Two drivers in my LS/FX surround speakers have gone bad and they no longer make replacements. I found that the LS/FX has MW4850 drivers and the CS350 center speaker has MW4851 (magnetically shielded version). So I purchased a CS350 and found that it had three MW4851s and one MW4801. Now it's my understanding that there should be four of the MW4851s, so this must have been a replacement driver or it was from factory that way. My question is... How close is the MW4801 to the MW4851? The MW4801 is from the CS250 center.
I only needed two drivers and still have one more spare from this, but was just wondering if it's worth keeping the 4801 as a true emergency back up, or if it's not close enough for even that.
