New speaker mounting holes? [message #27136] Wed, 12 December 2018 11:41 Go to previous message

Well, I finally got around to replacing the speakers in the 3x12 cab I bought a few months ago. The cab has Jensen C12Ns in it now (two of which are blown), and I bought three of the Kustom/KEI "Turbo" speakers, which look to be a good choice for replacement, they have the cool silver dome with the black vent that I like, and the price was right ($50 each, brand new in original boxes).

So I pulled one of the C12Ns last night, put the new KEI speaker in, and.....the mounting bolts don't fit - the C12N had an ever so slightly smaller radius, so the bolts don't line up with the new speakers.

Not a huge problem, all I need to do is rotate it 22-1/2 degrees, drill new holes and move the mounting studs, right?

I see the nuts that hold the baffle board in place - after I remove those, does the whole board, including the grillcloth, come out? If so, how do I then remove the grillcloth so I can drill new holes and move the studs? Or is there some way to remove the grillcloth with the baffleboard in place?

It may be obvious once I get the board removed, but I wanted to check here first, in case I'm missing something in my understanding.

Oh, and I did mic up and record some guitar playing through the only good C12N, and will compare that to the KEIs once installed. I just played a short chord progression, recorded it into Reaper, then played that back through the amp with a mic in front of the speaker, that way I can easily reproduce the exact same audio source with the new speakers.
