Great advice from Mike and the JLAudio techs however I
don't see mixing an F112 and F113 as being problematic at
all. Both will be tonally similar, if not exact, and
have the same design philosophy. Though amplifier output
is higher in the F113, I don't think volume output will
be that much different so to make blending the two subs
I have been running four subs(pair Klipsch RT-10d's, SVS
SB13 Plus, Revel B15) in my main HT/music rig for some
time now and could not be happier with the results. I
will not tell you it was a short and simple task to get
it "right" but with countless hours of
placement changes and EQ(Audyssey MultEQ XT and onboard
sub EQ's), I feel my efforts have been successful.
Two subs from the same company as similar as the F112 and
F113 are, you will not have to put in the time and
effort I have to get good results.
