What size of T-nuts should I use for mounting the Eminence Delta 12LF driver for 3Pi? The ones that I get in my local hardware store are M4/M5 4 prong and are too wide. Any other options? Wayne, do you have any suitable T-nuts and screw that I can buy from you and get them ship together with the kit? Many thanks.
When I use T-Nuts, I usually use 10-32 size with button head or hex head screws. But for the H290 compression horn and for the woofers on one π, two π and three π speakers, I like to use these fasteners: Black pan screws for mounting small drivers T-Nuts are good when post-construction serviceability is a concern, like for prosound speakers. But if you won't be going inside your speakers a lot, these screws are fine. They look good and will hold until about 20 loosening/tightening cycles, when the wood will stretch enough to tear through. <br(.*)
Thanks Wayne. Could you please check the link as it seems to be broken. 20 cycles should be enough for me. Do you use brass/steel inserts at all? Do I need any add any sealing between the driver and the baffle? Or is the gasket that come with the Delta 12 good enough? Thanks alot.
Perhaps IDXmart has gone out of business. Here are some from Parts Express: #6 x 3/4" Deep Thread Pan Head Screws, Black Finish #8 x 3/4" Deep Thread Pan Head Screws, Black Finish If you use a good quality wood, no inserts will be needed. The gasket on the driver is fine, so I never apply any gook.
