I am in need of two or more t-nuts to secure the woofer. For some reason, one is missing and the other has spun out requiring some minor repair to the MDF (chip board?). The thread size is 10x32 and the base with the prongs is about .5 inch in diameter. I have searched the local hardware stores and can find t-nuts that will fit the machine screw, but the diameter of the base is too wide which extends beyond the edge of the speaker cutout. I have considered cutting the extra material off the t-nut. But as far as I can tell, the L300s are original in nearly every way and I would like to keep them in this condition.
Anyone that can point me to a source would be much appreciated.
