Tekton Double Impacts

Now that's a thought Grannyring, the money saved using the Gaia II's could go towards the cost of the upgrades. Once I get my SE's I'll seriously look into modding my DI's. It would be very interesting comparing the modded DI's to the SE's. My biggest concern is soldering new wire onto the tweeters without damaging them. Any tips on minimizing heat to the tweeter? Would Duelund caps work? I've heard good things about the big Duelunds. 

@mac48025 Placing an alligator or crocodile clip on the terminal between the wire and the terminal mount will act like a heatsink and not overheat and possibly desolder the tinsel leads to the diaphragm.

Edit: As a precaution if the alligator clip you use is very high tension and has really sharp teeth, maybe put a layer of aluminum foil between it and the litze wire behind the terminal.  Some alligator clips are meaner than others. No sense damaging the delicate tweeter wire. 

No worries on the tweeters. First off no need to rewire all of them for the upgrades.  You can just deal with the tweeter connections to the crossover. Use this heat sink as @jcarcopo refers to....

Easy and you will not ruin the tweeters. 

@grannyring Yes sir, that's the one.  No teeth at all is best. (deletes funny double entendre) 

@mac48025. You will want to mod the SEs as they will have the better drivers. I can assure you the crossover parts can be upgraded in the SE reflecting more of what I used.

Duelund would not be possible due to the crazy high cost. Remember the cap values are as high as 220uf, 68uf, and 10 or 12uf. Sure in the 1.5 uf cap on the center tweeter. A 12uf Duelund CAST cap costs $1300. A 40uf Duelund cap costs $3300. A custom 68uf and several combined caps to get you to 220uf would cost some $10,000 per speaker! Oh my! If you go this route have a master woodworker make you a great set of new cabs and outboard crossover boxes. Two inch thick front baffle and works!

No worries, great choices beyond Duelund here!  On values up to 15uf you can use the wonderful Jupiter copper foil or  Jupiter HT Aluminum foil caps in wax. On the large value caps I used Mundorf Evo Oil to make up the 220uf cap. The best sounding large value cap I know of is the Mundorf Supreme Evo Silver & Gold. It is expensive, but nothing like the cost of the Duelund. The stock SEs will not have parts of this quality. Also go with Path Audio resistors. All of these are too big for the cab and will placed externally. 

These parts are better sounding than the electroltyics or lower range Clarity film caps used in the stock and SE speakers.
