Using Krell rca & bal outputs for the same channel

Why would I do that?
My sub has a highpass filter above 65hz. The dedicated sub channel can have info above that. So how can I get the missing freqs above 65hz. I can get a second sub but I’d rather not.
Since Krell’s RCA & balanced outputs are active at the same time, I can send the sub channel to another speaker using a Y cable to get the missing info. I’m thinking if I must use a Y cable and overtax a speaker with sub info, I’d send it to a rear speaker.
Does anyone know if using both outputs will affect the sound? The manual says that both outputs are active but to connect using only one. Will there be impedance issues? I also have an Audyssey EQ between the PrePro and the amp, so I would use the Y cable from sub and one of the rear to the EQ’s rear channel which will turn the analog signal into digital for EQing and back to analog for the amp.

I doubt they're missing, aren't they coming through your main speakers? You would certainly notice that big a gap in frequencies in any musical content. Just because there is an upper cutoff for the LFE channel doesn't mean that the output to the main LR channels has a low cutoff at that frequency.

This, of course, should be taken with a grain of salt, as I have an HT system, but don't really know how it works as a technical matter. But I hear plenty of lower frequency info from my main speakers on movies.
