Kenny_G Posted October 16, 2018 Share Posted October 16, 2018 I'm going to open up my KG4's and do Crites recap kit's and titanium tweeter diaphragms. Since the cabinets are open would it be worth sealing all the internal corner joints ? With what material ? Read many places its best not to you silicone based sealers due to acidic off gas causing corrosion issues . What is the best thing to use to seal the drivers ?

jason str Posted October 16, 2018 Share Posted October 16, 2018 Had a few sets and never had any leaky cabinets like other models, you can play a 25 Hz test tone through them and listen for leaks at the seams and around drivers and passives with a small vacuum or air line at your ear. Air escaping will be quite noticeable, repair where needed. Use speaker gasket tape to seal drivers. Don't overpower the drivers for the test, 3/16" or so of cone travel is plenty.

pzannucci Posted October 17, 2018 Share Posted October 17, 2018 I am not familiar with the KG4 cabinets but if they are wood / MDF vs some of the others like KLFs, It wouldn't hurt to pour some Tight Bond II in the corners. That will help seal and ensure the cabinets are tight. Quote Link to comment Share on other sites More sharing options...
Maz4bz Posted October 24, 2018 Share Posted October 24, 2018 I like PVA. Any brand will do. Non toxic, no smell, water based, dries clear, forms a bond with timber that is often stronger than MDF or particle board you've joined, fills gaps and is cheap as chips. The bracing in my KG 5.5's is glued in with PVA. I've built several subs using just PVA. No screws or nails, just plain PVA. 👍 Quote Link to comment Share on other sites More sharing options...
