I haven’t heard of the V2 JL fathoms having issues. The V1 definitely did. I haven’t heard the Martin Logan’s you have but can say the F113 is way better IMO to the Rythmic F12 I had. Much more articulation and punch.
JL Audio Fathom
I've been very tempted to upgrade my 2x 12in Martin Logan 1100x subs to 2x JL Audio Fathom v2 subs. for reference the 1100x retail ~1300$ and the JL Audio 5k. I am very happy with the Martin Logans which are very nicely integrated with my Sabrina X speakers. Do you think it would be worth upgrading to the Fathoms?
No REL for me because I don't want made in China FYI.
