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.

@rauliruegas where does the Sabrina go as low as 1.1 ohms? I’ve seen 2+ but not anything as low as you state. I think the MA8950 would drive them well just as @upstateaudiophile says as it will drive 2,4,8 ohm loads with 200W regardless of which tap is used. I disagree that the MA8950 is a mediocre integrated amp.

@rauliruegas I’m not entirely sure of what you are saying. You mentioned low impedance as a limiting factor that the Mac can’t handle then switched to the autoformers can’t recreate the frequency without some sort of coloration. I have an admittedly limited understanding of how the autoformer works and why it is used however I have never read anything that indicates that it’s incapable of effectively recreating an audio signal in a particular frequency. I believe the Macs are relatively linear in their output. I’m sure the engineers at McIntosh have sorted this all out and know better than you or I, so I will defer to their expertise. My ears tell me they have done an excellent job. If there is some literature you can point me to that explains your position I would be happy to read it.

@rauliruegas you keep saying the same thing over and over without explaining what you mean.  There is also no 1.1ohm impedance in the curve for the Sabrina that I have seen.  Sorry, I'm hijacking this thread and I don't want to do that.  I understand the autoformer matches the load that's how it is able to consistently deliver the same wattage regardless of load.
