Even if the sub is jumpered as you say, the sub's DSP will add a delay relative to the LFR's woofers. How do I compensate for that?
I imagine the subwoofer output goes through the DSP as well rather than being hard-wired... in fact I think it has to since it needs to combine inputs from the L and R channels.
There could still be different path lengths as a consequence of not going through any filter logic, but it's also possible the subwoofer signal goes through a delay of approximately the same length as the filter stages. Don't know.
Hold on, I answered the opposite question from the one you were asking... and it's too late to delete the post... and I have to go out and try to get ready for the next big dump of snow... today looks to be the last snow-free day of the year... and I obviously haven't had anywhere near enough coffee yet.
So ignore this post other than as a potential source of amusement.
And no, I haven't had time to set up the LFR1100's yet, but at least they are finally in the right part of the house with the strapping taken off the boxes.
