After picking up some shorter cap screws today, I intended to get the 604-8G drivers installed in the cabinets. Then, all that would be left would be to install the shelf braces, install Owens Corning 703 damping, and build and install the crossovers.
On the second driver installation, a t-nut came loose while tightening, despite being recessed and epoxied in/over. I’m not worried about seven cap screws holding the driver, but epoxy debris is caught between the cone and grill cloth, the t-nut is reflective and slightly pressing out from the grill cloth, and I’m afraid the screw/t-nut will rattle. Show-stopper.
My plan is to remove the front baffle, 604-8G and all, take loose the staples holding the upper corner of the grill cloth, remove the offending bolt/t-nut, remove the driver, re-staple the grill cloth, re-install the front baffle, and re-install the driver. I might take a bolt out of the other speaker to match…
The biggest pitfall I can foresee is damaging the grill cloth, necessitating re-covering one or both baffles. I wish I had done that myself to begin with rather than farming it out, but it’s still not an effort and expense to look forward to.
Nonetheless, I’ll keep moving.
