Hello:
I replaced the foam ring on the original drivers when they wore out but the sub doesn't sound the same :( . It tends to clip/shudder when loud LFE play. I am now wondering if I can replace the drivers with something like "Dayton Audio UM12-22 12" Ultimax DVC Subwoofer 2 Ohms Per Coil" or Eminence Lab 12C High Power 12" Subwoofer Speaker Driver 4 Ohm. Would it work? Has anyone here done anything like this with good results?

The specs of the subwoofer are as follows:
POWER OUTPUT: 400 watts RMS
AMPLIFIER DISTORTION: Less than 0.03% from 20 to 125 Hz at full output into subwoofer drivers
INPUT IMPEDANCE: 15 Kohms
NOISE: better than -90 dB relative to full output
TYPICAL ROOM RESPONSE: 20 - 200 Hz ± 2 dB (THX position)
ANECHOIC RESPONSE. 18 - 125 Hz ± 2 dB (Anechoic position)
DIMENSIONS (H x W x D): 23 1/4" x 15 1/2" x 26" (MX-5000 Mk II)
WEIGHT: 105 lbs.

The sub is a push-pull design and uses two 12", 4-ohm drivers.

What do you guys think? Doable?

Thanks!

Have you checked with M&K about replacement drivers?

Otherwise I think it might be difficult to find drivers with the correct parameters to match up, so you may not know what you are getting in that box of chocolates.

Reach out to Ken Kreisel and see if he has any suggestions, or perhaps he could design you one... he'd likely know.

I had seen you had suggest the same to someone else some time back. I sent Ken an email a few months back but he did not reply. I sent him one just now. Hope he replies.

I hear a lot of good things about SVS and have been looking into them as well. If I can't find a way to repair the ones I have I might add a couple of SVS subs. I contacted them and they suggested supplementing them with PB-1000 Pros since they are close to the power output of my current subs and are also ported. Although, I think the MX5000s are closer to a sealed sub as they employ the push-pull design.
decisions, decisions... :)
