Klipsch RF-3 II Damaged Woofer Cone

I have a Klipsch 5.1 system including some RF-3 II floorstanding mains. I have not used the grills and have been fortunate until recently when my nephews damaged one of the cones by kicking a small ball inside. This was the result:

Now, trying to search on this issue, the only thing I really came up with is the dust cap being dented, but that is not the issue. Couple of questions, is it worth replacing this (assuming it is fairly easy as I have no experience with speaker repair), or will it not affect sound quality and simply putting on the grills now will be good enough to hide the problem and prevent future issues.

As for a replacement, searching ebay, I was able to find this:

http://www.ebay.com/itm/Klipsch-K-1083-SV-RF-35-Replacement-Woofer-Part-No-120861-/300837274393?pt=US_Speaker_Parts_Components&hash=item460b4c8319

However, the model number is slightly different from the K-1083-SB (V instead of B) listed on the product page on

http://www.klipsch.com/rf-3-ii-floorstanding-speaker

Also, the part no is also different between the two listings.

Any advice is appreciated. Thanks.

Thanks for that link.

So is it fairly easy to replace these and do you recommend doing it? I assume removing the four screws and disconnecting a couple wires is all that is required. Is that safe to say or will I be in for some surprises? Thanks.

Oh, seems easy enough then.

My only last question would be, would you expect the damage to affect the sound quality of the woofer drastically? If it is not a huge deal, I can always just leave it covered behind the grill and save the cash.

Thanks for all the help and info!
