SDA 3.1 TL crossover build on gimpod boards

5ljnx0t7rx48.jpg

Wow after some 2 year delay I am hoping to tackle this project. My brain is starting to clear and the parts look like a project instead of random spaghetti so I have hope. Fortunately there are some good threads here even with gimpods site down. I see one jumper required on his schematic and the rest looks standard. I planned to change the big inductor with optional connector so I will have to figure that out.

It will be a bit, but I figure posting here will be like telling some I intend to do it and motivate me. Wish me luck and happy new year.

    Will you be replacing the sub-bass drive inductors also?

    Thank God for different opinions. Imagine the world if we all wanted the same woman
  • xschop - yes i bought replacement sub-bass inductors and probably have the optional connectors gimpod recommended. I just haven't laid it out to see how that connection gets made.

    Hey Ricardo. Kids are keeping me busy with school. I am giving myself a few weekends to do this. hopefully less than 8. My goal for this weekend is to pull one crossover for reference and see how all of it is supposed to connect. It is a much easier project than the LSi9s I did, but it has been a while.

    My 3.1TL's have Tony's Boards with Gen 1 Sonicaps and Mills Resistors.

    You are in for a treat when the new x-overs completely run in ;)

    Subscribed. Let me know if you decide to part with the original boards.

    xschop- I’ll let you know if I have them available. I ah e not yet opened the speakers

    Set the parts out today. I found the J5 jumper and the E H jumper. I assume i wasn’t going to use polyswitch or resister because i didn’t order any so I see the S1 jumper.

    I have circled my question spots. The P3 tweeter output connector does not match the board. I verified the part number. I’ll look through posts to see if anyone shows where this goes. Gimpod.com on wayback scroll over position page doesn’t work and I don’t have winzip yet to try the archive of his page

    Second question is the PR holes for large inductor. He recommended the connector shown for remote mount. I did not see the male counterpart suggested to make this work. Anyone use this method?

    Thanks.

    Ok the rar files answered my questions. Now I just need to figure out how to connect to the PR connector

  • Been awhile since I've been here, but saw this thread and the fact that Gimpod's site is no longer. A long time ago, I downloaded the site for my own reference on my 3.1s. I have included the site in a zip folder. You should just be able to download this, extract it and open the index.html file within the first folder and your browser should be able to handle the rest.

    I know it's a little late, but hopefully you still find this useful.

    How are the 4 stereo midwoofers wired up? The schematic does not show.
