I have to admit this is sort of a cross post from another forum that I made but I realized that there is much more activity on this forum.
I bought a Yamaha Stagepas 400i from a pawn shop with one blown compression driver. STAGEPAS 400i/ 600i - Overview - PA Systems - Professional Audio - Products - Yamaha - United States Apparently this is a common problem with these speakers so I can either put in the same compression drivers or try to fix the issue of them failing but substituting them with something else. I do not want to modify the crossover or anything else. I probably don't want to change brands of drivers either...I am not going to search the planet for some obscure option.
The OEM speaker is a Celestion CDX1-1070 which is rated at 8 ohms, 12 watts, 106 dB sensitivity, and 2200 Hz recommended crossover. They are super cheap and could be considered disposable. Celestion CDX1-1070 8 ohm 12W Pro Audio Compression Driver T5916
There are two Celestion options that look "close" to me but I don't know what I'm doing. 😀 They all have the same bolt pattern and rough dimensions.
CDX1-1415, 8 ohms, 20 watts, 104 dB sensitivity, and 2500 Hz recommended crossover.
Celestion CDX1-1415 | 8 ohm 20W Neodymium Pro Audio Compression Driver T5343
CDX1-1425, 8 ohms, 25 watts, 108 dB sensitivity, and 2500 Hz recommended crossover.
Celestion CDX1-1425 | 8 ohm 25W Neodymium Pro Audio Compression Driver T5344
Are either of these options good options? Will they last longer than the original ones? Will it sound good?
Thanks, Steve

There seems to be a lot of guessing in this process. By not changing the crossover it has become much more difficult to answer this question. Wouldn't you at least get something of similar sensitivity and adjust the resistors to set the level?
According to the literature I just went through the crossover is 3.2 kHz so that should meet the spec of the "higher end" options? I've included a photo of the board.
I am 100% green in this area so I really don't know much from a practical standpoint. I more or less understand the mathematical side.
