know anything about quality connections but you are a professional so disregard my nonsense.

Deang Posted December 12, 2022 Share Posted December 12, 2022 I avoid it because it’s only 20 gauge wire, and once you crush it, there isn’t much lead material left at the end of crimp to maintain mechanical integrity, especially inside of a loudspeaker cabinet which is about the worst place possible for a network.

geoff. Posted December 12, 2022 Share Posted December 12, 2022 …I always cut the lead twice as long as needed, bend it in half, and double the lead going into the crimp Really nice looking work by the OP by the way. Cutting the wood cross sectional is stunning. Needs a Lexan case, unless there are no other lifeforms present, lol. Quote Link to comment Share on other sites More sharing options...

I heat up the plastic and remove the metal 'tube' portion of the crimp connector, crimp the connection, then solder it and cover in heat shrink. It takes me a while to complete my projects... 1 Quote Link to comment Share on other sites More sharing options...

Anyone who can't take constructive criticism should reevaluate their objection. All good. There will always be someone with more and someone with less; money, education, experience, life, etc. You can learn from everyone, from the janitor to the CEO. 8 Quote Link to comment Share on other sites More sharing options...
