I have a 2 x 12 cab that I am replacing the speakers in. I got the cab for free, & the prob. is that a prev. owner cut the holes larger, & they are a bit too big for my replacements. I need to fill in probably 1/2" or more all the way around.
I could cut a ring & glue it in, that would be tedious work; anyone ever do a repair like this? Maybe there are pre-cut "fix-it" rings one can buy?
Ideas/suggestions?
Thanks!
1. If there is room in the front you could cut a rectangular face plate out of at least 1/2 " plywood with proper sized holes in it and mount it on top of the existing mounting surface or it could be mounted on the inside as well . Most speakers can be mounted either from the top or the bottom . Glue it and attach it with wood screws to eliminate air gaps . Adhesive caulk is a good option also .
2. I don't know if the sonic properties of the cabinet will be affected adversely but you could try a square piece of sheet metal and cut holes correctly sized for the speakers . I did this with a horn once and it worked fine . The sheet metal wouldn't be so thick as to create clearance issues with the front speaker grill and it probably should be epoxied (caulked?) so there are no air leaks .
Wood is cheaper and easier to work with provided you have ( or know someone who has ) woodworking skills and equipment .
If I claim to be a wise man , it surely means that I don't know .
Diceman,
I thought about cutting a rectangular face plate out of ply & attaching it to the front just as you suggested. It seems like that would look like heck :mrgreen: but I guess it doesn't really matter that much to me, as this is just a cab for my practice room. I woun't be gigging with it or anything like that.
The extra weight might be a bit of an issue if I were gigging with it, but since I'm not...
And, I really don't have the means to do a decent job w/ sheet metal. I may opt for the plywood faceplate. Kind of like a "Frankenstein cab", lol!
A speaker grill of some sort would hide the cobble-job from sight and save embarrassment from the ridicule musician friends and family members would almost assuredly subject you to . (I know mine would !) Upholstery fabric is pretty good for the purpose and provides protection for the speaker cones .

Can't you remove the face-plate? Sometimes the face plate is held in place by screws. You could replace the entire face-plate and cover it in grill cloth (if the original stuff would come off you could use that or buy new cloth)
I started with nothing - and I've still got most of it left.
Did you know that the word "gullible" is not in any dictionary?

This is actually an angled cab that is probably meant for subwoofer use for in a car. I believe the MDF is all air nailed/glued together from factory. I have pieces of MDF, so I guess what I will do at this point is glue & screw (or air nail) a new face plate on it as suggested. I suppose that is the easiest method now.
If I removed the piece that is there, I would have to saw at the joint & cut through the screws. I've done that before on other projects, that is an option. I guess I will also be ordering up some new cloth & recovering the whole thing...or maybe vinyl/tolex this time around.
Funny how little jobs turn into big ones real quick - :roll:
