Ready to take the upgrade plunge on my SDA 1.2tl's.
I am nervous to start upgrading these. I have the skills needed to get the job done but I love these speakers! The upgrades I have planned:
1. Glue driver magnets
2. Dynamat Driver baskets
3. Larry's Rings
4. Re-glue a cross brace that has come loose
I have a few questions:
Glue - JB Weld was recommended here. I have 2 tubes of PL Premium I can use which is a Polyurethane construction adhesive. Says it bonds to metal. Would this be a decent choice to use?
Areas to glue - I have seen some pictures but wanted to clarify - Glue around the top and bottom of where black part of the magnet meets the metal part? I also have heard of people gluing around where the magnet assembly meets the basket. Is this done only for drivers that are riveted or is there benefit to doing it regardless?
Larry's Rings - I read DarqueKnight's guide on installing them (thank-you!). One thing I did not notice was how to remove the hurricane nuts that are embedded in the wood to hold the existing hex nuts in place. Has anyone done this, if so how did you remove them?
Moretite - I have had my drivers out before and the gaskets are all in good shape. When doing the "push" test my speakers are air tight. Assuming I don't damage any of the gaskets am I okay to put them back in or do the rings slightly change where the driver sits int he holes?
Bass Braces - There is only one loose that I am aware of so far. It buzzes at high volumes. Wondering if anyone else has run into this problem and how you fixed it. The brace was secured with hot glue, I assume I can just remove the existing hot glue and re-glue it. Should I use hot glue or something stronger like the PL Premium?
Any help/suggestions would be appreciated!
After all this I am hoping to use Gimpod's XO boards to upgrade the crossovers then be done with it.
