Hi,
I have a pair of Rokit 5's I bought used and one of them may be exhibiting symptoms of the 5" mid being blown, and I would like to be able to inspect and replace it. However, I am stuck at how to actually take these apart. There are many screws on the back holding the amp on, but when I remove all of the perimeter ones nothing will budge, and the remaining screws in the center of the plate amp have little resistance when unscrewing, indicating that they are not holding the amp in place. Here is a picture to illustrate this:
Is it possible there is some kind of sticky gasket or glue holding the plate amp in place? Do I have to pry the amp out?
Anyone have any experience with these or how to actually get them apart? Thanks in advance.

I would guess there is a gasket. And it wouldn't be unexpected for it to be a tell-tale that they have been dissassembled.

I'm not worried about resale, or anyone knowing I took them apart, I just want to be able to open them without damage. I won't be sending them to KRK ever, and I'll probably keep them around until they die, so I want them to have a useful life.
It would suck if KRK put that gasket in just to deter people from fixing it themselves.
I've seen raw drivers for them being sold on ebay quite regularly, so there must be other people somewhere swapping drivers out... so at least its not impossible.

Only undo the screws around the outside , the inner ones hold the amp internals to the backplate. Probably has a gasket *of sorts* and will need a bit of "encouragement" to get it out...........
Well after a few hours I finally got it, I had to end up shoving the amp plate out via the port on the front using a dowel, the gap between the amp and the enclosure was so tight it was impossible to get anything between there to pry it out. Mine is the v1, so it doesn't have the allen bolts on the front, but the trim ring around the speaker was only held in with friction and some asphalt-based adhesive so after about 20 mins with a butter knife I was able to remove it and get at the screws and get the woofer out.
I still can't discern if its fully blown, since it only makes a light buzzing noise during certain low notes at considerable volume levels, but further testing will eventually yield the answer to that one.
This was my 2nd attempt and it took me about 45 mins overall just to get it taken apart, it really is impossible to get the amp off without nudging it from the front first, which is what I failed to try before.
Thanks for all the tips guys, and hopefully if anyone else ever has this problem they can gain a little help from this thread.

I can get some pics up tomorrow no problem, and would running an impedance curve require a woofer tester?
No need for a woofer tester.

I have a spreadsheet that helps with calculations.
If you have a problem with the voice coil/motoer it will usually show up in the impedance curve.

i tried replacing the opamps in my KRK's and one of them did fine, the other one developed an as of yet undiagnosed problem on the eq board (the one with the knobs attached to it) and the speaker makes lots of popping and crackling noises but i have to turn it off rigth away cause it sounds like the cone is going to fly out of the speaker... looks like it too... anyway, since i took em apart and had a camera around here's what they look like inside 🙂
