I have 3 F112 v1, since 2008 iirc, I’ve also had need to have them serviced, keeping my boxes shipping them to either AZ or FL. The service is excellent and timely: about 7-10 turn around. The fact that they can be serviced is a plus. That they are still in business even with some negative feelings by a few says a lot about them as a company. The good news is they are stunning, powerful, fast and adjustable in every manner. I don’t use the ARO room correction but let my Trinnov deal with it. My system is a dual purpose room, both analog and HT. I play vinyl and digital music plus movies. Getting 3 subs in phase with the mains is challenging, I’ve done it manually in the past, but not much need now. I don’t think you’d go wrong getting the F112.
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.
