Not really what you are talking about but here is another way hook up your subs.
JL audio subs will let you play both the LFE from your reciever AND the two channel high pass at the same time but you need a sub for each channel.
JL audio inputs are summed.
There is a right and left input on each sub. On the right if you send your right preout channel signal to the sub and from the sub to the amp. On the extra “left input” send the LFE channel. Do the same on the left side.
This setup allows the subs to be blended with the mains through the crossover but still play the LFE signal. You can then boost the LEF from the reciver like normal and extend the range of your mains at the same time.
I have ran mine this way for years with my subs set up for two channel but when using the HT reciver (by pass mode) the subs still play the LFE.
For what it is worth I think subs can be localized (in a large proper room) and should sit beside the speaker they are extending.
