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 use the balanced outs for my main speakers and they run full range. This works very well and there is no crossover to muck up the sound of my mains.
I am concerned about 2 issues:
1) To send my mains full bass because
a) Wearing and overtaxing my cones with low freqs, my Cremonas Mains go down to 32Hz.
b) Usins a Y cable in the audio chain for my mains. (I must use the Y because of my EQ that sits between the PrePro and the amps)
2) My EQ prefers a crossover and has alot of software dedicated to working with the crossover. I don't want to sacrifice the EQ's crossover optimization for my mains.

Based on the above preferences, I could simply use a rear speaker. Since in Dolby and DTS soundtracks, the rear speakers are used around 5% of the time. So it will be like I have 2 subs. Although it just occurred to me that I should use a Y cable going out as well. Since the EQ will be testing the LFE channel.

Yeah...
I think I'm just going to get a new Sub. It big time sucks Sonus Faber put a crossover in it. Who the heck would want a crossover in a sub when it won’t be compatible with all the audio formats? It's a $4,500 sub.

It matches my other Cremonas. I’m emotionally attached to it as well. It’s the only component I actually nick named. I call it “Big Mama.” This thing is huge.
But if it isn’t compatible I don’t see that I have a choice.
I spent years with placement & many cables getting the sound just right with Big Mama.
I am so upset. I wasted years of my life and much emotion on it. Now I see how divorced people must feel.

Anyway, I was just saying that if I must mix the sub into another channel (To get the missing freqs between 66-120hz), I want to take the path of least resistance. So since I don’t want to mess with mains that only leaves the rear speakers. Also, since this is only a problem with movies and not music, I wont be messing with my music system if put the LFE channel from DTS and Dolby into the rears.

But this just sounds so crazy. If I wasn’t emotionally attached, I would just get a normal sub. I should have researched what the dials on the sub meant. I had no idea what a “Low Pass Filter “ Meant.

What would be a good matching sub for $2,500 for the Cremonas?

Doesn't your sub have LFE inputs? They bypass the xover.
