Repair Or Replace Sub

My JL F112 v1 blew it’s cone out the other day. I called my dealer and they said JL would replace it and the caps (since they were getting to that point too) for ~$900. While I love this sub it did get me thinking if it would be better to take the opportunity to spend say $1500 on a new sub from someone like rythmik rather than pour more money into the old one. Can anything compare to the JL in that price range or am I just going to be disappointed.
