Repair Or Replace Sub

Only if you concluded the F series ARO didn’t provide your room any worthwhile improvement.

Regarding driver size I found a v1 F-113 every bit as potent as the Velodyne DD-18 I compared it to in my room.
The ARO’s auto only calibration gave a slight edge to the flexibility of Velodyne’s manual adjustability.

Considering Mike’s positive repair experience I'd go for the repair and keep an eye out for a used e-110 to slave off your F-112 or the JL Audio CR-1.

I don’t use the ARO because my Anthem STR does the same thing but for all speakers. In that case would you recommend trying something else?

I use an Anthem STR also. In my system, it tends to roll off the sub slowly, which smooths FR of the mains in the octave above the crossover frequency. One reason that works is that the JL Audio Fathom is cleaner than most subs above the usual sub range. That for me is a reason to stick with JL Audio -- though I admit I have not researched performance of competitive subs.

@mike_in_nc Thanks for the advice! I think I’m leaning to repair. It seems like they haven’t changed even the new versions much so it is worthwhile to invest more in making this one like new!
